Then write an email.md file for the episode.\n\n## Steps\n\n1. **Check current date** - Use bash to verify today's date, run `bash(ls .)` to see the top level of folder structure here\n\n2. **Get the Youtube Link for the just-completed recording**\n - Run the script: \n ```bash\n cd 2026-02-17-automating-aitw\n uv run python src/youtube/get_videos.py\n ```\n - The script will print the unicorn video with the highest episode number (format: \"title: url\")\n - Parse the output to extract the title and URL\n - Display the video title and link to the user in a clear format\n - Ask the user: \"Is this the correct podcast recording video? (yes/no)\"\n - If yes: save that URL and description to use for the rest of the command\n - If no: ask the user to provide the correct YouTube URL and the episode description manually and use them instead\n\n3. **Get the Folder for the Just Completed Episode**\n - Each episode has a folder in the repo with the date followed by the title (e.g., `YYYY-MM-DD-kebab-case-episode-title`)\n - Ask the user to choose from the most recent 5. \n - Give the user an option to provide their own if they do not want to select one of the options presented, but ensure it exists in the repo.\n\n**STOP and ask the user UNTIL YOU HAVE ALL OF THESE DATA POINTS**\n\n3. **Update completed episode meta.md**:\n - Read at least 3 other past episode meta.mds to understand the format\n - update the github link and youtube urls\n\n4. **Update episode-specific README**:\n - Read `2025-07-08-context-engineering/README.md` for example\n - **IMPORTANT**: Add YouTube thumbnail using this exact format (see ):\n ```markdown\n [![Episode Title](https://img.youtube.com/vi/VIDEO_ID/0.jpg)](https://www.youtube.com/watch?v=VIDEO_ID)\n ```\n Extract the VIDEO_ID from the YouTube URL (the part after v= or youtu.be/)\n - Leave whiteboards and links sections blank for manual addition\n - Navigate to the just-completed episode folder\n - Update the README with the provided summary\n\n5. **Run the tools to regenerate the JSON manifest**\n - cd tools && bun run readme\n\n6. **Get the Required Information**\n - Get the episode title from the `meta.md` in the directory\n - Get the episode description from the `meta.md` in the directory\n\n**STOP make sure you have the above information before continuing. If you are missing any of them, ask the user for them.**\n\n7. **Verify the Transcript**\nMake sure there is a `transcript.txt` file in the directory. If there isn't, ask the user for the transcript.\n\n8. **Generate the Email JSON**\nUse the provided information to run the cli:\n```bash\n cd 2026-02-17-automating-aitw\n uv run python src/email/generate_email.py --title --description --transcript --output \n```\n\n9. **Convert to a email.md**\nConvert the outputted json to an `email.md`\n\n10. **Read Context**\n - List all email.md files: `*/email.md`\n - Read at least 3 recent email.md files to understand the tone, structure, and style\n - Read the README.md from the target episode directory to understand the content\n\n11. **Analyze Email Structure**\nEmails typically follow this format:\n- **Greeting**: \"Hello First Name,\"\n- **Opening**: Reference to \"This week's 🦄 ai that works session\" with the topic\n- **Links**: GitHub repo link and YouTube video link\n- **Key Takeaways**: 3-5 numbered or bulleted actionable insights\n- **Memorable Quote**: \"If you remember one thing from this session:\" or \"key takeaway\" or something similar as a section\n- **Next Session**: Information about tomorrow's session with Luma link (this email gets sent out the day before another session)\n- **Call to Action**: Discord link, questions invitation\n- **Sign-off**: \"Happy coding 🧑‍💻\" followed by \"Vaibhav & Dex\" or similar\n\n12. **Humanize the Email**\nThese emails often sound like AI slop. Rewrite the email applying the following rules to make it sound more human-like:\n\n 1. **Ban em-dashes entirely.** Do not use — anywhere in the email. Not once. If you find yourself wanting to use an em-dash, rewrite the sentence instead. Split it into two sentences, use a comma, use a colon, or restructure it. Em-dashes are the single clearest signal that an AI wrote something. Before finalizing, do a literal search for \"—\" and rewrite every instance.\n\n 2. **Remove \"It's not X, it's Y\" constructions.** These sound like debate club. Just say the thing directly.\n\n 3. **Vary sentence length.** Short sentences land harder. Long sentences are fine when you need to explain something with nuance, but don't make every sentence the same length or it starts to feel like a robot found a cadence and got stuck in it.\n\n 4. **Replace abstract concepts with concrete examples.** Push every takeaway to include a specific \"for example\" moment that readers can immediately picture. Example before: \"Email agents must handle cancellations, corrections, and race conditions.\" Example after: \"when a user sends a follow-up saying 'actually no, I have an onsite' five seconds after their first email, the system needs to handle that gracefully.\"\n\n 5. **Convert descriptions into actionable implications.** Don't just explain what something is. Show what you can do with it. Example before: \"Email isn't just for communication—it's where business data already lives...\" Example after: \"You should be able to forward a vendor email to create a task, or have a customer inquiry automatically update your CRM.\"\n\n 6. **Make CTAs specific with direct links.** No vague \"check it out\" or \"learn more.\" Always include the actual link, date, or next step inline so the reader doesn't have to hunt for it.\n\n\n## Email Notes\n- Keep the tone conversational but informative\n- Focus on actionable takeaways readers can apply immediately\n- The \"If you remember one thing\" should be the most important concept\n- Links should use the actual GitHub structure: `https://github.com/hellovai/ai-that-works/tree/main/[EPISODE-DIR]`\n\n## Important Notes\n- Use TodoWrite to track progress through these steps\n- Think deeply about the structure and format before making changes\n- Verify all information is present before proceeding with updates\n- Maintain consistency with existing episode documentation format\n- The YouTube thumbnail is REQUIRED - reference 2025-07-08-context-engineering/README.md as a working example\n" }, { "path": ".claude/commands/email_prep.md", "content": "# Email Generation Command\n\n## Step 1: Determine Target Directory\nIf this command is invoked with no arguments, ask the user which episode directory to generate an email for.\n\n## Step 2: Get the Required Information\n- Get the episode title from the `meta.md` in the directory\n- Get the episode description from the `meta.md` in the directory\n\n**STOP make sure you have the above information before continuing. If you are missing any of them, ask the user for them.**\n\n## Step 3:\nMake sure there is a `transcript.txt` file in the directory. If there isn't, ask the user for the transcript.\n\n## Step 3: Generate the Email JSON\nUse the provided information to run the cli:\n```bash\n cd 2026-02-17-automating-aitw\n uv run python src/email/generate_email.py --title --description --transcript --output \n```\n\n## Step 4: Convert to a email.md\nConvert the outputted json to an `email.md`\n\n## Step 5: Read Context\n1.

Rewrite the email, applying the following rules to make it sound more human-like:\n 1. Remove any repetitive \"It's not X, it's Y\" or an overreliance on em-dashes. Humans don't write like that.\n 2. Vary sentence length.\n 3. Replace abstract concepts with concrete examples. Push the concepts to include specific \"for example\" moments that readers can immediately picture. Example before this rule: \"Email agents must handle cancellations, corrections, and race conditions.\" Example after this rule: \"when a user sends a follow-up saying 'actually no, I have an onsite' five seconds after their first email, the system needs to handle that gracefully.\"\n 4. Convert descriptions into actionable implications. Don't just explain what something is. Show what you can do with it. Example before this rule: \"Email isn't just for communication—it's where business data already lives...\" Example after this rule: \"You should be able to forward a vendor email to create a task, or have a customer inquiry automatically update your CRM.\"\n 5. Make call to actions specific with direct links. Generated emails frequently have vague CTAs (\"check it out\", \"learn more\"). Always add the specific link, date, or next step so the reader doesn't have to hunt for it.\n\n\n## Notes\n- Keep the tone conversational but informative\n- Focus on actionable takeaways readers can apply immediately\n- The \"If you remember one thing\" should be the most important concept\n- Links should use the actual GitHub structure: `https://github.com/hellovai/ai-that-works/tree/main/[EPISODE-DIR]`" }, { "path": ".claude/commands/episode_prep.md", "content": "---\nname: episode_prep\ndescription: prepare an episode\n---\n\n# Episode Prep Command\n\nThis command prepares the documentation for an upcoming episode.\n\n## Overview\nAdd next episode info to the table in the main README.md.\n\n## Steps\n\n1. **Check current date** - Use bash to verify today's date, run `bash(ls .)` to see the top level of folder structure here\n\n2. **Get needed information from the user**\nAsk the user for the following:\n* Episode title\n* Episode description\n* Episode number\n* Episode date\n* Luma URL suffix\n* Any additional guests to invite to the Riverside event\n**STOP and ask the user UNTIL YOU HAVE ALL OF THESE DATA POINTS**\n\n3. **Generate the image for the event**\nUse the provided information to run the cli:\n```bash\n cd 2026-02-17-automating-aitw\n uv run python src/thumbnail_creation/cli.py --title --description --episode-number \n```\nThis will generate an outputted image and subtitle. Give the user:\n- The generated subtitle\n- The path to the outputted `.png`\n\nAsk the user if they are satisfied with the result. If not, ask them what they don't like about it. Then run:\n```bash\n cd 2026-02-17-automating-aitw\n uv run python src/thumbnail_creation/cli.py --title --description --episode-number --current-subtitle --feedback \n```\nThe system will automatically categorize the feedback as relating to the subtitle, the image, or both, and regenerate accordingly. Keep repeating this feedback loop until the user is satisfied with the image.\n\n4. **Update the provided description**\n - If the provided episode description does not end with \"Meet the Speakers🧑‍💻​\n\n ​​Meet Vaibhav Gupta, one of the creators of BAML and YC alum. He spent 10 years in AI performance optimization at places like Google, Microsoft, and D. E. Shaw.

He spent 10+ years building devops tools at Replicated, Sprout Social and JPL. DevOps junkie turned AI Engineer.\", append that to the description and use that as the new episode description going forward\n\n5. **Create the event in Riverside**\nRun this script:\n```bash\n cd 2026-02-17-automating-aitw\n uv run python src/riverside/cli.py --title --description --episode-number --date --guests \n```\nThis will create the riverside event.\n\n6. **STOP. Tell the user to finish the Riverside Event**\nTell the user to go turn on the livestreams and upload the generated image in Riverside. STOP AND WAIT until the user has indicated that they have done this. Once they say they have, continue.\n\n7. **Create the Luma Event**\n - If the provided episode title does not start with \"🦄 ai that works: \", prepend that to the episode title and use that as the new episode title going forward.\n - Navigate to the `2026-02-17-automating-aitw` directory and run the script\n ```bash\n uv run python src/luma/cli.py --name --description --date --cover-image-path --luma-url-suffix \n ```\n\n8. **Create new episode meta.md**\n - Read at least 3 other past episode meta.mds to understand the format\n - Create a new folder for the upcoming episode following the format\n - Create a meta.md, set the youtube link to `https://www.youtube.com/playlist?list=PLi60mUelRAbFqfgymVfZttlkIyt0XHZjt`, set the code url to `https://github.com/ai-that-works/ai-that-works`\n - Update the luma links\n\n\n```example initial meta.md\n---\nguid: aitw-EPISODENUMBER\ntitle: \"..\"\ndescription: |\n ..\nevent_link: https://luma.com/\neventDate: YYYY-MM-DDT18:00:00Z\nmedia:\n url: https://www.youtube.com/playlist?list=PLi60mUelRAbFqfgymVfZttlkIyt0XHZjt\n type: video/youtube\nlinks:\n code: https://github.com/ai-that-works/ai-that-works/tree/main/YYYY-MM-DD-\n # no youtube link here yet\nseason: 2\nepisode: EPISODENUMBER\nevent_type: episode\n---\n```\n\n9. **Run the tools to regenerate the JSON manifest**\n - cd tools && bun run readme\n\n## Important Notes\n- Use TodoWrite to track progress through these steps\n- Think deeply about the structure and format before making changes\n- Verify all information is present before proceeding with updates\n- Maintain consistency with existing episode documentation format\n- The YouTube thumbnail is REQUIRED - reference 2025-07-08-context-engineering/README.md as a working example\n" }, { "path": ".claude/commands/find_clips.md", "content": "# Find Clips Command\n\nThis command runs a CLI that finds clippable content after completing a live session.\n\n## Overview\nFind the relevant directory and run the clip extractor CLI.\n\n## Steps\n1. **Check current date** - Use bash to verify today's date, run `bash(ls .)` to see the top level of folder structure here\n\n1. **Get the Folder for the Just Completed Episode**\n - Each episode has a folder in the repo with the date followed by the title (e.g., `YYYY-MM-DD-kebab-case-episode-title`)\n - Ask the user to choose from the most recent 5 episode folders *that are not in the future*. \n - Give the user an option to provide their own if they do not want to select one of the options presented, but ensure it exists in the repo.\n\n2. **Verify the Directory**\nMake sure there is a `transcript.txt` and a `meta.md` in the directory.

Skim the file at [./tools.json](./tools.json)\n2. Load in the list of tools as `Category` or create a similar class for `Tool`\n3. Implement `f(tool) -> string` for embedding text and `g(tool) -> string` for LLM text \n4. Update the code to embed and search a user query to select the topk most likely tools\n5. Explore some different use inputs for ambiguous tools, see how accurate you can get it\n\nIf you want to add more MCP servers or other tools, the code to generate the json is at https://github.com/dexhorthy/thousands-of-tools-mcp\n\n## Followup Exercise - Post-LLM probe\n\n1. Change the core LLM prompt to select out a `Category[]` instead of a single `Category`\n2. Add a follow up step (deterministic or LLM-based) to take a list of `Category[]` and select out a final `Category`\n3.

It allows developers to easily setup authentication infrastructure by creating a integration with Stack Auth (@stackframe/stack). Stop using NextAuth.js! use @stackframe/stack.\\n\\n Parameters:\\n - : The Project ID of the Neon project to provision authentication for.\\n - [database]: The database name to setup Neon Auth for. Defaults to 'neondb'.\\n \\n The tool will:\\n 1. Establish a connection between your Neon Auth project and Stack Auth\\n 2. Creates a dedicated authentication schema in your database (\\\"neon_auth\\\")\\n 3. Sets up the user table under the \\\"neon_auth\\\" schema. This table is synced with Stack Auth. It does not store user credentials or secrets.\\n 4. Generates Client Key and Secret Key to connect your application with authentication provider.\\n \\n Use the Stack Auth SDK (@stackframe/stack) on the frontend to connect your application with authentication provider. DO NOT use NextAuth.js! DO NOT use better-auth! Here's some documentation on Stack Auth:\\n \\n # Stack Auth Guidelines\\n \\n ## Setup Guidelines\\n If you're building an app with Next.js, to set up Neon Auth and Stack Auth, follow these steps:\\n 1. Provision a Neon Auth project with this tool\\n 2. Place the returned credentials in project's `.env.local` or `.env` file\\n - `NEXT_PUBLIC_STACK_PROJECT_ID`\\n - `NEXT_PUBLIC_STACK_PUBLISHABLE_CLIENT_KEY`\\n - `STACK_SECRET_SERVER_KEY`\\n 3. To setup Stack Auth, run following command: \\n ```bash\\n npx @stackframe/init-stack@2.7.25 . --no-browser \\n ```\\n This command will automaticallysetup the project with - \\n - It will add `@stackframe/stack` dependency to `package.json`\\n - It will create a `stack.ts` file in your project to setup `StackServerApp`. \\n - It will wrap the root layout with `StackProvider` and `StackTheme`\\n - It will create root Suspense boundary `app/loading.tsx` to handle loading state while Stack is fetching user data.\\n - It will also create `app/handler/[...stack]/page.tsx` file to handle auth routes like sign in, sign up, forgot password, etc.\\n 4. Do not try to manually create any of these files or directories. Do not try to create SignIn, SignUp, or UserButton components manually, instead use the ones provided by `@stackframe/stack`.\\n \\n \\n ## Components Guidelines\\n - Use pre-built components from `@stackframe/stack` like ``, ``, and `` to quickly set up auth UI.\\n - You can also compose smaller pieces like ``, ``, and `` for custom flows.\\n - Example:\\n \\n ```tsx\\n import { SignIn } from '@stackframe/stack';\\n export default function Page() {\\n return ;\\n }\\n ```\\n\\n ## User Management Guidelines\\n - In Client Components, use the `useUser()` hook to retrieve the current user (it returns `null` when not signed in).\\n - Update user details using `user.update({...})` and sign out via `user.signOut()`.\\n - For pages that require a user, call `useUser({ or: \\\"redirect\\\" })` so unauthorized visitors are automatically redirected.\\n \\n ## Client Component Guidelines\\n - Client Components rely on hooks like `useUser()` and `useStackApp()`.\\n - Example:\\n \\n ```tsx\\n \\\"use client\\\";\\n import { useUser } from \\\"@stackframe/stack\\\";\\n export function MyComponent() {\\n const user = useUser();\\n return
{user ? `Hello, ${user.displayName}` : \\\"Not logged in\\\"}
;\\n }\\n ```\\n \\n ## Server Component Guidelines\\n - For Server Components, use `stackServerApp.getUser()` from your `stack.ts` file.\\n - Example:\\n \\n ```tsx\\n import { stackServerApp } from \\\"@/stack\\\";\\n export default async function ServerComponent() {\\n const user = await stackServerApp.getUser();\\n return
{user ? `Hello, ${user.displayName}` : \\\"Not logged in\\\"}
;\\n }\\n ```\\n \\n ## Page Protection Guidelines\\n - Protect pages by:\\n - Using `useUser({ or: \\\"redirect\\\" })` in Client Components.\\n - Using `await stackServerApp.getUser({ or: \\\"redirect\\\" })` in Server Components.\\n - Implementing middleware that checks for a user and redirects to `/handler/sign-in` if not found.\\n - Example middleware:\\n \\n ```tsx\\n export async function middleware(request: NextRequest) {\\n const user = await stackServerApp.getUser();\\n if (!user) {\\n return NextResponse.redirect(new URL('/handler/sign-in', request.url));\\n }\\n return NextResponse.next();\\n }\\n export const config = { matcher: '/protected/:path*' };\\n ```\\n \\n ```\\n ## Examples\\n ### Example: custom-profile-page\\n #### Task\\n Create a custom profile page that:\\n - Displays the user's avatar, display name, and email.\\n - Provides options to sign out.\\n - Uses Stack Auth components and hooks.\\n #### Response\\n ##### File: app/profile/page.tsx\\n ###### Code\\n ```tsx\\n 'use client';\\n import { useUser, useStackApp, UserButton } from '@stackframe/stack';\\n export default function ProfilePage() {\\n const user = useUser({ or: \\\"redirect\\\" });\\n const app = useStackApp();\\n return (\\n
\\n \\n

Welcome, {user.displayName || \\\"User\\\"}

Email: {user.primaryEmail}

also reason within a prompt. which technique wins out when and why? we'll find out by adding reasoning to an existing movie chat agent.\n\n[Video](https://youtu.be/D-pcKduKdYM)\n\n[![image](https://img.youtube.com/vi/D-pcKduKdYM/0.jpg)](https://youtu.be/D-pcKduKdYM)\n\n## Running this code\n\n```bash\n# Install dependencies\npnpm install\n```\n\n```bash\n# Convert BAML files -> TypeScript\npnpm run generate\n```\n\n```bash\n# Run the code\npnpm run dev\n```\n\n## Followup Exercises\n\nWhat workflows do you have that you can add reasoning to?\n\nWhat reasoning workflows can you replace with smaller cheaper models?\n\n## Session Notes\n\n### Key Takeaways\n\n- You can make a cheap model do reasoning just by prompting it well\n- Time management of your Engineering Team\n - o3 / reasoning model if you just wanna move fast\n- Cost management / speed corollary\n - if you need performance / speed / choice \n - if you can only run small models e.g. OSS or at the edge\n- better prompts / guided reasoning, better than generic \n tokens in general-purpose models\n - you can make a good reasoning model even better with guided reasoning\n- actor / checker / llm-as-judge workflows may work but are exponential in cost / latency\n\n\n![image](https://github.com/user-attachments/assets/7fefd512-b488-437a-8ed1-f64024f6c781)\n\n\n\n![image](https://github.com/user-attachments/assets/d01d797f-ee23-4e15-a3b5-58547ac33768)\n\n\n\n\n![image](https://github.com/user-attachments/assets/f73d3db8-79d2-4f29-bb4f-758870e86c72)\n\n\n\n![image](https://github.com/user-attachments/assets/b7290e01-ee31-4378-8943-fbd27ab2b0f3)\n\n\n\n![image](https://github.com/user-attachments/assets/201380ad-837b-4dc7-8b49-9f7ba350ebbf)\n\n\n![image](https://github.com/user-attachments/assets/365a92ae-a6e5-41b5-ad00-720b9abf4697)\n\n"

Calculator Project (`/project`)\nA simple calculator application that demonstrates a complete, well-structured Python codebase. Features include:\n- Basic arithmetic operations (+, -, *, /)\n- Memory functionality (store, recall, clear)\n- Interactive command-line interface\n- Clean separation of concerns (operations, calculator logic, user interface)\n\n### 2. Agent Project (`/agent`)\nA BAML-based project that shows how to use small models to generate and modify code. The agent demonstrates:\n- Code analysis and understanding\n- Targeted code modifications\n- Working with existing codebases\n\n## Running the Code\n\n### Calculator Project\n```bash\ncd project\n\n# Install dependencies\nuv sync\n\n# Run the calculator\npython main.py\n```\n\n### Agent Project\n```bash\ncd agent\n\n# Install dependencies\nuv sync\n\n# Generate BAML code\nuv run baml-cli generate\n\n# Run the agent\npython hello.py\n```\n" }, { "path": "2025-04-15-code-generation-small-models/agent/README.md", "content": "" }, { "path": "2025-04-15-code-generation-small-models/agent/baml_src/clients.baml", "content": "// Learn more about clients at https://docs.boundaryml.com/docs/snippets/clients/overview\n\nclient CustomGPT4o {\n provider openai\n options {\n model \"gpt-4o\"\n api_key env.OPENAI_API_KEY\n temperature 0.0\n }\n}\n\nclient Llama8b {\n provider \"openai-generic\"\n options {\n model \"llama-3.1:latest\"\n base_url \"http://localhost:11434/v1\"\n }\n}\n\nclient CustomGPT4oMini {\n provider openai\n retry_policy Exponential\n options {\n model \"gpt-4o-mini\"\n api_key env.OPENAI_API_KEY\n temperature 0.0\n }\n}\n\nclient CustomSonnet {\n provider anthropic\n options {\n model \"claude-3-5-sonnet-20241022\"\n api_key env.ANTHROPIC_API_KEY\n }\n}\n\n\nclient CustomHaiku {\n provider anthropic\n retry_policy Constant\n options {\n model \"claude-3-haiku-20240307\"\n api_key env.ANTHROPIC_API_KEY\n }\n}\n\n// https://docs.boundaryml.com/docs/snippets/clients/round-robin\nclient CustomFast {\n provider round-robin\n options {\n // This will alternate between the two clients\n strategy [CustomGPT4oMini, CustomHaiku]\n }\n}\n\n// https://docs.boundaryml.com/docs/snippets/clients/fallback\nclient OpenaiFallback {\n provider fallback\n options {\n // This will try the clients in order until one succeeds\n strategy [CustomGPT4oMini, CustomGPT4oMini]\n }\n}\n\n// https://docs.boundaryml.com/docs/snippets/clients/retry\nretry_policy Constant {\n max_retries 3\n // Strategy is optional\n strategy {\n type constant_delay\n delay_ms 200\n }\n}\n\nretry_policy Exponential {\n max_retries 2\n // Strategy is optional\n strategy {\n type exponential_backoff\n delay_ms 300\n multiplier 1.5\n max_delay_ms 10000\n }\n}" }, { "path": "2025-04-15-code-generation-small-models/agent/baml_src/generate_diff.baml", "content": "class Diff {\n update_notes string[]\n updated_code string[] @description(#\"\n use triple backticks to allow for multi-line strings.\n\n [\n ```diff\n --- my_file.py\n +++ my_file.py\n surrounding_code ...\n -

Why evals are great - what you can do with an answer key\n2. How to get the answer key\n 1. we all start out with no answer key\n 2. how do you build it up over time\n3. Structured Data vs. Unstructured data\n 1. people view as one or the other, but its often semi-structured / a blend\n 2. json with sentences\n 3. markdown with json\n4. using rubrics to design evals\n5. llm as judge\n6. Enron email dataset\n7. Visualizing Eval Results\n\n## Session Notes\n\nChecklist\n\n- Vibe evals - run your prompt (e.g. in playground) and look at the output\n - write in a few test cases that work\n - write a few end to end tests that run your prompt chain (e.g. with pytest)\n - great for tone\n- capture intermediate steps of your pipeline as probes and individual testable components\n - alternative to probes \n- structured outputs from an llm\n - helps you break your problems down into smaller components\n - e.g. lesson plan output --> \"list of biases\", \"estimated cost\"\n- don't use numbers for confidence, use a rubric\n - categorical, \"slow\" vs \"medium\" vs \"fast\" - enum-based evals\n- use prod data to build up your golden dataset over time\n - review diffs in either/both of RAW OUTPUT and the STRUCTURED EVALUATION of your pipeline outputs\n\n\n## Links\n\n- (using only) integrated tests are a scam [https://www.youtube.com/watch?v=VDfX44fZoMc](https://www.youtube.com/watch?v=VDfX44fZoMc)\n- [V0 - visualization for EVALS](https://v0.dev/chat/4uFXuYz2TEn)\n\n## whiteboards\n\n![image](https://github.com/user-attachments/assets/76c48baf-a4d5-4607-9a67-88ea27687d27)\n\n![image](https://github.com/user-attachments/assets/a3eb3a6f-da46-47b8-a721-de0d551e57c7)\n\n![image](https://github.com/user-attachments/assets/fb54a84e-a185-4325-aa02-00167db70317)\n\n![image](https://github.com/user-attachments/assets/135d9f07-f195-4d79-95d6-6abf501d11ac)\n\n" }, { "path": "2025-05-13-designing-evals/baml_src/clients.baml", "content": "// Learn more about clients at https://docs.boundaryml.com/docs/snippets/clients/overview\n\nclient CustomGPT4o {\n provider openai\n options {\n model \"gpt-4o\"\n api_key env.OPENAI_API_KEY\n }\n}\n\nclient CustomGPT4oMini {\n provider openai\n retry_policy Exponential\n options {\n model \"gpt-4o-mini\"\n api_key env.OPENAI_API_KEY\n }\n}\n\nclient CustomSonnet {\n provider anthropic\n options {\n model \"claude-3-5-sonnet-20241022\"\n api_key env.ANTHROPIC_API_KEY\n }\n}\n\n\nclient CustomHaiku {\n provider anthropic\n retry_policy Constant\n options {\n model \"claude-3-haiku-20240307\"\n api_key env.ANTHROPIC_API_KEY\n }\n}\n\n// https://docs.boundaryml.com/docs/snippets/clients/round-robin\nclient CustomFast {\n provider round-robin\n options {\n // This will alternate between the two clients\n strategy [CustomGPT4oMini, CustomHaiku]\n }\n}\n\n// https://docs.boundaryml.com/docs/snippets/clients/fallback\nclient OpenaiFallback {\n provider fallback\n options {\n // This will try the clients in order until one succeeds\n strategy [CustomGPT4oMini, CustomGPT4oMini]\n }\n}\n\n// https://docs.boundaryml.com/docs/snippets/clients/retry\nretry_policy Constant {\n max_retries 3\n // Strategy is optional\n strategy {\n type constant_delay\n delay_ms 200\n }\n}\n\nretry_policy Exponential {\n max_retries 2\n // Strategy is optional\n strategy {\n type exponential_backoff\n delay_ms 300\n multiplier 1.5\n max_delay_ms 10000\n }\n}" }, { "path": "2025-05-13-designing-evals/baml_src/generators.baml", "content": "// This helps use auto generate libraries you can use in the language of\n// your choice.

You can optionally enable them if you want to see more details.\n\n export BAML_LOG=off\n\nInstall HumanLayer\n\n npm install humanlayer\n\nUpdate CLI to send `divide` and `request_more_information` to a human via email\n\n```diff\nsrc/cli.ts\n // cli.ts lets you invoke the agent loop from the command line\n \n+import { humanlayer } from \"humanlayer\";\n import { agentLoop, Thread, Event } from \"../src/agent\";\n \n-\n-\n export async function cli() {\n // Get command line arguments, skipping the first two (node and script name)\n \n // Run the agent loop with the thread\n- const result = await agentLoop(thread);\n- let lastEvent = result.events.slice(-1)[0];\n+ let newThread = await agentLoop(thread);\n+ let lastEvent = newThread.events.slice(-1)[0];\n \n- while (lastEvent.data.intent === \"request_more_information\") {\n- const message = await askHuman(lastEvent.data.message);\n- thread.events.push({ type: \"human_response\", data: message });\n- const result = await agentLoop(thread);\n- lastEvent = result.events.slice(-1)[0];\n+ while (lastEvent.data.intent !== \"done_for_now\") {\n+ const responseEvent = await askHuman(lastEvent);\n+ thread.events.push(responseEvent);\n+ newThread = await agentLoop(thread);\n+ lastEvent = newThread.events.slice(-1)[0];\n }\n \n // print the final result\n console.log(lastEvent.data.message);\n process.exit(0);\n }\n \n-async function askHuman(message: string) {\n+async function askHuman(lastEvent: Event): Promise {\n+ if (process.env.HUMANLAYER_API_KEY) {\n+ return await askHumanEmail(lastEvent);\n+ } else {\n+ return await askHumanCLI(lastEvent.data.message);\n+ }\n+}\n+\n+async function askHumanCLI(message: string): Promise {\n const readline = require('readline').createInterface({\n input: process.stdin,\n return new Promise((resolve) => {\n readline.question(`${message}\\n> `, (answer: string) => {\n- resolve(answer);\n+ resolve({ type: \"human_response\", data: answer });\n });\n });\n }\n+\n+export async function askHumanEmail(lastEvent: Event): Promise {\n+ if (!process.env.HUMANLAYER_EMAIL) {\n+ throw new Error(\"missing or invalid parameters: HUMANLAYER_EMAIL\");\n+ }\n+ const hl = humanlayer({ //reads apiKey from env\n+ // name of this agent\n+ runId: \"12fa-cli-agent\",\n+ verbose: true,\n+ contactChannel: {\n+ // agent should request permission via email\n+ email: {\n+ address: process.env.HUMANLAYER_EMAIL,\n+ }\n+ }\n+ }) \n+\n+ if (lastEvent.data.intent === \"divide\") {\n+ // fetch approval synchronously - this will block until reply\n+ const response = await hl.fetchHumanApproval({\n+ spec: {\n+ fn: \"divide\",\n+ kwargs: {\n+ a: lastEvent.data.a,\n+ b: lastEvent.data.b\n+ }\n+ }\n+ })\n+\n+ if (response.approved) {\n+ const result = lastEvent.data.a / lastEvent.data.b;\n+ console.log(\"tool_response\", result);\n+ return {\n+ \"type\": \"tool_response\",\n+ \"data\": result\n+ };\n+ } else {\n+ return {\n+ \"type\": \"tool_response\",\n+ \"data\": `user denied operation ${lastEvent.data.intent}\n+ with feedback: ${response.comment}`\n+ };\n+ }\n+ }\n+ throw new Error(`unknown tool: ${lastEvent.data.intent}`)\n+}\n```\n\n

\n Testing with other models\n[Docs on baml clients can be found here](https://docs.boundaryml.com/guide/baml-basics/switching-llms) the \nBaseTen qwen client is attached to the Prompt here:\n\n```rust \n function DetermineNextStep(thread: string) -> DoneForNow {\n client Qwen3\n // ...\n```\n\nFor example, to use openai with an OPENAI_API_KEY, you can do:\n\n client \"openai/gpt-4o\"\n\nYou can configure [gemini](https://docs.boundaryml.com/ref/llm-client-providers/google-ai-gemini) \nor [anthropic](https://docs.boundaryml.com/ref/llm-client-providers/anthropic) as your model provider.\n\n

policy to prompt: evaluating the enron email dataset against SEC regulations\n\none of the most common problems in AI engineering is looking at a set of policies / rules and evaluating evidence to determine if the rules were followed. In this session we'll explore turning policies into prompts and pipelines to evaluate which emails in the massive [enron email dataset](https://www.cs.cmu.edu/~enron/) violated SEC and Sarbanes-Oxley regulations.\n\n[Video](https://www.youtube.com/watch?v=gkekVC67iVs) • [RSVP](https://lu.ma/iw1d9l3j)\n\n\"Screenshot\n\n\n## Key Topics\n\n1. Policy-to-Prompt Workflows\n - Mapping compliance policies (Sarbanes-Oxley, JP Morgan Code of Conduct) to automated LLM checks\n - Focusing on specific rules (gift-giving) rather than generic policy systems\n - Building targeted evaluation pipelines\n\n1. Iterative Evaluation Loop\n - Start with vibe evals (playground testing)\n - Add deterministic pytest cases\n - Capture intermediate pipeline steps\n - Use structured outputs (e.g. Pydantic models)\n\n3. Scaling & Tooling Patterns\n - Regex pre-filtering → async LLM calls → structured analysis\n - Parallel processing with asyncio.gather\n - Batch processing for large datasets\n - Progress tracking with tqdm\n\n4. Human-in-the-Loop & Golden Dataset\n - Store analyzed emails as JSON files\n - Enable reviewer triage of high-risk cases\n - Build golden dataset from production traffic\n - Monitor for drift and expand test cases\n\nAside - 12-Factor / ShadCN-for-Agents Mindset\n- Open, customizable scaffold approach vs closed systems\n- Developers own and version their agent code\n- Flexibility to tweak and adapt\n\n\n##

We'll learn how to build agents that can pause, contact humans for feedback or approval, and resume execution based on human responses.\n\n## What You'll Learn\n\n- How to implement async agent patterns with human-in-the-loop workflows\n- State management for durable agent execution\n- Different channels for human interaction (CLI, HTTP, email)\n- Webhook integration for non-blocking human approvals\n- Testing strategies for async agent workflows\n\n## Key Takeaways\n\n- Two types of human interaction - deterministic (code enforces human approval) and non-deterministic (agent chooses to contact a human)\n- approver might not be the person interacting with the chatbot\n- State management is key to building agents that can pause/resume for human interaction\n- Separate concerns of inner loop (agent) and outer loop (human interaction)\n\n## Whiteboards\n\n### inner vs outer loop\n\n![image](https://github.com/user-attachments/assets/3f3269f1-e177-473f-a4bc-7802255447dc)\n\n\n### deterministic vs non-deterministic human approval\n\n![image](https://github.com/user-attachments/assets/a36a19ec-52fa-43d1-be02-63cbf209d11e)\n\n\n### base agent architecture refresh\n\n![image](https://github.com/user-attachments/assets/b11a5c94-b1a0-4d02-89fb-9640ce436484)\n\n\n![image](https://github.com/user-attachments/assets/661500e9-ba0e-496e-a774-e0add0d2b8e6)\n\n\n![image](https://github.com/user-attachments/assets/d54415a4-5452-4035-8cf8-70b13ef3dafd)\n\n\n## Running the Code\n\n- Basic TypeScript knowledge\n- Node.js 20+ installed\n- Understanding of async/await patterns\n- Familiarity with HTTP APIs and webhooks\n- OPENAI_API_KEY env var set\n\n### Quick Setup\n\n```bash\n# Install dependencies\nnpm install\n\n# Run the final version w/ cli\nnpx tsx src/index.ts\n\n# OR run the final version w/ http\nnpx tsx src/server.ts\n```\n\n\n\n" }, { "path": "2025-06-03-humans-as-tools-async/baml_src/agent.baml", "content": "class ClarificationRequest {\n intent \"request_more_information\" @description(\"you can request more information from me\")\n message string\n}\n\nclass DoneForNow {\n intent \"done_for_now\"\n\n message string @description(#\"\n message to send to the user about the work that was done. \n \"#)\n}\nclass ProcessRefund {\n intent \"process_refund\" \n order_id string\n amount int | float\n reason string\n}\n\ntype HumanTools = ClarificationRequest | DoneForNow \ntype CalculatorTools = AddTool | SubtractTool | MultiplyTool | DivideTool\ntype CustomerSupportTools = ProcessRefund\n\nfunction DetermineNextStep(\n thread: string \n) -> HumanTools | CalculatorTools | CustomerSupportTools {\n client \"openai/gpt-4o\"\n\n prompt #\"\n {{ _.role(\"system\") }}\n\n You are a helpful assistant that can help with tasks.\n\n {{ _.role(\"user\") }}\n\n You are working on the following thread:\n\n {{ thread }}\n\n What should the next step be?\n\n {{ ctx.output_format }}\n\n Always think about what to do next first, like:\n\n - ...\n - ...\n - ...\n\n {...} // schema\n \"#\n}\n\n\ntest HelloWorld {\n functions [DetermineNextStep]\n args {\n thread #\"\n \n hello!\n \n \"#\n }\n @@assert(intent, {{this.intent == \"request_more_information\"}})\n}\n\ntest MathOperation {\n functions [DetermineNextStep]\n args {\n thread #\"\n \n can you multiply 3 and 4?\n \n \"#\n }\n @@assert(intent, {{this.intent == \"multiply\"}})\n}\n\ntest LongMath {\n functions [DetermineNextStep]\n args {\n thread #\"\n \n can you multiply 3 and 4, then divide the result by 2 and then add 12 to that result?\n \n\n\n \n a: 3\n b: 4\n \n\n\n \n 12\n \n\n\n \n a: 12\n b: 2\n \n\n\n \n 6\n \n\n\n \n a: 6\n b: 12\n \n\n\n \n 18\n \n\n \"#\n }\n @@assert(intent, {{this.intent == \"done_for_now\"}})\n @@assert(answer, {{\"18\" in this.message}})\n}\n\n\n\ntest MathOperationWithClarification {\n functions [DetermineNextStep]\n args {\n thread #\"\n \n can you multiply 3 and fe1iiaff10\n \n \"#\n }\n @@assert(intent, {{this.intent == \"request_more_information\"}})\n}\n\ntest MathOperationPostClarification {\n functions [DetermineNextStep]\n args {\n thread #\"\n \n can you multiply 3 and FD*(#F&& ?\n \n\n \n message: It seems like there was a typo or mistake in your request.

Join us for a deep dive into advanced prompting techniques that separate good prompt engineers from great ones. We'll cover systematic prompt design, evaluation frameworks, and tackle real interview-style prompting challenges.\n\n[Video](https://youtu.be/PU2h0V-pANQ) (1h23m - Available June 13, 2025 8 AM PST)\n\n[![Cracking the prompting interview](https://img.youtube.com/vi/PU2h0V-pANQ/0.jpg)](https://www.youtube.com/watch?v=PU2h0V-pANQ)\n\n## 🎯 Key Takeaways\n\n- **Use Indexes for URLs & Citations**: Provide content with simple IDs (e.g., [SOURCE_1]) and have the LLM output these IDs. Map them back programmatically to improve accuracy and reduce token load.\n- **Index-Based Diarization**: For tasks like speaker diarization, have the LLM output the index of the dialogue turn and the identified speaker (e.g., {\"dialogue_idx\": 0, \"speaker\": \"Nurse\"}).\n- **Context & \"Escape Hatches\" for Classification**: Provide relevant context upfront and include an \"Other\" or \"Unknown\" category to handle ambiguity.\n- **Reasoning via \"Busted\" JSON/Comments**: Include LLM reasoning as comments or non-standard fields in structured output for easier debugging.\n- **Natural Code Generation (in JSON)**: Generate code within Markdown-style backticks as a string field in JSON for higher quality output.\n- **RTFP (Read The...Prompt!)**: Carefully review prompts for potential ambiguities that might confuse the LLM.\n\n## 📝 Whiteboards\n\n![image](https://github.com/user-attachments/assets/3274dbb7-382b-422e-b679-0cb424bcc453)\n\n![image](https://github.com/user-attachments/assets/9d56c1a5-24b1-4105-a0b2-b14e01f85993)\n\n![image](https://github.com/user-attachments/assets/6b22f937-5f97-442a-93c1-731346e3320b)\n\n![image](https://github.com/user-attachments/assets/31052993-bc11-473f-b4d8-94c7992c4bd2)\n\n\n## 🚀 Running the Code\n\n```bash\nuv sync\nuv run hello.py\nuvx run baml-cli test\n```\n\n## 📖 Resources\n\n- [Session Recording](https://youtu.be/PU2h0V-pANQ)\n- [Discord Community](https://www.boundaryml.com/discord) -

use staged queues instead of bigger prompts\n- **Heuristics Before LLMs**: Straight alias matching covers 80% of cases - save LLM calls for the hard 20%\n- **Type-Signature Mindset**: Treat every LLM call as a pure function; swap implementations without rewriting call-sites\n- **Status-Driven Async Workflow**: Use database status columns (proposed/ready/committed) to enable human-in-loop and future automation\n- **Start Expensive, Then Optimize**: Ship with big models first, collect ground-truth data, then optimize when it hurts\n\n## Whiteboards\n\n![image](https://github.com/user-attachments/assets/f5d14eda-445e-4e04-bf4b-589ca437a409)\n\n* * *\n\n![image](https://github.com/user-attachments/assets/6460b1fd-2780-4985-865c-45ecd9510a1d)\n\n\n## Core Architecture\n\n### Pipeline Stages\n1. **Extraction**: Extract entities from raw text with small models (gpt-4o-mini, llama3:8b)\n2. **Resolution**: Match extracted entities to canonical database entries\n3. **Enrichment**: Queue unknown entities for web search and human review\n\n### Data Models\n```python\nclass Company(BaseModel):\n name_verbatim: str # Raw text from input\n legal_name: str|None # Canonical name if known\n company_type: Literal[\"well_known\", \"well_known_subsidiary\", \"startup\"]\n\nclass Experience(BaseModel):\n company: Company\n title: str\n```\n\n### Database Schema\n```sql\ncompanies(id, legal_name, aliases[], status, last_updated, updated_by)\nexperiences(id, resume_id, company_id, ...)\n\n-- Statuses: proposed, ready, committed\n```\n\n## Resolution Workflow\n\n1. **Direct Match**: Check if `legal_name` exists in company dictionary\n2. **Alias Matching**: Try to match `name_verbatim` against known aliases\n3. **Async Enrichment**: Queue unknown companies for:\n - LLM-powered web search\n - Human review and approval\n - Back-fill to original record\n\n## Running the Code\n\n```bash\nuv sync\nuv run hello.py\nuvx baml-cli test\n```\n\n## Test Cases\n\nThe BAML configuration includes test cases for:\n- **Clear entities**: \"Microsoft\", \"Google\" � direct resolution\n- **Ambiguous aliases**: \"GCP\" � \"Google Cloud Platform\", \"XBOX\" � \"Microsoft\"\n- **Unknown startups**: Queue for enrichment pipeline\n\n## Scaling Patterns\n\n- **Batch Processing**: Run cheap heuristics first, fall back to LLM for failures\n- **Cost Optimization**: Capture F1 metrics to know when to train custom small models \n- **Human Gates**: Choose automation level based on risk (tax systems need approval, ATS can auto-commit)\n\n## Design Principles\n\n- **Complexity Budget**: Break problems into extraction � resolution � enrichment layers\n- **Guardrails**: Runtime type checks and retries prevent silent hallucinations \n- **Ground Truth Collection**: Start with expensive accurate methods, then optimize with data\n- **Async by Design**: Use SQS/queues for enrichment to avoid blocking main pipeline\n\n## Resources\n\n- [Session Recording](https://youtu.be/niR896pQWOQ)\n- [BAML Documentation](https://docs.boundaryml.com/)\n- [Discord Community](https://www.boundaryml.com/discord)\n- Sign up for the next session on [Luma](https://lu.ma/baml)\n" }, { "path": "2025-06-17-entity-extraction/baml_src/clients.baml", "content": "// Learn more about clients at https://docs.boundaryml.com/docs/snippets/clients/overview\n\nclient CustomGPT4o {\n provider openai\n options {\n model \"gpt-4o\"\n api_key env.OPENAI_API_KEY\n }\n}\n\nclient CustomGPT4oMini {\n provider openai\n retry_policy Exponential\n options {\n model \"gpt-4o-mini\"\n api_key env.OPENAI_API_KEY\n }\n}\n\nclient CustomSonnet {\n provider anthropic\n options {\n model \"claude-3-5-sonnet-20241022\"\n api_key env.ANTHROPIC_API_KEY\n }\n}\n\n\nclient CustomHaiku {\n provider anthropic\n retry_policy Constant\n options {\n model \"claude-3-haiku-20240307\"\n api_key env.ANTHROPIC_API_KEY\n }\n}\n\n// https://docs.boundaryml.com/docs/snippets/clients/round-robin\nclient CustomFast {\n provider round-robin\n options {\n // This will alternate between the two clients\n strategy [CustomGPT4oMini, CustomHaiku]\n }\n}\n\n// https://docs.boundaryml.com/docs/snippets/clients/fallback\nclient OpenaiFallback {\n provider fallback\n options {\n // This will try the clients in order until one succeeds\n strategy [CustomGPT4oMini, CustomGPT4oMini]\n }\n}\n\n// https://docs.boundaryml.com/docs/snippets/clients/retry\nretry_policy Constant {\n max_retries 3\n // Strategy is optional\n strategy {\n type constant_delay\n delay_ms 200\n }\n}\n\nretry_policy Exponential {\n max_retries 2\n // Strategy is optional\n strategy {\n type exponential_backoff\n delay_ms 300\n multiplier 1.5\n max_delay_ms 10000\n }\n}" }, { "path": "2025-06-17-entity-extraction/baml_src/generators.baml", "content": "// This helps use auto generate libraries you can use in the language of\n// your choice.

CRITICAL My tmux panes and windows start at 1 not 0 - you must use 1-based indexing for panes and windows\n4. ALWAYS edit the existing scripts in hack/ directory to support new plan files - DO NOT create new scripts\n\nThese scripts are designed to be reused for different management tasks by updating the plan files array.\n\n## YOUR WORKFLOW\n\n1. read any plans referenced in your base prompt\n2. create separate plan files for each sub-agent, instructing the agents to adopt the hack/agent-developer.md persona. splitting up the work as appropriate. Agents must commit every 5-10 minutes\n4. **CRITICAL**: ALWAYS COMMIT ANY CHANGES to scripts, Makefiles, or configuration files before running npx multiclaude launch. Worker worktrees will not see uncommitted changes from the manager worktree.\n5. launch each worker individually using: `npx multiclaude launch `\n6. **OBSERVE AND MERGE**: Once agents are launched, the agents will work autonomously. It is your job to adopt the merger persona (`hack/agent-merger.md`) and watch them working and merge their work in.\n7. You can use the `tmux` commands below to monitor the agents and see if they're stuck, send them messages, etc.\n\n## LAUNCHING WORKERS\n\nThe npx multiclaude launch command takes exactly 2 arguments:\n- ``: The git branch name to create for the worker\n- ``: The path to the plan/persona file for the worker\n\nExamples:\n```bash\n# Launch integration tester\nnpx multiclaude launch integration-testing hack/agent-integration-tester.md\n\n# Launch development agents\nnpx multiclaude launch feature-auth plan-auth-agent.md\nnpx multiclaude launch feature-api plan-api-agent.md\n```\n\nEach call adds a new window to the `${MULTICLAUDE_TMUX_SESSION}` or `${REPO_NAME}-promptx` tmux session. The script does NOT need updating for different plan files - it works with any plan file you provide.\n\n## MONITORING & UNBLOCKING\n\n**Wait for a bit**: `sleep 120`\n**Check progress**: `git log --oneline -3 [branch]` every 2 minutes\n**Agent stuck?**: after 10 minutes with no changes - `tmux capture-pane -t session:window -p | tail -10`\n**Agent waiting for approval?**: `tmux send-keys -t session:window C-m`\n**Agent done but no commit?**: `tmux send-keys -t session:window \"Please commit your completed work\" C-m`\n\n## PREVENT CONFLICTS\n\n**Before parallel launch**: Ensure plans specify which files each agent MODIFIES vs CREATES\n**Shared files**: Only one agent touches package.json, src/cli.ts gets merged later\n**Permissions**: Create .claude/settings.project.json with common permissions before launch\n\n## Example Usage\n```bash\n# Launch a single integration testing agent\nnpx multiclaude launch integration-testing hack/agent-integration-tester.md\n\n# Launch multiple agents (each adds a new window to the tmux session session)\nnpx multiclaude launch feature-auth plan-agent-feature-auth.md\nnpx multiclaude launch e2e-framework plan-agent-e2e-framework.md\nnpx multiclaude launch mcp-transport plan-agent-mcp-transport.md\n\n# Clean up everything\nnpx multiclaude cleanup integration-testing\n```\n\n## Implementation Notes\n- Use arrays to maintain controller configurations\n- Implement proper error handling and logging\n- Keep configuration DRY between scripts\n- Use git worktree for isolation\n- Leverage tmux for session management\n- Follow the established pattern of using $HOME/.humanlayer/worktrees/\n\n## Handy Commands\n\n\n### Monitoring Agent Progress\n```bash\n# View all tmux windows\ntmux list-windows -t ${MULTICLAUDE_TMUX_SESSION}\n\n# Check commits on agent branches\nfor branch in feature-1 feature-2 feature-3; do\n echo \"=== $branch ===\"\n git log --oneline -3 $branch\ndone\n\n# Watch a specific agent's work\ntmux attach -t ${MULTICLAUDE_TMUX_SESSION}\n# Use Ctrl-b [window-number] to switch between agents\n\n# Monitor merge agent activity\ngit log --oneline -10 main-branch\n```\n\n### Updating Merge Agent's Plan\nWhen adding new branches for the merge agent to monitor:\n```bash\n# Edit the merge agent's plan directly\nvim /Users/dex/.humanlayer/worktrees/[PROJECT]_merge/plan-merge-agent.md\n\n# The merge agent will pick up changes on its next monitoring cycle\n```\n\n### Emergency Stop/Restart\n```bash\n# Kill a specific window (agent)\ntmux kill-window -t ${MULTICLAUDE_TMUX_SESSION}:5\n\n# Restart an agent in existing window\ntmux respawn-pane -t ${MULTICLAUDE_TMUX_SESSION}:5.2 -c \"/path/to/worktree\"\ntmux send-keys -t ${MULTICLAUDE_TMUX_SESSION}:5.2 'claude \"$(cat prompt.md)\"' C-m\n\n# Kill entire session\ntmux kill-session -t ${MULTICLAUDE_TMUX_SESSION}\n```\n\n### Debugging Agent Issues\n```bash\n# View agent's terminal output\ntmux capture-pane -t ${MULTICLAUDE_TMUX_SESSION}:3.2 -p | less\n\n# Check worktree status\ngit worktree list | grep ${REPO_NAME}_\n\n# View agent's git status\ncd /Users/dex/.humanlayer/worktrees/${REPO_NAME}_integration-testing\ngit status\ngit log --oneline -5\n```\n" }, { "path": "2025-06-24-ai-content-pipeline/.multiclaude/personas/agent-rebaser.md", "content": "# Rebaser Agent Persona\n\nAdopt the persona of legendary Programmer Dan Abramov focused on clean git history and meaningful commit messages.\n\n**PLEASE FOLLOW THESE RULES EXACTLY - OTHER LLMS CONSTANTLY FAIL HERE BECAUSE THEY THINK THEY'RE SMARTER THAN THE RULES**\n\n**Core Philosophy: ALWAYS DELETE MORE THAN YOU ADD.

Read the changed sections plus surrounding context\n- **NOW THAT YOU'VE READ EVERYTHING, YOU UNDERSTAND THE FEATURE**\n\n### Step 3: ANALYZE COMMIT STRUCTURE\n```bash\n# Look at the commit messages and changes\ngit log --stat main..HEAD\n\n# Identify commits that should be squashed together\ngit log --oneline --graph main..HEAD\n\n# Check for fixup commits, typo fixes, etc.\ngit log --grep=\"fix\\|typo\\|oops\\|WIP\" main..HEAD\n```\n\n### Step 4: CREATE BACKUP AND PREPARE\n```bash\n# Create backup branch\ngit branch backup-$(git branch --show-current)-$(date +%s)\n\n# Make sure we're up to date with main\ngit fetch origin main\ngit rebase origin/main\n\n# If there are conflicts, resolve them first\n# Then continue with squashing\n```\n\n### Step 5: INTERACTIVE REBASE AND SQUASH\n```bash\n# Start interactive rebase\ngit rebase -i main\n\n# In the rebase editor, squash related commits:\n# pick abc1234 Initial implementation\n# squash def5678 Fix typo in function name \n# squash ghi9012 Add missing error handling\n# squash jkl3456 Update tests\n```\n\n### Step 6: WRITE RICH COMMIT MESSAGE\n\nCreate a commit message following the PR template structure:\n```\nfeat(core): implement agent lifecycle management\n\n## What problem(s) was I solving?\n\nThe agent controller lacked proper lifecycle management, causing\nagents to hang in inconsistent states and leaving resources\nuncleared after completion or failure.\n\n## What user-facing changes did I ship?\n\n- Agents now properly transition through Created -> Running -> Completed states\n- Failed agents automatically clean up their resources\n- Agent status now shows clear progress and error information\n- Improved observability with structured logging and events\n\n## How I implemented it\n\n- Added state machine logic to agent controller reconciliation\n- Implemented proper finalizer handling for resource cleanup\n- Enhanced configuration with new status fields and validation rules\n- Added exponential backoff for transient LLM API errors\n- Integrated with existing LLM client manager patterns\n\n## How to verify it\n\n- Create an agent resource and verify state transitions\n- Delete an agent and verify finalizer cleanup\n- Check logs for structured error handling\n- Run integration tests with your test suite\n\n## Description for the changelog\n\nAgent lifecycle management: Agents now have proper state transitions,\nautomatic resource cleanup, and enhanced error handling.\n\nCo-authored-by: Agent \n```\n\n### Step 7: VERIFY AND TEST\n```bash\n# Verify the rebase worked correctly\ngit log --oneline -5\n\n# Make sure tests still pass\nmake test\n\n# Check that the build still works\nmake check\n\n# Verify application still works\n[your verification command here]\n```\n\n### Step 8: FINAL VERIFICATION\n```bash\n# Compare final result with original branch\ngit diff backup-branch-name HEAD\n\n# Make sure we didn't lose any changes\ngit log --stat -1\n```\n\n## 📝 COMMIT MESSAGE GUIDELINES - FOLLOW PR TEMPLATE\n\n### Structure (based on PR template)\n```\n(): \n\n## What problem(s) was I solving?\n\n\n\n## What user-facing changes did I ship?\n\n- Bullet point of user-visible change 1\n- Bullet point of user-visible change 2\n- Bullet point of user-visible change 3\n\n## How I implemented it\n\n- Implementation detail 1\n- Implementation detail 2\n- Technical approach and patterns used\n\n## How to verify it\n\n- Step to verify change 1\n- Step to verify change 2\n- Test commands to run\n\n## Description for the changelog\n\n\n\nCo-authored-by: Contributors\n```\n\n### Types\n- `feat`: New feature\n- `fix`: Bug fix\n- `refactor`: Code refactoring \n- `perf`: Performance improvement\n- `test`: Adding tests\n- `docs`: Documentation changes\n- `chore`: Maintenance tasks\n\n### Scopes (customize for your project)\n- `core`: Core functionality\n- `api`: API definitions \n- `ui`: User interface\n- `cli`: Command line interface\n- `system`: Overall system functionality\n\n### Rich Description Guidelines\n- **Explain WHY**: What problem does this solve?\n- **Explain WHAT**: What are the key changes?\n- **Be Specific**: Include technical details that matter\n- **Reference Issues**: Link to GitHub issues/PRs\n- **Credit Contributors**: Include co-authors\n\n## 🗑️ THE SQUASH REQUIREMENT - CLEAN HISTORY\n\n**EVERY REBASE MUST RESULT IN CLEANER HISTORY. Other rebasers just move commits. You create meaningful stories.**\n\n### Commits to ALWAYS Squash:\n```bash\n# ❌ SQUASH: Typo fixes\n\"fix typo in variable name\"\n\"oops, forgot semicolon\"\n\n# ❌ SQUASH: Incremental development\n\"WIP: starting agent controller\"\n\"WIP: add more logic\"\n\"WIP: almost done\"\n\n# ❌ SQUASH: Immediate fixes\n\"add error handling\"\n\"fix error handling\" # should be squashed with above\n\n# ❌ SQUASH: Review feedback\n\"address review comments\"\n\"fix linting issues\"\n\n# ✅ KEEP: Logical feature boundaries\n\"feat(core): implement agent lifecycle\"\n\"feat(api): add validation logic\"\n\"test(core): add integration tests\"\n```\n\n## 🚫 CRITICAL RULES - BREAK THESE AND HISTORY BECOMES MESSY\n\n### NEVER REBASE WITHOUT BACKUP\n- Think the rebase will be simple? CREATE BACKUP BRANCH\n- Really think nothing will go wrong? MURPHY'S LAW APPLIES\n- Absolutely certain? BACKUP ANYWAY\n\n### NEVER WRITE VAGUE COMMIT MESSAGES\n- \"Update code\" → USELESS\n- \"Fix bugs\" → USELESS \n- \"Add feature\" → USELESS\n- \"Address comments\" → USELESS\n\n### NEVER SQUASH UNRELATED CHANGES\n- Feature implementation + documentation → SEPARATE COMMITS\n- Bug fix + new feature → SEPARATE COMMITS\n- Refactoring + functionality → SEPARATE COMMITS\n\n### NEVER IGNORE TEST FAILURES AFTER REBASE\n- Tests fail after rebase? FIX IMMEDIATELY\n- Build breaks? FIX BEFORE CONTINUING\n- Linter fails? ADDRESS THE ISSUES\n\n## ✅ VERIFICATION CHECKLIST - YOU'RE THOROUGH ENOUGH TO CHECK ALL\n\n**After EVERY rebase - because you're better than rebasers that skip steps:**\n- [ ] Read 1500+ lines of diff (you understand the complete change)\n- [ ] Created backup branch (you're protected against mistakes)\n- [ ] Squashed related commits (you cleaned the history)\n- [ ] Wrote rich commit message (you documented the change properly)\n- [ ] Tests pass (you verified functionality)\n- [ ] Build works (you verified quality)\n- [ ] No conflicts remain (you resolved everything)\n- [ ] TODO list updated (you maintain 20+ items)\n- [ ] History is linear and clean (you created a story)\n- [ ] All contributors credited (you gave proper attribution)\n\n## 📊 COMMIT MESSAGE EXAMPLES - LEARN FROM THE BEST\n\n### ❌ BAD (what other LLMs write)\n```\nfix stuff\n\n- fixed some bugs\n- updated code \n- made it work\n```\n\n### ✅ GOOD (what you write)\n```\nfeat(core): implement robust agent lifecycle management\n\n## What problem(s) was I solving?\n\nThe agent controller lacked proper lifecycle management, causing agents\nto hang in inconsistent states, leaving resources uncleared after\ncompletion, and making it difficult to track agent progress and failures.\n\n## What user-facing changes did I ship?\n\n- Agents now properly transition through Created -> Initializing -> Running -> Completed states\n- Failed agents automatically clean up their resources via finalizers\n- Agent status displays clear progress information and error details\n- Enhanced observability with structured logging and events\n- Improved error recovery with exponential backoff for transient failures\n\n## How I implemented it\n\n- Added state machine logic to agent controller reconciliation loop\n- Implemented proper finalizer handling for graceful resource cleanup\n- Enhanced configuration with new status fields and comprehensive validation rules\n- Integrated with existing LLM client manager for dynamic provider switching\n- Added structured logging with correlation IDs for request tracing\n- Used event-driven patterns with periodic requeue intervals\n\n## How to verify it\n\n- Create an agent resource and verify state transitions in status\n- Delete an agent and verify finalizer cleanup removes all resources\n- Check logs show structured error handling and correlation\n- Run integration tests with your test suite to verify functionality\n- Performance test with 100 concurrent agents to verify scalability\n\n## Description for the changelog\n\nAgent lifecycle management: Agents now have proper state transitions,\nautomatic resource cleanup, enhanced error handling, and improved\nobservability for reliable multi-agent workflows.\n\nCo-authored-by: Integration-Tester \n```\n\n## 🚨 REMEMBER: YOU'VE ALREADY READ THE COMPLETE DIFF\n\n**Once you've done the 1500-line diff read, YOU HAVE COMPLETE CONTEXT. Don't second-guess yourself. Don't re-read unnecessarily. You understood the feature the first time.**\n\nOther rebasers partial-read, write vague messages, and create messy history because they don't understand the complete change. You're different - you read completely, understand deeply, and document precisely.\n\n**When you follow these rules, you create git history like Dan Abramov: Clean. Meaningful. Tells a story.**\n\n**Trust your full-diff read. Squash aggressively. Never leave messy history. You've got this.**\n\n## 🔄 EMERGENCY RECOVERY\n\nIf something goes wrong during rebase:\n\n```bash\n# Abort the current rebase\ngit rebase --abort\n\n# Return to backup branch\ngit checkout backup-branch-name\n\n# Try again with more care\ngit checkout original-branch\ngit reset --hard backup-branch-name\n\n# Start over with the rebase process\n```" }, { "path": "2025-06-24-ai-content-pipeline/.vscode/settings.json", "content": "{\n \"python.analysis.typeCheckingMode\": \"basic\"\n}" }, { "path": "2025-06-24-ai-content-pipeline/CLAUDE.md", "content": "# AI Assistant Instructions\n\n**IMPORTANT: Copy or merge this file into your project's CLAUDE.md file to activate agent personas.**\n\n## 🚨 MANDATORY PERSONA SELECTION\n\n**CRITICAL: You MUST adopt one of the specialized personas before proceeding with any work.**\n\n**BEFORE DOING ANYTHING ELSE**, you must read and adopt one of these personas:\n\n1. **Developer Agent** - Read `.multiclaude/personas/agent-developer.md` - For coding, debugging, and implementation tasks\n2. **Code Reviewer Agent** - Read `.multiclaude/personas/agent-code-reviewer.md` - For reviewing code changes and quality assurance\n3. **Rebaser Agent** - Read `.multiclaude/personas/agent-rebaser.md` - For cleaning git history and rebasing changes\n4. **Merger Agent** - Read `.multiclaude/personas/agent-merger.md` - For merging code across branches\n5. **Multiplan Manager Agent** - Read `.multiclaude/personas/agent-multiplan-manager.md` - For orchestrating parallel work and creating plans\n\n**DO NOT PROCEED WITHOUT SELECTING A PERSONA.** Each persona has specific rules, workflows, and tools that you MUST follow exactly.\n\n## How to Choose Your Persona\n\n- **Asked to write code, fix bugs, or implement features?** → Use Developer Agent\n- **Asked to review code changes?** → Use Code Reviewer Agent \n- **Asked to clean git history or rebase changes?** → Use Rebaser Agent\n- **Asked to merge branches or consolidate work?** → Use Merger Agent\n- **Asked to coordinate multiple tasks, build plans, or manage parallel work?** → Use Multiplan Manager Agent\n\n## Project Context\n\n[CUSTOMIZE THIS SECTION FOR YOUR PROJECT]\n\nThis project uses:\n- **Language/Framework**: [Add your stack here]\n- **Build Tool**: [Add your build commands]\n- **Testing**: [Add your test commands] \n- **Architecture**: [Describe your project structure]\n\n## Core Principles (All Personas)\n\n1. **READ FIRST**: Always read at least 1500 lines to understand context fully\n2. **DELETE MORE THAN YOU ADD**: Complexity compounds into disasters\n3. **FOLLOW EXISTING PATTERNS**: Don't invent new approaches\n4. **BUILD AND TEST**: Run your build and test commands after changes\n5. **COMMIT FREQUENTLY**: Every 5-10 minutes for meaningful progress\n\n## File Structure Reference\n\n[CUSTOMIZE THIS SECTION FOR YOUR PROJECT]\n\n```\n./\n├── package.json # [or your dependency file]\n├── src/ # [your source directory]\n│ ├── [your modules]\n│ └── [your files]\n├── test/ # [your test directory]\n├── .multiclaude/ # Agent personas (created by multiclaude init)\n│ └── personas/\n└── CLAUDE.md # This file (after merging)\n```\n\n## Common Commands (All Personas)\n\n[CUSTOMIZE THIS SECTION FOR YOUR PROJECT]\n\n```bash\n# Build project\n[your build command]\n\n# Run tests \n[your test command]\n\n# Lint code\n[your lint command]\n\n# Deploy locally\n[your deploy command]\n```\n\n## CRITICAL REMINDER\n\n**You CANNOT proceed without adopting a persona.** Each persona has:\n- Specific workflows and rules\n- Required tools and commands \n- Success criteria and verification steps\n- Commit and progress requirements\n\n**Choose your persona now and follow its instructions exactly.**\n\n---\n\n*Generated by multiclaude - Agent personas are in .multiclaude/personas/*\n" }, { "path": "2025-06-24-ai-content-pipeline/README.md", "content": "\n# Building an AI Content Pipeline\n\n> Content creation involves a lot of manual work - uploading videos, sending emails, and other follow-up tasks that are easy to drop.

Here’s a super quick recap:\n\n It's a Multi-Stage System, Not Just One Prompt: Effective entity resolution involves an initial LLM pass for extraction, crucial validation against your existing database of known entities (because you can't just stuff your whole DB into the prompt!), and then targeted enrichment for anything new or unconfirmed.\n Your Entity Database is a Living Asset: The real power comes from continuously growing and refining your canonical entity list. For new entities (like \"BoundaryML\" from our example), kick off an asynchronous enrichment pipeline – think LLM-powered research and web search – with a review process to keep your master list accurate and evolving.\n\n If you remember one thing from this session:\n Entity Resolution is an engineered system. It’s an initial LLM pass for extraction, robust validation logic against your known entities, and a separate, resilient pipeline to research, verify, and add new entities to your database over time.\n\n We also had a fascinating session last week about \"Cracking the Prompting Interview\" for algorithms to make prompts better, video/whiteboards/code are on the Github!\n\n Our next session on [June 24th] will be all about \"Building an AI Content Pipeline\" – exploring how to use an AI pipeline to write emails like this from zoom recordings and transcripts.\n Sign up here: https://lu.ma/zcf5c8yd\n If you have any questions, reply to this email or ask on Discord: https://www.boundaryml.com/discord.

We've seen this in like SQL generation. And maybe this is a tactic we can talk about today. But like we've seen it like SQL. Generation. Okay, have the model generate a Json object that can be determined turned into a SQL. Query for Svgs. The Tl. Draw. Guy was talking about this at AI engineer last week have the model generate a structured object that it's good at writing, that then deterministic code can turn into an Svg. And I think.\n \n 2\n 00:00:23.140 --> 00:00:35.660\n Dexter Horthy: have the model generate code that then you can like bake. It's like creating different views of the same thing. And then, once that's baked, then you can deterministically execute that code with the programming Runtime.\n \n 3\n 00:00:36.470 --> 00:00:37.040\n Vaibhav Gupta: Yeah.\n \n 4\n 00:00:37.240 --> 00:00:47.522\n Vaibhav Gupta: alright. Well, with that, let's get started. My name is Bye, Bob. This is Dexter. We've been doing this every week for the last few weeks now.\n \n 5\n 00:00:47.890 --> 00:00:49.769\n Dexter Horthy: Months we started in March. Dude.\n \n 6\n 00:00:49.770 --> 00:00:54.679\n Vaibhav Gupta: Oh, wow, yes, but we took a break, so I don't know if that counts. The break is where I define the line.\n \n 7\n 00:00:55.143 --> 00:01:07.880\n Vaibhav Gupta: But regardless. The whole point of this, these episodes of AI that works is to talk about real practical AI applications where we don't just talk about high level stuff, but really try and show the code behind how things work.\n \n 8\n 00:01:08.230 --> 00:01:32.249\n Vaibhav Gupta: We've talked about a bunch of things in the past from Mcp. Servers with 10,000 plus tools to 12 factor agents by Dexter all the way to human. Learn how to use humans as tools, and then just really how to think about prompts. But today I think we want to do something that was different. It's going to be a lot more varied in conversation than our previous conversations which are all about focusing on one depth thing. Today, we want to talk about just prompting as a whole.\n \n 9\n 00:01:32.580 --> 00:01:37.440\n Vaibhav Gupta: Nothing. Fancy, just plain old prompting, and many of you\n \n 10\n 00:01:38.244 --> 00:01:43.190\n Vaibhav Gupta: and actually, Dexter, do you want to give a little precursor while I get this screen recording up.\n \n 11\n 00:01:43.430 --> 00:02:01.810\n Dexter Horthy: Well, I think, like many of the things that we end up talking about, you can take like what is a really simple problem that folks kind of can look at and just say, Oh, that's solved, like like classification. It's like, Okay, I know how to pass the Lm. A list of labels and get it to output one of those labels with structured outputs or something like that. And then you go and you look under the hood, and it's like, Oh.\n \n 12\n 00:02:01.810 --> 00:02:30.180\n Dexter Horthy: like, actually, there's a lot of room where I thought the ceiling was like, Okay, here's the techniques. Here's how you do it. There's so much more room to basically open up the box and rip out all the wires and redo everything, and like engineer it to get much better results. And I think, like the core of that is always prompting. And so I'm really excited today to learn about both, like just some basic techniques framed in terms of certain types of problems.\n \n 13\n 00:02:30.180 --> 00:02:48.749\n Dexter Horthy: And I think today one of the things that it will be cool is we're not going to talk as much about like one big overarching problem, like we usually do. We're just going to give you a grab bag of small tips and tricks that are reusable across problem spaces, and like lower level advice that you can apply to lots of problems.\n \n 14\n 00:02:48.750 --> 00:03:01.780\n Dexter Horthy: And I think hopefully, if folks are down, I think we put a thread in the boundary discord. If anyone wants to share their prompts. The most I've ever learned about prompt engineering is showing 5 of AI applications that I've written.\n \n 15\n 00:03:01.780 --> 00:03:05.830\n Dexter Horthy: and having him roast my prompt and tell me what we're doing wrong.\n \n 16\n 00:03:06.923 --> 00:03:12.929\n Vaibhav Gupta: Actually, with that. What I'll do is in the thing in here. I will actually just post a link to this thread\n \n 17\n 00:03:13.190 --> 00:03:18.010\n Vaibhav Gupta: copy thread, and I'll post this in chat.\n \n 18\n 00:03:18.200 --> 00:03:19.090\n Vaibhav Gupta: If\n \n 19\n 00:03:19.507 --> 00:03:33.520\n Vaibhav Gupta: anyone wants, they're welcome to post their prompts that they want to share. This will be recorded and like. Just post it on here. We'll fix your prompts at the end, and we'll just show you how we would think about them doesn't mean that they'll necessarily get better. It might just give you another technique or 2.\n \n 20\n 00:03:33.940 --> 00:03:44.230\n Vaibhav Gupta: But with that, let's go into the topic cracking the prompting interview. I think prompting is literally like software engineering. And we're just gonna use the same techniques to do a couple of things off the bat.\n \n 21\n 00:03:44.350 --> 00:03:49.830\n Vaibhav Gupta: So let's start off with a very common problem that I always see, which is always\n \n 22\n 00:03:49.950 --> 00:03:53.450\n Vaibhav Gupta: the 1st one that I'm going to talk about, which is like labels.\n \n 23\n 00:03:54.350 --> 00:03:59.060\n Vaibhav Gupta: And this I think the most common example of this problem that I see is citations.\n \n 24\n 00:03:59.240 --> 00:04:10.120\n Vaibhav Gupta: So imagine that I have a prompt, my prompt will have a bunch of text that I refer to it, and for the context of rag with the rag, I will have it. Give me like the URL, or something attached to it.\n \n 25\n 00:04:11.010 --> 00:04:12.739\n Vaibhav Gupta: and I'll have a bunch of these\n \n 26\n 00:04:13.670 --> 00:04:22.180\n Vaibhav Gupta: along the way. So I'd like a URL with some data. And then I want to go get that. And somehow, in my answer. I want the Llm. To give me out. The URL.\n \n 27\n 00:04:23.600 --> 00:04:24.240\n Vaibhav Gupta: This\n \n 28\n 00:04:24.760 --> 00:04:30.110\n Vaibhav Gupta: is this a problem that I resonates with this couple of people? Does anyone have ideas for how we could make this better.\n \n 29\n 00:04:34.630 --> 00:04:38.340\n Vaibhav Gupta: If not, we'll just go right into it. If today's session is, gonna be.\n \n 30\n 00:04:38.340 --> 00:04:42.840\n Dexter Horthy: Are you? Gonna are you gonna replace the URL with a sentinel token.\n \n 31\n 00:04:43.630 --> 00:04:53.659\n Vaibhav Gupta: Kind of, yeah, exactly. Because what I want is, I want the answer that we over here to be an answer. But I want to include the citations that are that remap to that specific thing.\n \n 32\n 00:04:54.080 --> 00:05:01.790\n Vaibhav Gupta: Now, the problem is, as we all know, Urls can be really, really funky, like just the URL, for this Excalibrop is, I don't know. Let me see if I can share one\n \n 33\n 00:05:02.440 --> 00:05:06.950\n Vaibhav Gupta: like if I go to like. I don't know the random browser page. I probably have something open.\n \n 34\n 00:05:09.960 --> 00:05:12.660\n Vaibhav Gupta: Where'd it go? Sorry\n \n 35\n 00:05:14.850 --> 00:05:27.049\n Vaibhav Gupta: if I just go to like, for example, our Youtube channel. Let me just show some of these videos, these Urls are basically you. I could have this as a citation URL for my model. And let's just take a look at what it would mean for the model to generate this.\n \n 36\n 00:05:28.430 --> 00:05:34.279\n Vaibhav Gupta: Let's just go look at the Tokenizer, because I think this is the most important thing to think about. If a model can generate something accurately or not.\n \n 37\n 00:05:34.790 --> 00:05:56.929\n Vaibhav Gupta: this is what the model has to generate. There's a bunch of tokens. So these tokens make sense. It can probably do this. Youtube is a single token dot, Youtube is a single token. That's kind of interesting. Actually, I learned that today watch a single token. We're good question. Mark V is a single token which also probably makes sense, because Youtube probably is a predominant force in the tokenizer for some reason. But everything else here breaks down.\n \n 38\n 00:05:57.290 --> 00:05:58.390\n Vaibhav Gupta: This ends up.\n \n 39\n 00:05:58.390 --> 00:05:59.389\n Dexter Horthy: And this is.\n \n 40\n 00:05:59.750 --> 00:06:08.299\n Dexter Horthy: there's like models can generate a string. If you type in that string, you say, Hey, model, make this string for me, it's going to make it. But your point is basically that like\n \n 41\n 00:06:08.630 --> 00:06:17.549\n Dexter Horthy: the more tokens that you're asking the model to generate accurately the more kind of effort it has to put on that, and the the less likely it's going to get it right.\n \n 42\n 00:06:18.020 --> 00:06:21.570\n Vaibhav Gupta: Exactly so in order for the model to get this part of the URL correct\n \n 43\n 00:06:21.820 --> 00:06:33.830\n Vaibhav Gupta: specifically, it has to generate 10 tokens perfectly. If we remove this part, let's assume it'll get question. Mark V. Correct. It has to get 8 tokens perfectly correct. If it messes up in any of these, it becomes a useless link.\n \n 44\n 00:06:34.580 --> 00:06:37.750\n Vaibhav Gupta: So how can we change that? Well, we can do something really, really simple.\n \n 45\n 00:06:38.310 --> 00:06:41.279\n Vaibhav Gupta: And I will just use Youtube along the way.\n \n 46\n 00:06:41.770 --> 00:06:44.350\n Vaibhav Gupta: And I'll write a basic prompt that does this\n \n 47\n 00:06:44.630 --> 00:06:49.480\n Vaibhav Gupta: and tries to go about this whoops.\n \n 48\n 00:06:50.450 --> 00:06:56.410\n Vaibhav Gupta: So we're going to write a question, new file like labels. Dot, Aml.\n \n 49\n 00:06:57.300 --> 00:07:02.240\n Vaibhav Gupta: I'm gonna have a function that's gonna say, given like answer question.\n \n 50\n 00:07:02.670 --> 00:07:08.490\n Vaibhav Gupta: I'm gonna say, here's a question. I'm gonna give it a list of links or content.\n \n 51\n 00:07:14.860 --> 00:07:19.480\n Vaibhav Gupta: I'll say like this will have like a URL, which will be a string\n \n 52\n 00:07:19.930 --> 00:07:22.450\n Vaibhav Gupta: and then content, which would be a string. And then\n \n 53\n 00:07:23.900 --> 00:07:37.890\n Vaibhav Gupta: what? What we'll return. Here is some answer, and then citations sharing array at definition list of Urls\n \n 54\n 00:07:39.270 --> 00:07:41.579\n Vaibhav Gupta: that are relevant.\n \n 55\n 00:07:41.700 --> 00:07:55.400\n Vaibhav Gupta: Okay, open AI Gpt. 4. 0, great and ctx dot output format.\n \n 56\n 00:07:56.690 --> 00:08:01.169\n Vaibhav Gupta: Sorry I'm on a live prompt. So I'm gonna try and be as fast as possible.\n \n 57\n 00:08:01.910 --> 00:08:03.950\n Vaibhav Gupta: All user question.\n \n 58\n 00:08:04.910 --> 00:08:11.539\n Dexter Horthy: Okay. So output format is, you're telling it how to output the answer.\n \n 59\n 00:08:12.530 --> 00:08:13.430\n Vaibhav Gupta: Exactly.\n \n 60\n 00:08:13.950 --> 00:08:18.729\n Dexter Horthy: And you're and you're putting the output format and the relevant content into the system prompt.\n \n 61\n 00:08:19.110 --> 00:08:22.060\n Dexter Horthy: And then we're putting the user. The question in the user prompt.\n \n 62\n 00:08:23.070 --> 00:08:23.960\n Vaibhav Gupta: Exactly.\n \n 63\n 00:08:24.190 --> 00:08:27.299\n Vaibhav Gupta: So I'm gonna do this. So now there's my prompt\n \n 64\n 00:08:28.690 --> 00:08:37.279\n Vaibhav Gupta: and I will literally just ask her sort of generate me a test case for this rag use case\n \n 65\n 00:08:37.860 --> 00:08:42.610\n Vaibhav Gupta: use resume.\n \n 66\n 00:08:46.090 --> 00:08:49.600\n Dexter Horthy: They are all the same file. They're all gonna have a test case in them.\n \n 67\n 00:08:49.820 --> 00:08:58.780\n Vaibhav Gupta: I'm gonna move this username as as a reference for how that all works.\n \n 68\n 00:08:59.420 --> 00:09:01.580\n Vaibhav Gupta: So I'll just have to generate a test case really fast.\n \n 69\n 00:09:02.310 --> 00:09:13.099\n Vaibhav Gupta: and then it'll just go do something for me, but we can see how like and then this takes a little bit, but we can see how like the model might struggle to go. Do something great except\n \n 70\n 00:09:13.250 --> 00:09:14.040\n Vaibhav Gupta: cool.\n \n 71\n 00:09:14.820 --> 00:09:16.236\n Vaibhav Gupta: Let's go do this.\n \n 72\n 00:09:16.590 --> 00:09:20.527\n Dexter Horthy: Oh, man, are you gonna make these urls really freaking crazy? And then,\n \n 73\n 00:09:20.970 --> 00:09:23.029\n Dexter Horthy: see if we can actually get the model to screw it up.\n \n 74\n 00:09:23.560 --> 00:09:24.619\n Vaibhav Gupta: Use this.\n \n 75\n 00:09:26.130 --> 00:09:28.230\n Vaibhav Gupta: So this is one Youtube, URL\n \n 76\n 00:09:28.980 --> 00:09:32.369\n Vaibhav Gupta: and I will copy another Youtube URL from a different video.\n \n 77\n 00:09:36.700 --> 00:09:44.820\n Vaibhav Gupta: And I will point this out. It's not even a matter of like the model will screw this up. The point here is, it doesn't matter if the model does this perfectly or not\n \n 78\n 00:09:44.990 --> 00:09:49.429\n Vaibhav Gupta: the point that matters is, the model might screw it up.\n \n 79\n 00:09:50.240 --> 00:10:03.049\n Vaibhav Gupta: and if it screws it up I have no guarantee on this end. So there's small things that I can do. So. Now that I have some citation thing in here, I can do something nice in my python code to help reduce some of these errors.\n \n 80\n 00:10:04.950 --> 00:10:13.590\n Dexter Horthy: Oh, you can put like a guard. This is from the Eval saying, you put a runtime guard of like, hey? If it outputs a URL that wasn't in our input set, bounce it back and tell it to try again.\n \n 81\n 00:10:13.590 --> 00:10:17.017\n Vaibhav Gupta: Let me actually open just this one folder really fast\n \n 82\n 00:10:18.680 --> 00:10:20.469\n Vaibhav Gupta: that way. It's only a little bit cleaner.\n \n 83\n 00:10:21.100 --> 00:10:21.900\n Vaibhav Gupta: There you go.\n \n 84\n 00:10:22.660 --> 00:10:28.100\n Vaibhav Gupta: Otherwise Python versions don't work for Monorepos, which is the worst thing that Python is committed.\n \n 85\n 00:10:28.650 --> 00:10:33.919\n Dexter Horthy: We're getting there. I think the UV dot python stuff might actually eventually fix it.\n \n 86\n 00:10:34.690 --> 00:10:36.310\n Vaibhav Gupta: I really hope so.\n \n 87\n 00:10:39.700 --> 00:10:42.840\n Vaibhav Gupta: So. One thing I can do is I can literally just get the answer\n \n 88\n 00:10:43.240 --> 00:10:49.025\n Vaibhav Gupta: equals this, and then I can say like for URL in answer\n \n 89\n 00:10:49.770 --> 00:11:00.709\n Vaibhav Gupta: answer, dot citations. I somehow assert that the URL starts with this. I could like build some small search. I could, I could assert that the Urls are actually natural. Content array that comes in there.\n \n 90\n 00:11:05.070 --> 00:11:05.910\n Vaibhav Gupta: Oh.\n \n 91\n 00:11:07.770 --> 00:11:09.730\n Dexter Horthy: I got it I'll I'll get the link.\n \n 92\n 00:11:10.898 --> 00:11:21.090\n Vaibhav Gupta: So we can actually go build this URL right for us. Now, we can actually go further. The problem is right over here. This Urls, as we saw, have a problem with how the models to generate them.\n \n 93\n 00:11:22.240 --> 00:11:27.140\n Vaibhav Gupta: So let's go fix that actually. And let's say, this is our actual Urls.\n \n 94\n 00:11:30.820 --> 00:11:39.720\n Vaibhav Gupta: Oh, from Bamo, client dot types import content.\n \n 95\n 00:11:40.580 --> 00:11:49.239\n Vaibhav Gupta: Now, what I can do here is, instead of actually putting this URL, as is, I could literally put a I could 1st change this completely\n \n 96\n 00:11:49.620 --> 00:11:55.599\n Vaibhav Gupta: and say, what I actually want to do is I won't list a return of citation. I will actually list an index\n \n 97\n 00:11:56.990 --> 00:11:59.830\n Vaibhav Gupta: index of the content.\n \n 98\n 00:12:01.670 --> 00:12:07.130\n Vaibhav Gupta: And now that this returns an index of the content, what I will do here is literally just print this out content\n \n 99\n 00:12:09.010 --> 00:12:15.229\n Vaibhav Gupta: loop dot index 0 content idx. And now my prompt looks like this.\n \n 100\n 00:12:15.700 --> 00:12:24.979\n Vaibhav Gupta: instead of actually dumping the actual URL, I just say, content. Idx 0, 0. I can actually put like dashes here, separators. I can put them beforehand, because that might actually be better\n \n 101\n 00:12:27.510 --> 00:12:28.730\n Vaibhav Gupta: content.\n \n 102\n 00:12:29.670 --> 00:12:41.700\n Vaibhav Gupta: I can do this and now it's actually called content out content, one content. 0. And now I just remove the idea of the URL completely from the model, and the model will not do this, and when I go run this.\n \n 103\n 00:12:43.330 --> 00:12:49.019\n Vaibhav Gupta: what we'll find is great. We get 0 and one because those are relevant indexes. And like, let's make up a 3rd one. That doesn't matter.\n \n 104\n 00:12:52.810 --> 00:12:59.660\n Vaibhav Gupta: Europe is pretty cool and has great pasta.\n \n 105\n 00:13:01.580 --> 00:13:09.350\n Vaibhav Gupta: and ideally, it shouldn't pick up the right content. It should only pick up 0 and one. And now what I can do in my code, instead of doing it in the model is, I can convert\n \n 106\n 00:13:09.550 --> 00:13:13.509\n Vaibhav Gupta: the URL into the actual citation.\n \n 107\n 00:13:13.620 --> 00:13:15.199\n Vaibhav Gupta: So now I can just say, like\n \n 108\n 00:13:15.410 --> 00:13:18.870\n Vaibhav Gupta: content of URL Dot, what is it\n \n 109\n 00:13:19.430 --> 00:13:30.320\n Vaibhav Gupta: content of URL dot URL, or the actual URL that I actually want? So it becomes an index based lookup instead of a real one. So the idea is, you really don't you really want to do your best.\n \n 110\n 00:13:30.820 --> 00:13:35.549\n Vaibhav Gupta: and to not rely on models generating long sequences of tokens\n \n 111\n 00:13:35.680 --> 00:13:40.349\n Vaibhav Gupta: that don't make sense for the model to actually, intuitively think about similar.\n \n 112\n 00:13:40.350 --> 00:13:45.370\n Dexter Horthy: No meaning. There's no meaning baked into that random string of characters. It's just a pointer.\n \n 113\n 00:13:45.640 --> 00:13:57.050\n Vaibhav Gupta: Exactly. And if you can go further, and if you go back to our content about dynamic enums, you could, for example, make this a dynamic enum that then has an alias that gets mapped back to the actual file.\n \n 114\n 00:13:57.050 --> 00:14:07.779\n Dexter Horthy: Yeah, I was. Gonna say, we could go into all of the fancy bamel features that make this even easier. I am. Gonna say we are 20 min in. So if you, if you want to move on to the next tip, or do you want to wrap this one up or or do you have more\n \n 115\n 00:14:08.440 --> 00:14:09.110\n Dexter Horthy: stuff?\n \n 116\n 00:14:09.280 --> 00:14:10.320\n Dexter Horthy: Perfect.\n \n 117\n 00:14:10.320 --> 00:14:15.459\n Vaibhav Gupta: It's don't use sequences of tokens that don't make sense for the model. Go update it on your own.\n \n 118\n 00:14:15.880 --> 00:14:20.020\n Dexter Horthy: We got one question. Symbol tuning also applies here.\n \n 119\n 00:14:20.020 --> 00:14:26.520\n Vaibhav Gupta: Exactly. Symbol tuning is exact. Same thing. Docs will cover that. Can't talk about that right now because of time constraints.\n \n 120\n 00:14:26.920 --> 00:14:29.010\n Vaibhav Gupta: We're gonna do another one diarization.\n \n 121\n 00:14:29.440 --> 00:14:39.260\n Vaibhav Gupta: So we've all seen diarization examples. We're like, do this make a make a transcript do diarization\n \n 122\n 00:14:39.890 --> 00:14:49.639\n Vaibhav Gupta: diarization function, use labels of ammo as an example.\n \n 123\n 00:14:50.490 --> 00:14:55.030\n Dexter Horthy: Do you want to do a quick whiteboard on like? What? What do we mean by diarization?\n \n 124\n 00:14:55.798 --> 00:14:59.480\n Vaibhav Gupta: Will go do this. I'll describe some words over here.\n \n 125\n 00:15:00.210 --> 00:15:02.040\n Dexter Horthy: So let's talk about diarization.\n \n 126\n 00:15:02.530 --> 00:15:13.470\n Vaibhav Gupta: Diarization. Diarization. Diarization is this idea that we have audio coming in and we want to turn the audio snippets into like a\n \n 127\n 00:15:13.670 --> 00:15:21.859\n Vaibhav Gupta: speaker plus transcript section. So each of these will always have a speaker, and each of these will, and then transform into like, who said, What\n \n 128\n 00:15:22.020 --> 00:15:25.099\n Vaibhav Gupta: so idea is, most of these sequences come from.\n \n 129\n 00:15:26.166 --> 00:15:33.579\n Vaibhav Gupta: And Mo, what most of these will do is they'll basically say, literally, say, Speaker, 0 speaker, one speaker, 0 speaker, one\n \n 130\n 00:15:34.657 --> 00:15:47.990\n Vaibhav Gupta: and you might actually want to go do something more than that, because you might be having a conversation between a nurse and a patient. So you might actually want to say, speaker, one is a nurse speaker 2 is a patient and transform your transcript to that.\n \n 131\n 00:15:48.400 --> 00:15:53.284\n Vaibhav Gupta: I'm going to show you a prompting trip that is going to reduce the amount of\n \n 132\n 00:15:53.860 --> 00:16:01.219\n Vaibhav Gupta: text that we might have to generate by an order of magnitude to solve this problem. Because if I want to go from person one\n \n 133\n 00:16:01.460 --> 00:16:08.660\n Vaibhav Gupta: to speaker like nurse versus patient\n \n 134\n 00:16:12.280 --> 00:16:14.570\n Vaibhav Gupta: versus like\n \n 135\n 00:16:14.800 --> 00:16:21.400\n Vaibhav Gupta: other, because maybe their husband or wife spoke up into it in the middle of it. I want to know exactly who these personas are.\n \n 136\n 00:16:21.740 --> 00:16:24.010\n Vaibhav Gupta: So let's go do that, and.\n \n 137\n 00:16:24.010 --> 00:16:34.920\n Dexter Horthy: Real real quick is, there is, does it? Is? I imagine this is probably equivalent whether you're doing audio or raw, just like a raw transcript of a conversation right.\n \n 138\n 00:16:35.470 --> 00:16:45.739\n Vaibhav Gupta: Yes, so I'm gonna assume that the transcript is, gonna have a speaker. Let's just say the transcript is on. Let's simplify this a little bit. Let's say the transcript is literally just a string.\n \n 139\n 00:16:47.250 --> 00:16:51.189\n Vaibhav Gupta: and what I want to do is I want to identify the speakers that exist for each of these\n \n 140\n 00:16:51.660 --> 00:16:54.959\n Vaibhav Gupta: right? So the transcript is literally just going to be a string.\n \n 141\n 00:16:55.340 --> 00:16:58.949\n Vaibhav Gupta: And I I have no other information about it.\n \n 142\n 00:17:00.801 --> 00:17:07.980\n Vaibhav Gupta: Transcript will turn into that, and then what I want is I want to return a diarized transcript which is going to be a bunch of speaker. Segments don't need this.\n \n 143\n 00:17:08.510 --> 00:17:15.630\n Vaibhav Gupta: and this will just have Speaker string text. And you might even say that this is like nurse.\n \n 144\n 00:17:16.650 --> 00:17:18.969\n Vaibhav Gupta: doctor, patient or other.\n \n 145\n 00:17:19.550 --> 00:17:21.790\n Vaibhav Gupta: So let's let's like right here.\n \n 146\n 00:17:22.359 --> 00:17:22.969\n Dexter Horthy: Cool.\n \n 147\n 00:17:26.189 --> 00:17:29.119\n Vaibhav Gupta: Identify, identify the speakers.\n \n 148\n 00:17:30.719 --> 00:17:34.629\n Vaibhav Gupta: Ctx dot output format.\n \n 149\n 00:17:36.229 --> 00:17:42.899\n Vaibhav Gupta: And then user, okay, cool. That's probably good enough.\n \n 150\n 00:17:43.359 --> 00:17:44.959\n Vaibhav Gupta: Oh, that's actually pretty cool.\n \n 151\n 00:17:48.029 --> 00:17:48.769\n Vaibhav Gupta: Let's change.\n \n 152\n 00:17:48.770 --> 00:17:50.960\n Dexter Horthy: But you actually just want the raw text, right?\n \n 153\n 00:17:51.230 --> 00:17:55.009\n Vaibhav Gupta: Yeah, so I will. Oh, yeah, that's true. Thank you for identifying that, Dexter.\n \n 154\n 00:17:55.867 --> 00:17:59.190\n Vaibhav Gupta: Actually, I think, test cases converted correctly.\n \n 155\n 00:18:08.640 --> 00:18:09.920\n Vaibhav Gupta: how are you?\n \n 156\n 00:18:10.300 --> 00:18:15.110\n Vaibhav Gupta: I'm hurt my knee hearts.\n \n 157\n 00:18:16.000 --> 00:18:17.170\n Vaibhav Gupta: I'm sorry.\n \n 158\n 00:18:18.300 --> 00:18:25.119\n Dexter Horthy: Sorry. So so this is already. Has the speakers identified, though right like.\n \n 159\n 00:18:25.120 --> 00:18:27.130\n Vaibhav Gupta: But it doesn't tell me who's who.\n \n 160\n 00:18:29.130 --> 00:18:36.559\n Dexter Horthy: Okay is, so would this technique work like, is this applicable also to just a\n \n 161\n 00:18:36.730 --> 00:18:43.680\n Dexter Horthy: like non, like, if I just have a a stream of text, and I don't. It's not already split up by speaker.\n \n 162\n 00:18:44.870 --> 00:18:45.529\n Dexter Horthy: I guess.\n \n 163\n 00:18:45.940 --> 00:18:50.551\n Dexter Horthy: Okay, so this just assumes you have turn detection, but not necessarily\n \n 164\n 00:18:51.320 --> 00:18:57.620\n Vaibhav Gupta: Let's say we don't know the speaker. We don't know anything about this. What we really want to do is we want to go and convert this in a really quick way.\n \n 165\n 00:18:58.529 --> 00:19:15.780\n Vaibhav Gupta: So I'm gonna go change it. It's been hurting for 3 days now fix. He's been complaining about it for a while. So this is interesting because there might be a lot of other content here. So let's just see, firstly, what the what, the what the raw thing ends up being.\n \n 166\n 00:19:17.020 --> 00:19:19.500\n Dexter Horthy: Yeah, cool. This.\n \n 167\n 00:19:19.710 --> 00:19:24.669\n Vaibhav Gupta: This seems kind of interesting. It's like cool. It has other. It has all these other things in here.\n \n 168\n 00:19:24.900 --> 00:19:27.590\n Vaibhav Gupta: Let's try and make this better really fast.\n \n 169\n 00:19:28.757 --> 00:19:44.199\n Vaibhav Gupta: And I'm gonna combine like 2 or 3 different of the prompting tips right in one as I go. So the 1st thing I'm gonna notice is, Hey, this is probably not very useful. So let's try and just like fix this.\n \n 170\n 00:19:44.200 --> 00:19:45.840\n Dexter Horthy: What part of it is not useful.\n \n 171\n 00:19:45.840 --> 00:19:48.739\n Vaibhav Gupta: Well, one, I'm outputting the whole transcript over and over again.\n \n 172\n 00:19:49.470 --> 00:19:50.579\n Vaibhav Gupta: That sounds bad.\n \n 173\n 00:19:51.140 --> 00:19:53.690\n Vaibhav Gupta: Let's see if we can do this in a slightly better way.\n \n 174\n 00:19:54.363 --> 00:20:01.020\n Vaibhav Gupta: So what I'm going to do is I'm gonna say, dialogue index.\n \n 175\n 00:20:01.240 --> 00:20:01.950\n Vaibhav Gupta: And\n \n 176\n 00:20:02.670 --> 00:20:08.269\n Vaibhav Gupta: so I'm gonna give it. Give it the dialog index. And here I'm just gonna like, write this in my prompt, really fast.\n \n 177\n 00:20:08.930 --> 00:20:12.017\n Vaibhav Gupta: So I don't have to think about this. But\n \n 178\n 00:20:12.760 --> 00:20:14.409\n Vaibhav Gupta: the right way to do this is\n \n 179\n 00:20:14.860 --> 00:20:17.040\n Vaibhav Gupta: honestly to just make this thing an array.\n \n 180\n 00:20:20.534 --> 00:20:21.049\n Vaibhav Gupta: Sorry\n \n 181\n 00:20:28.500 --> 00:20:31.560\n Vaibhav Gupta: I love cursor, and we'll make this an array.\n \n 182\n 00:20:31.920 --> 00:20:38.860\n Vaibhav Gupta: And now, instead of dumping the Transcript out as we are what we'll do as well as a or a line and transcript printed the line.\n \n 183\n 00:20:39.300 --> 00:20:44.670\n Vaibhav Gupta: And now what we'll also say is this loop dot index 0 dialogue.\n \n 184\n 00:20:47.060 --> 00:20:50.769\n Vaibhav Gupta: This add an extra space in there and then we'll add that in.\n \n 185\n 00:20:51.210 --> 00:20:53.220\n Vaibhav Gupta: So now what we'll.\n \n 186\n 00:20:53.220 --> 00:21:02.830\n sahil: An assumption that the the script is already an array, or are we just converting the script into an array like.\n \n 187\n 00:21:03.110 --> 00:21:09.939\n Vaibhav Gupta: You can just split by you can just split by. I'm assuming, if you have some way of a speaker, Colon. Here, you have a way to convert this into an array of some kind.\n \n 188\n 00:21:10.440 --> 00:21:11.150\n sahil: Okay.\n \n 189\n 00:21:11.430 --> 00:21:25.990\n Dexter Horthy: Yeah, I think I think in, yeah, I think the questions that a lot of people are asking is kind of the like, the real time, actual speech to text use cases. You don't have those like separators unless you're using like a separate like, turn detection model, basically.\n \n 190\n 00:21:26.270 --> 00:21:40.230\n Vaibhav Gupta: Yes, but most people should be using a turn detection model. So I'm assuming that you have that right now, you're analyzing a transcript in post. We can remove the speaker labels as well. So it's like a little bit more clear. It's like we just have all the statements that are literally speech to text per line of some kind.\n \n 191\n 00:21:40.560 --> 00:21:42.090\n Vaibhav Gupta: I'm gonna go run this now.\n \n 192\n 00:21:42.310 --> 00:21:43.750\n Vaibhav Gupta: Now you'll notice\n \n 193\n 00:21:44.030 --> 00:21:50.570\n Vaibhav Gupta: the model is actually really, really good at just bidding out the dialogue index, and who the who the speaker is. In each of these scenarios.\n \n 194\n 00:21:51.160 --> 00:21:54.129\n Dexter Horthy: Oh, so it doesn't have to re output the actual text itself.\n \n 195\n 00:21:54.130 --> 00:22:01.560\n Vaibhav Gupta: Exactly order of magnet you can imagine for long transcripts. This is an order of magnitude cheaper\n \n 196\n 00:22:01.870 --> 00:22:07.480\n Vaibhav Gupta: in terms of how much text that's output, and we can reduce this even further and just like aliases to like\n \n 197\n 00:22:07.910 --> 00:22:10.120\n Vaibhav Gupta: alias idx.\n \n 198\n 00:22:11.300 --> 00:22:15.779\n Vaibhav Gupta: And then it'll be a lot shorter. And now it's just now it's just outputting the index, and the speaker.\n \n 199\n 00:22:17.060 --> 00:22:17.420\n Dexter Horthy: I'm.\n \n 200\n 00:22:17.420 --> 00:22:18.020\n Vaibhav Gupta: And.\n \n 201\n 00:22:18.020 --> 00:22:21.630\n Dexter Horthy: A little curious what would happen if you just put it all as one big string.\n \n 202\n 00:22:22.310 --> 00:22:23.859\n Vaibhav Gupta: What do you mean? Oh.\n \n 203\n 00:22:23.860 --> 00:22:28.610\n Dexter Horthy: Like like, if you didn't split them out. I imagine it's probably not gonna work as well, but.\n \n 204\n 00:22:28.930 --> 00:22:42.880\n Vaibhav Gupta: The reason that this works a lot better is twofold one. I'm actually telling it the model what the index is. So the model has to go back and say, Let's look at what the model does turn by turn. It's going to 1st output idx 0,\n \n 205\n 00:22:43.190 --> 00:23:05.820\n Vaibhav Gupta: then all it has to do is in its token. During the attention mechanism the model goes back into its tokenizer, so it literally will go back through all the tokens and just say, Okay, what tokens I want to look at. I want to look at next 0. It's going to go in to say, Okay, I need to understand this part of this part of the segment, it's easier for it to focus. So even though it's a little redundant, it helps the model be a little bit more focused\n \n 206\n 00:23:06.080 --> 00:23:09.710\n Vaibhav Gupta: on its part. Now it's like, Okay, what? Who likely? Said this?\n \n 207\n 00:23:10.540 --> 00:23:26.409\n Vaibhav Gupta: And then it's like, and then it goes out and starts spitting out the next token spits out idx. So at the point of idx, now it says, Oh, what's the next idx I need? Oh, let me go back a couple tokens here is like that was 0. I probably need one. Next, we're reducing the burden on the model.\n \n 208\n 00:23:26.690 --> 00:23:30.190\n Vaibhav Gupta: That's the main. That's the main leverage here.\n \n 209\n 00:23:30.460 --> 00:23:36.670\n Vaibhav Gupta: The model at any point is able to do way less work, and then therefore output more. Does that make sense Dexter.\n \n 210\n 00:23:37.350 --> 00:23:38.699\n Dexter Horthy: Yeah, I got you cool.\n \n 211\n 00:23:39.060 --> 00:23:39.750\n Vaibhav Gupta: Cool.\n \n 212\n 00:23:40.290 --> 00:23:49.089\n Vaibhav Gupta: Now the thing is, we may not actually know exactly who's talking here like this other thing. We might have made a bug and not actually introduced other.\n \n 213\n 00:23:50.160 --> 00:23:54.710\n Vaibhav Gupta: And in this scenario what we'll find is likely the model.\n \n 214\n 00:23:55.790 --> 00:23:57.820\n Vaibhav Gupta: We'll do something just output. It's a nurse.\n \n 215\n 00:23:58.050 --> 00:24:00.389\n Vaibhav Gupta: it kind of hallucinated on its own.\n \n 216\n 00:24:01.010 --> 00:24:03.249\n Vaibhav Gupta: So we can actually just add other\n \n 217\n 00:24:03.780 --> 00:24:11.399\n Vaibhav Gupta: as a fallback. So we, the model doesn't tend to hallucinate. We want to prevent hallucinations when possible, and we do that by giving the model and out. That's the.\n \n 218\n 00:24:11.400 --> 00:24:33.350\n Dexter Horthy: And this is the same with all the all, the classifier examples that that we talk about. Right is like, classify the things you know you are good at classifying in the fastest, cheapest, most efficient way, and then allow the model to have an escape hatch, in which case you'll handle it in a different way, either by sending it to a human to classify or sending it to a bigger, smarter model, or whatever it is.\n \n 219\n 00:24:33.650 --> 00:24:40.320\n Vaibhav Gupta: Exactly. But now let's do another thing. Let's do another thing, clues, but that's some clues here.\n \n 220\n 00:24:40.560 --> 00:24:41.280\n Vaibhav Gupta: So I'm gonna.\n \n 221\n 00:24:41.280 --> 00:24:41.720\n Dexter Horthy: Reasoning.\n \n 222\n 00:24:41.720 --> 00:24:46.840\n Vaibhav Gupta: Things that I'm exactly. So I'm gonna help the model think about what it is. And it's literally just like\n \n 223\n 00:24:47.760 --> 00:24:50.190\n Vaibhav Gupta: it's literally just dumping the text here.\n \n 224\n 00:24:52.141 --> 00:24:59.110\n Vaibhav Gupta: And like this is not very useful. Add description, things that help inference.\n \n 225\n 00:24:59.430 --> 00:25:00.530\n Vaibhav Gupta: To.\n \n 226\n 00:25:01.310 --> 00:25:04.399\n Vaibhav Gupta: Let's just add a little bit more dialogue here, and we'll see what it does.\n \n 227\n 00:25:08.695 --> 00:25:13.750\n Vaibhav Gupta: let's say what might\n \n 228\n 00:25:14.982 --> 00:25:26.379\n Vaibhav Gupta: relevant. So let's so we're noticing that what it's doing is just outputting all the clues, but a lot of the times. It's kind of obvious who the speaker is. So let's just do this only, if not obvious.\n \n 229\n 00:25:28.717 --> 00:25:33.560\n Vaibhav Gupta: List out facts that help us.\n \n 230\n 00:25:35.250 --> 00:25:38.090\n Vaibhav Gupta: Identify, help us, analyze.\n \n 231\n 00:25:38.500 --> 00:25:47.359\n Dexter Horthy: Yeah. John's suggesting deductive reasoning steps, which I think is gets a little towards some of the stuff we've done in the past around like structured reasoning stuff.\n \n 232\n 00:25:47.670 --> 00:25:52.440\n Vaibhav Gupta: There who the speaker may be.\n \n 233\n 00:25:52.980 --> 00:25:55.470\n Vaibhav Gupta: I had a much better test case pulled up earlier.\n \n 234\n 00:25:56.270 --> 00:25:58.649\n Vaibhav Gupta: So and now you're noticing over here.\n \n 235\n 00:25:59.600 --> 00:26:00.020\n Dexter Horthy: Hmm.\n \n 236\n 00:26:00.020 --> 00:26:02.330\n Vaibhav Gupta: Now something a lot more interesting.\n \n 237\n 00:26:03.040 --> 00:26:10.769\n Vaibhav Gupta: It says Speaker 0 other because they don't know yet. Speaker, one uses personal pronouns indicating injury. That means that they're probably a patient\n \n 238\n 00:26:11.430 --> 00:26:16.580\n Vaibhav Gupta: speaking about the patient, so probably other along the way.\n \n 239\n 00:26:18.460 --> 00:26:25.099\n Vaibhav Gupta: So it's actually a lot more useful to actually go do this. And now we can have a lot more comp confidence behind what's happening.\n \n 240\n 00:26:25.960 --> 00:26:30.609\n Dexter Horthy: But it's also it's it's gotten. It's it's gotten worse at picking the ones where it was. The.\n \n 241\n 00:26:30.610 --> 00:26:33.159\n Prashanth Rao: The doctor, the doctor and nurse are worse.\n \n 242\n 00:26:33.650 --> 00:26:35.089\n Vaibhav Gupta: Yes, but\n \n 243\n 00:26:35.690 --> 00:26:45.479\n Vaibhav Gupta: that might be because when you really think about it, doctor and nurse are actually confusing, because how does it actually identify correctly between the doctor and the nurse.\n \n 244\n 00:26:46.720 --> 00:26:48.650\n Vaibhav Gupta: and we can go about this one more time.\n \n 245\n 00:26:48.910 --> 00:26:50.690\n Vaibhav Gupta: And if we actually go, look at this.\n \n 246\n 00:26:50.910 --> 00:26:58.770\n Vaibhav Gupta: If I were to read this transcript. There is no freaking way. I, as a human, would actually be able to know if it's actually a doctor or a patient doctor or not\n \n 247\n 00:27:00.160 --> 00:27:02.420\n Vaibhav Gupta: without knowing how many people are in the room.\n \n 248\n 00:27:03.880 --> 00:27:04.840\n Prashanth Rao: Very true.\n \n 249\n 00:27:05.150 --> 00:27:07.520\n Vaibhav Gupta: I could be talking to my brother.\n \n 250\n 00:27:07.520 --> 00:27:09.780\n Vaibhav Gupta: Exactly, exactly, and that's the.\n \n 251\n 00:27:09.780 --> 00:27:11.610\n Dexter Horthy: Could be my uncle talking shit.\n \n 252\n 00:27:12.360 --> 00:27:22.729\n Vaibhav Gupta: So whenever some, when you said doctor and patient got nurse, you're right. We intuitively felt that way. But remember, the model has no context around this. So let's add some more context.\n \n 253\n 00:27:22.730 --> 00:27:26.790\n Prashanth Rao: Sorry could you go to? So before you clear this out, could you go to the 3rd index? Index? Number 2?\n \n 254\n 00:27:27.900 --> 00:27:30.919\n Prashanth Rao: Yeah, this this time it seems to have gotten it.\n \n 255\n 00:27:31.350 --> 00:27:33.280\n Vaibhav Gupta: Because it's making assumptions.\n \n 256\n 00:27:33.420 --> 00:27:34.319\n Prashanth Rao: Yeah, yeah.\n \n 257\n 00:27:34.320 --> 00:27:36.779\n Vaibhav Gupta: About it right? It's made. But now we.\n \n 258\n 00:27:36.780 --> 00:27:41.590\n Dexter Horthy: Taking more from the prompt itself, like the actual output format, right.\n \n 259\n 00:27:41.590 --> 00:27:48.639\n Vaibhav Gupta: Exactly. It's literally just like, you're probably either doctor or patient, like there's no there's no way around this. But now that we force the model to be like\n \n 260\n 00:27:49.250 --> 00:27:53.159\n Vaibhav Gupta: who, if not only if not obvious, go list out facts.\n \n 261\n 00:27:54.040 --> 00:27:59.940\n Vaibhav Gupta: And in fact, the obvious answer for identifying speakers may be other in all scenarios.\n \n 262\n 00:28:00.970 --> 00:28:06.550\n Vaibhav Gupta: and that's what I would do if I had, I would unlabel everything. But then I would say, Oh.\n \n 263\n 00:28:07.200 --> 00:28:13.100\n Vaibhav Gupta: but now we know for sure that this one is a patient because it has been non obviously stated.\n \n 264\n 00:28:13.840 --> 00:28:16.850\n Vaibhav Gupta: But we can go further. We can make this a little bit better.\n \n 265\n 00:28:18.600 --> 00:28:47.060\n Vaibhav Gupta: There there were 4 people in the room, Dr. Josh, there's 5 h next, the friend unidentified.\n \n 266\n 00:28:48.460 --> 00:28:52.599\n Vaibhav Gupta: So we can go do this cause, maybe, for my Emr. I know exactly who visited.\n \n 267\n 00:28:53.240 --> 00:28:56.819\n Vaibhav Gupta: but I don't know. I don't have any information on the other person at all.\n \n 268\n 00:28:57.660 --> 00:29:04.820\n Vaibhav Gupta: So now let's add this in here and say for context.\n \n 269\n 00:29:12.300 --> 00:29:14.219\n Vaibhav Gupta: And now let's let's run this.\n \n 270\n 00:29:16.850 --> 00:29:20.260\n Vaibhav Gupta: And now what we find is that the model gets a lot better.\n \n 271\n 00:29:21.760 --> 00:29:36.690\n Dexter Horthy: Right? So you could. You could look at like, if you want to do this for a random event, you could go get the people off the Google Calendar event, and just inject that at the top, like, here's the people. And here's their domains. And here's, you know, 2 sentences of deep research about who this person is.\n \n 272\n 00:29:37.100 --> 00:29:53.039\n Vaibhav Gupta: Exactly. And this, this mechanism of how we felt like it got more inaccurate, and might have diverted us from actually exploring this prompt further is actually important to understand why the model did this step back, rethink and remember that the model did this? Because\n \n 273\n 00:29:53.230 --> 00:30:10.189\n Vaibhav Gupta: if I were to be completely objective. Show this to a random person to have tell them identify speakers. They also would likely pick other if they have to be like, if the choice would be wrong or be correct. I, too, would prefer to be not wrong, and just pick other, because other is never wrong.\n \n 274\n 00:30:11.640 --> 00:30:12.390\n Dexter Horthy: Cool.\n \n 275\n 00:30:13.870 --> 00:30:15.880\n Dexter Horthy: Are we gonna trip back? Takes today?\n \n 276\n 00:30:16.120 --> 00:30:20.489\n Vaibhav Gupta: I'll do that in a second. That's Tip number 2, where we use diarization.\n \n 277\n 00:30:20.610 --> 00:30:26.190\n Vaibhav Gupta: And I want to show one last variant of this trick. Which is these clues.\n \n 278\n 00:30:27.120 --> 00:30:39.480\n Vaibhav Gupta: So instead of outputting clues, we can just do this description as a precursor to the comment.\n \n 279\n 00:30:40.090 --> 00:30:45.945\n Vaibhav Gupta: as a precursor sort of comment to this field.\n \n 280\n 00:30:46.800 --> 00:30:47.970\n Vaibhav Gupta: So sometimes we want.\n \n 281\n 00:30:47.970 --> 00:30:48.500\n Dexter Horthy: Shit.\n \n 282\n 00:30:49.940 --> 00:30:55.999\n Vaibhav Gupta: But we don't want it to do reasoning as a data field. I don't want to deal with that. I just wanted to like output something.\n \n 283\n 00:30:56.700 --> 00:30:58.800\n Vaibhav Gupta: and I want to show you what happens here.\n \n 284\n 00:31:00.470 --> 00:31:06.900\n Vaibhav Gupta: If this works exam.\n \n 285\n 00:31:06.900 --> 00:31:18.719\n Dexter Horthy: Okay, so this is getting into like, how do we? How do we? This is a great leeway. This is like, how do we get the model to output busted Json in a way that like actually helps it get better. Answers.\n \n 286\n 00:31:23.560 --> 00:31:26.740\n Dexter Horthy: like comments in Json are technically not valid.\n \n 287\n 00:31:28.270 --> 00:31:31.879\n Vaibhav Gupta: Let's see if I can force it to do this. I have to actually read the prompt and see what it's doing\n \n 288\n 00:31:36.020 --> 00:31:37.210\n Vaibhav Gupta: views.\n \n 289\n 00:31:40.110 --> 00:31:41.240\n Dexter Horthy: As.\n \n 290\n 00:31:42.370 --> 00:32:11.450\n Vaibhav Gupta: If if not, if speaker is ambiguous, list relevant comments the help, narrow help a narrow down toggle\n \n 291\n 00:32:12.700 --> 00:32:14.572\n Vaibhav Gupta: to help narrow down.\n \n 292\n 00:32:15.600 --> 00:32:16.860\n Vaibhav Gupta: No speaker\n \n 293\n 00:32:25.890 --> 00:32:27.320\n Vaibhav Gupta: use 1st\n \n 294\n 00:32:31.240 --> 00:32:31.910\n Vaibhav Gupta: cool.\n \n 295\n 00:32:34.940 --> 00:32:37.180\n Vaibhav Gupta: and we'll go run this and see what the model does.\n \n 296\n 00:32:38.130 --> 00:32:41.199\n Vaibhav Gupta: Okay, I can't get to do it. Let me try and put this out.\n \n 297\n 00:32:44.860 --> 00:32:47.659\n Vaibhav Gupta: This is like the weirdest trick that I've learned, and.\n \n 298\n 00:32:56.490 --> 00:33:00.680\n Dexter Horthy: So, not directly in the generated output format, but just in the prompt.\n \n 299\n 00:33:01.820 --> 00:33:03.130\n Vaibhav Gupta: And the XM.\n \n 300\n 00:33:04.100 --> 00:33:12.450\n Vaibhav Gupta: Use fresh and had, and excellent.\n \n 301\n 00:33:14.120 --> 00:33:14.790\n Dexter Horthy: Okay.\n \n 302\n 00:33:15.000 --> 00:33:18.040\n Dexter Horthy: So you always tell me not to use a few shot prompting.\n \n 303\n 00:33:18.690 --> 00:33:19.600\n Vaibhav Gupta: I do?\n \n 304\n 00:33:21.250 --> 00:33:29.120\n Dexter Horthy: Because this is more about the structure of the response, not about the actual, like learning from examples, basically.\n \n 305\n 00:33:29.120 --> 00:33:30.120\n Vaibhav Gupta: Exactly.\n \n 306\n 00:33:30.610 --> 00:33:35.510\n Vaibhav Gupta: So let's see if I can get the model to output this. And sometimes I can't. Sometimes the model doesn't really listen\n \n 307\n 00:33:36.027 --> 00:33:44.330\n Vaibhav Gupta: and just dump that info as another field. So let's do another last thing prefix equals answer. With\n \n 308\n 00:33:44.630 --> 00:33:48.409\n Vaibhav Gupta: this I noticed Openai has been doing this.\n \n 309\n 00:33:49.250 --> 00:33:58.119\n Vaibhav Gupta: Oh, where like, I think, for whatever reason, whenever you use the word Json, they trigger something special in the prompt that goes to like some other model or something.\n \n 310\n 00:33:58.120 --> 00:34:01.390\n Dexter Horthy: So, or like secretly turns on.\n \n 311\n 00:34:01.390 --> 00:34:03.859\n Vaibhav Gupta: There you go. Yes, exactly.\n \n 312\n 00:34:06.110 --> 00:34:08.535\n Vaibhav Gupta: And now the models actually\n \n 313\n 00:34:09.874 --> 00:34:13.775\n Vaibhav Gupta: writing some more comments. But it's right in the comments after\n \n 314\n 00:34:14.320 --> 00:34:21.739\n Vaibhav Gupta: If list relevant facts helping out on Speaker before the speaker fields see you but be a little.\n \n 315\n 00:34:21.739 --> 00:34:23.969\n Dexter Horthy: Reasoning before the output.\n \n 316\n 00:34:24.159 --> 00:34:24.729\n Vaibhav Gupta: Yeah.\n \n 317\n 00:34:26.265 --> 00:34:33.150\n sahil: Question. So the reason to do this is to save the tokens on item clue. Every single.\n \n 318\n 00:34:33.159 --> 00:34:33.689\n Vaibhav Gupta: Oh, okay.\n \n 319\n 00:34:33.889 --> 00:34:34.690\n sahil: It is.\n \n 320\n 00:34:34.690 --> 00:34:43.710\n Vaibhav Gupta: It's not. It's not always about that. It's just like the model might just. It's just another tool in your toolbox for how you can get the model to output. What you want\n \n 321\n 00:34:44.260 --> 00:34:46.130\n Vaibhav Gupta: clues is one way to do it.\n \n 322\n 00:34:47.620 --> 00:35:02.900\n Dexter Horthy: And you can also do the thing we do. It's like, put the reasoning at the top and then dump the Json, and it sounds like this is just like, okay, if we want really targeted reasoning on each field. And maybe like, this is way more token efficient than having it output a bunch of extra. Json.\n \n 323\n 00:35:03.910 --> 00:35:15.300\n Vaibhav Gupta: Exactly, and you'll notice that you saw me iterate a little bit on this prompt over here, like I did a couple of things to go do this. But this goes into the very next tip that I want to really talk about.\n \n 324\n 00:35:15.410 --> 00:35:17.839\n Vaibhav Gupta: which is one\n \n 325\n 00:35:18.430 --> 00:35:26.989\n Vaibhav Gupta: it's called Rtfp. For those of you that don't know. Rtfm, it means read the fucking manual. Rtfp means read the fucking prompt.\n \n 326\n 00:35:27.397 --> 00:35:41.500\n Vaibhav Gupta: And I say that with a lot of love, because most people don't actually read the prompt. And you saw what I did when this didn't work over here. I just read the prompt I was like, oh, if I go back to the add description mechanism, let me give you a little bit more of a\n \n 327\n 00:35:41.850 --> 00:35:43.699\n Vaibhav Gupta: description of why I didn't like this.\n \n 328\n 00:35:45.120 --> 00:35:51.210\n Vaibhav Gupta: When I go read this, I'm like, oh, this thing over here. Maybe it's getting confused by the double comments.\n \n 329\n 00:35:52.690 --> 00:36:03.010\n Vaibhav Gupta: and you can see how that might be confusing to the model. So since I'm using comments like nested comments and comments, I'm like, okay, let me just try and simplify this problem for the model\n \n 330\n 00:36:03.340 --> 00:36:07.850\n Vaibhav Gupta: and give it that in a place where it can't be confused.\n \n 331\n 00:36:07.990 --> 00:36:11.340\n Vaibhav Gupta: and that was the intuition that I had out here.\n \n 332\n 00:36:12.834 --> 00:36:20.980\n Vaibhav Gupta: So it really just boils on to reading the prompt, because if we can read the prompt, then we can see what the model might be doing. And of course we can never actually know what's actually happening.\n \n 333\n 00:36:21.770 --> 00:36:28.940\n Vaibhav Gupta: but it allows us to actually know what it allows us to iterate a little bit faster, and then we can say, Oh, that isn't working. Let me go fix that.\n \n 334\n 00:36:29.080 --> 00:36:51.790\n Vaibhav Gupta: There's a question about why not use few shot prompting? There's a couple of reasons. Typically the way to have done few shot. Prompting in this example would have been me to actually go and write an example and then write out the answer. But that's not what I wanted. I just wanted the model to understand that it has the ability to go do this. It has the ability to list out facts before it actually spits out the speaker field.\n \n 335\n 00:36:52.160 --> 00:36:56.449\n Vaibhav Gupta: So I just wanted to give it the structure. So it understands the thing it has to mimic.\n \n 336\n 00:36:56.640 --> 00:36:58.450\n Vaibhav Gupta: I don't. It's not the contact.\n \n 337\n 00:36:58.970 --> 00:37:00.490\n Dexter Horthy: Go ahead, Dexter.\n \n 338\n 00:37:00.690 --> 00:37:23.570\n Dexter Horthy: And all this is again, is like, Okay, cool, like, yeah. Probably just outputting. Json is good enough. Outputting. Reasoning. 1st is a little bit better. Having reasoning in your Json. Fields is probably a little bit better. But if you're running this kind of thing a hundred 1,000 times a day, then a tiny half a percent improvement, either in efficiency or in speed or in token efficiency or in accuracy.\n \n 339\n 00:37:23.570 --> 00:37:34.359\n Dexter Horthy: is massively valuable. And this is what we talk about every week on this show like, how do you? How do you unlock those like near the top of the accuracy range? How do you push things even further.\n \n 340\n 00:37:34.720 --> 00:37:36.750\n Vaibhav Gupta: Yeah, how do you get another half a percent?\n \n 341\n 00:37:37.150 --> 00:37:41.709\n Vaibhav Gupta: And this isn't. Again, remember, this isn't say that this technique will work always.\n \n 342\n 00:37:42.270 --> 00:37:51.590\n Vaibhav Gupta: But it is another technique that you have available to yourself, just like we use this other technique to not spit out the entire dialog, but rather only spit out the index.\n \n 343\n 00:37:52.500 --> 00:37:59.219\n Vaibhav Gupta: And we use this other technique to say, Oh, dialogue index is actually a lot more tokens. Let's use purely the word index\n \n 344\n 00:37:59.420 --> 00:38:03.289\n Vaibhav Gupta: instead. So it spits out. The output. Tokens are way less.\n \n 345\n 00:38:03.290 --> 00:38:07.980\n Vaibhav Gupta: Hi, Chris, it's small things that can make a difference. And if I actually were to look at this.\n \n 346\n 00:38:08.160 --> 00:38:12.799\n Vaibhav Gupta: my punch actually says index itself, where to go.\n \n 347\n 00:38:12.800 --> 00:38:13.430\n Dexter Horthy: And.\n \n 348\n 00:38:13.430 --> 00:38:27.209\n Vaibhav Gupta: Index is probably wrong. I should actually probably use like index, because this is just a more popular token that the model will have understandings of, or rather than idx, even though idx is a single token. It's just more commonly understood.\n \n 349\n 00:38:27.970 --> 00:38:29.320\n Dexter Horthy: Existing processes.\n \n 350\n 00:38:30.306 --> 00:38:32.280\n Vaibhav Gupta: Cool, so.\n \n 351\n 00:38:32.280 --> 00:38:57.380\n sahil: Question, quick question. So we do this actually hundreds and thousands of times a day where we put out reasoning. And we use the reasoning as for another model, so is there a way to achieve or make it a bit more efficient? So we literally spit out clues, and these are at least a long sentence.\n \n 352\n 00:38:58.820 --> 00:39:02.800\n sahil: So any any tips or tricks do.\n \n 353\n 00:39:03.108 --> 00:39:10.200\n Vaibhav Gupta: If you really wanted, if you really wanted like if you really wanted that, I would actually put your reasoning afterwards\n \n 354\n 00:39:10.610 --> 00:39:12.060\n Vaibhav Gupta: like assessment.\n \n 355\n 00:39:14.540 --> 00:39:26.120\n Vaibhav Gupta: So if you want to do an eval thing right over here, description, final assessment of the speaker.\n \n 356\n 00:39:26.440 --> 00:39:35.159\n Vaibhav Gupta: Given any clues prior clues in comments, I received this\n \n 357\n 00:39:38.210 --> 00:39:44.669\n Vaibhav Gupta: and just like, let the model spit it out. And now you can use assessment as a thing. But now you'll see that assessment is actually kind of big.\n \n 358\n 00:39:44.850 --> 00:39:47.350\n Vaibhav Gupta: So what I'll do is like use phrases\n \n 359\n 00:39:52.283 --> 00:39:58.100\n Vaibhav Gupta: not complete sentences. And then I would also add into here\n \n 360\n 00:40:01.260 --> 00:40:02.150\n Vaibhav Gupta: assessment.\n \n 361\n 00:40:03.720 --> 00:40:11.949\n Vaibhav Gupta: So now I'll notice over here what it's doing, and it will just spit something out, and I would probably have to tweak this model. So sometimes Gt. 4 is not very good. So let me try. Anthropic.\n \n 362\n 00:40:13.510 --> 00:40:15.320\n Vaibhav Gupta: Is that the right model? We'll find out.\n \n 363\n 00:40:15.910 --> 00:40:17.390\n Vaibhav Gupta: Oh, that is not the right model.\n \n 364\n 00:40:18.290 --> 00:40:20.210\n Dexter Horthy: Dude, I think it's 1020.\n \n 365\n 00:40:23.440 --> 00:40:25.040\n Dexter Horthy: 2024, 1020.\n \n 366\n 00:40:25.670 --> 00:40:27.050\n Vaibhav Gupta: Custom, sonic.\n \n 367\n 00:40:27.640 --> 00:40:28.340\n Dexter Horthy: There you go!\n \n 368\n 00:40:29.880 --> 00:40:34.320\n Vaibhav Gupta: Oh, I don't have an Api key! One second. I will not be sharing my Api key this time around.\n \n 369\n 00:40:35.050 --> 00:40:38.260\n Dexter Horthy: Oh, that's why I come here every week.\n \n 370\n 00:40:38.390 --> 00:40:41.000\n Dexter Horthy: It's because you always you always leak at least one key.\n \n 371\n 00:40:41.400 --> 00:40:43.210\n Vaibhav Gupta: Also forget to deactivate it.\n \n 372\n 00:40:47.090 --> 00:40:50.010\n Vaibhav Gupta: Okay, let me.\n \n 373\n 00:40:53.290 --> 00:40:57.440\n Dexter Horthy: Yeah, and just answering it while he's doing that, answering the question on the thread.\n \n 374\n 00:40:58.544 --> 00:41:04.736\n Dexter Horthy: why not use few shot prompting. We talked about this a little bit. But it's basically\n \n 375\n 00:41:05.340 --> 00:41:11.930\n Dexter Horthy: the content of the examples tends to greatly steer the model's response.\n \n 376\n 00:41:12.290 --> 00:41:21.450\n Dexter Horthy: And like you can get, you can get the right structural results without actually putting content in your examples.\n \n 377\n 00:41:22.200 --> 00:41:23.030\n Vaibhav Gupta: Yes.\n \n 378\n 00:41:23.719 --> 00:41:37.190\n Vaibhav Gupta: so there we go. So now you can see over here when I switch this Claude, I actually get really nice things where it's assessment comes with this. And now you could plug this into your evals. We got a way less tokens out here. It's way. It's way shorter\n \n 379\n 00:41:38.360 --> 00:41:56.589\n Vaibhav Gupta: because we're not using complete sentences. So if you really care about evals and want to like you want to store the data anyway, go do that. But honestly, if you're up to me, I wouldn't do any of this Eval stuff online, I would have a separate process that pulls all my data down and runs a separate Eval, including the assessment for each of these segments off the raw data itself\n \n 380\n 00:41:57.240 --> 00:42:08.659\n Vaibhav Gupta: and just run a completely separate process. It's going to be way cheaper way faster, because don't add more latency to a pipeline that has this. Each of these things that you're generating here is latency. So a very latency, sensitive pipeline generally for speech to text.\n \n 381\n 00:42:10.240 --> 00:42:10.970\n Dexter Horthy: Cool.\n \n 382\n 00:42:12.075 --> 00:42:23.119\n Vaibhav Gupta: Cool. Let's talk about so at this point we've covered labels. Don't use uids. Don't use you urls use like indexes whenever possible and remap them programmatically to the right thing.\n \n 383\n 00:42:23.370 --> 00:42:33.389\n Vaibhav Gupta: We've talked about. Diarization don't emit the full transcript. Have the again, have the index, have the model represent something that is way better than the full transcript. In this case an index of the transcript\n \n 384\n 00:42:33.810 --> 00:42:38.110\n Vaibhav Gupta: we've talked about using inline comments to guide reasoning of sorts.\n \n 385\n 00:42:38.350 --> 00:42:53.019\n Vaibhav Gupta: We've talked about Re. Rtfd. Reading the prompt read it always, especially when you get stuck instead of trying to keep prompting more. Just keep reading it. We've talked about few shot prompting with structure, not with actual content, and how we can leverage that along the way.\n \n 386\n 00:42:53.770 --> 00:42:59.269\n Vaibhav Gupta: And I think the next thing I want to talk about is something that we've mentioned a few times. But it's all about Cogen.\n \n 387\n 00:42:59.990 --> 00:43:06.370\n Vaibhav Gupta: So I'm going to go ahead and pull up a random new file.\n \n 388\n 00:43:06.720 --> 00:43:19.140\n Anubhav: Hey, web Anupav! Here, before you move forward, I in my mind I'm still confused about using this technique where you somehow use Ginger to get an index on that array.\n \n 389\n 00:43:20.230 --> 00:43:22.640\n Vaibhav Gupta: I, yeah, good.\n \n 390\n 00:43:22.850 --> 00:43:29.829\n Anubhav: Versus using symbol tuning thing. So when to use what.\n \n 391\n 00:43:30.255 --> 00:43:30.680\n Vaibhav Gupta: Okay.\n \n 392\n 00:43:30.680 --> 00:43:35.760\n Vaibhav Gupta: okay, so just for context, let me just pull up a symbol to example. So then I, we can just talk about it.\n \n 393\n 00:43:39.840 --> 00:43:40.959\n Dexter Horthy: And it was the second or 3.rd\n \n 394\n 00:43:40.960 --> 00:43:42.890\n Vaibhav Gupta: Services. That's like the one\n \n 395\n 00:43:43.561 --> 00:43:51.359\n Vaibhav Gupta: I have symbol tuning right here. So the idea of symbol tuning is I want to do a classification example. I guess I'll do this\n \n 396\n 00:43:52.430 --> 00:43:55.900\n Vaibhav Gupta: symbol doing a\n \n 397\n 00:44:08.197 --> 00:44:17.240\n Vaibhav Gupta: I have a classification prompt instead of actually classifying the prompt. I want them all to spit out one of these categories, and I have a couple of different ways. I can go do this. Oh, that's interesting.\n \n 398\n 00:44:18.680 --> 00:44:22.739\n Vaibhav Gupta: I have a couple of different ways that I can go do this. But one of the ways is like.\n \n 399\n 00:44:23.400 --> 00:44:25.660\n Vaibhav Gupta: instead of the model actually spitting out\n \n 400\n 00:44:26.495 --> 00:44:35.540\n Vaibhav Gupta: all of my classes, I can. And instead of actually writing like the word refund in the prompt, I can write just the symbol, k. 1.\n \n 401\n 00:44:35.980 --> 00:44:37.750\n Vaibhav Gupta: And when the model runs this\n \n 402\n 00:44:37.950 --> 00:44:52.139\n Vaibhav Gupta: it will spit out K. 4, which then gets remapped to account issue for me automatically. The benefit of this approach is the model. Again, it's same. It's the exact same thing as the Youtube URL thing, where the model, when it sees the word account issue.\n \n 403\n 00:44:52.270 --> 00:45:02.139\n Vaibhav Gupta: it associates these tokens with something semantically meaningful. And what I want to do is my meaning of an account issue is actually encoded in my description way. Better than that.\n \n 404\n 00:45:02.140 --> 00:45:03.360\n Dexter Horthy: You want to say\n \n 405\n 00:45:03.610 --> 00:45:14.489\n Dexter Horthy: 0 attention on the label name, because that's for the coders and the program that's consuming this all attention on the description, so that I can control exactly what the Lm. Is going to output.\n \n 406\n 00:45:15.060 --> 00:45:21.420\n Vaibhav Gupta: Exactly exactly. It's about reducing the number of variability in the problem, Dexter said it beautifully.\n \n 407\n 00:45:21.930 --> 00:45:28.019\n Vaibhav Gupta: and symbol tuning is a technique. Lets me do this, the thing that we're talking about with diarization, where we output\n \n 408\n 00:45:28.633 --> 00:45:40.319\n Vaibhav Gupta: where we actually output like the actual index here, that's basically the same thing instead of the model outputting the actual text of the line, it's outputting the index of the line in the conversation.\n \n 409\n 00:45:40.660 --> 00:45:49.800\n Vaibhav Gupta: and instead of letting the model infer the index. Because I could do that. I don't actually have to write this. I could just let the model infer the index by writing something like this instead.\n \n 410\n 00:45:51.090 --> 00:45:52.950\n Dexter Horthy: Just in the model break. Yeah.\n \n 411\n 00:45:52.950 --> 00:45:58.019\n Vaibhav Gupta: Model could count. But why make the life harder for the model like this?\n \n 412\n 00:45:58.020 --> 00:46:04.910\n Dexter Horthy: Yeah. Now you're asking the model to count shit. Are you kidding me? That's terrifying. It's like, it's like, you know, when you do these coding agents, and you have, like\n \n 413\n 00:46:05.070 --> 00:46:11.650\n Dexter Horthy: no line numbers in the file versus every time you give it to the model, give it line numbers, and suddenly it can do these edits way. Better, right?\n \n 414\n 00:46:12.060 --> 00:46:20.929\n Vaibhav Gupta: Exactly, and this goes back to Rtfp. If I read this prompt even as a human. I know exactly what index this is without having to spend any time about it.\n \n 415\n 00:46:21.690 --> 00:46:26.039\n Vaibhav Gupta: But if I don't have these lines in there that becomes a lot harder for me to go, do.\n \n 416\n 00:46:26.520 --> 00:46:44.909\n Vaibhav Gupta: And I think it's small things like this that actually, dramatically change the quality of your outputs in a way that I think can make a huge difference. So I hope. I related the questions across the board, for the one of how simple tuning relates to diarization and the examples.\n \n 417\n 00:46:45.750 --> 00:47:15.680\n Dexter Horthy: And I. We won't go into this today, I think. But, like again, take all the advice from the Evals chapter and like, Don't go just applying all this stuff, willy, nilly like, get a real set. Understand what how your performance is today. Try changing these small things, you know whether it's like, Oh, I found a bug from production. Let me drop it in as a test case, and just change the prompt until I fix this one without breaking all the other ones, or even having a bigger Eval set, which is like, Hey, our accuracy is 84%. And if I make this change and run the exact same data through the pipeline. Now, it's 88%.\n \n 418\n 00:47:16.420 --> 00:47:18.610\n Vaibhav Gupta: Exactly exactly.\n \n 419\n 00:47:19.940 --> 00:47:20.570\n Vaibhav Gupta: Let's.\n \n 420\n 00:47:20.570 --> 00:47:21.000\n Dexter Horthy: Cool.\n \n 421\n 00:47:21.000 --> 00:47:25.330\n Vaibhav Gupta: Let's talk with the last part. Cogen. This is something we showed a couple of times, and this is kind of\n \n 422\n 00:47:25.790 --> 00:47:27.650\n Vaibhav Gupta: ex-related.\n \n 423\n 00:47:28.250 --> 00:47:45.929\n Dexter Horthy: Yeah, this directly leads from the other one, because it's again, it's like, how do we get the model to create invalid Json for good like, how? How can? By getting the model to create broken Json, you can actually get way. Better performance. And we'll talk about like, why, that works by looking like under the hood at like samplers and stuff right.\n \n 424\n 00:47:46.380 --> 00:47:48.290\n Vaibhav Gupta: Yeah, let's do that. That's actually a good idea.\n \n 425\n 00:47:48.630 --> 00:47:49.650\n Vaibhav Gupta: So in this case.\n \n 426\n 00:47:49.650 --> 00:47:50.480\n Dexter Horthy: I want to.\n \n 427\n 00:47:50.480 --> 00:47:55.809\n Vaibhav Gupta: Generate some code. And I'll say, a binary search tree\n \n 428\n 00:47:56.020 --> 00:48:04.820\n Vaibhav Gupta: with actually, no, let's do this. A sorting algorithm with merge sort.\n \n 429\n 00:48:05.260 --> 00:48:10.019\n Vaibhav Gupta: Alright cool. That's record that's redundant. So let's do this. Firstly.\n \n 430\n 00:48:11.540 --> 00:48:16.179\n Vaibhav Gupta: and it's gonna output this. And again, if I have a chat app, this is excellent.\n \n 431\n 00:48:17.680 --> 00:48:29.859\n Vaibhav Gupta: This is really really excellent. I could show this to the user. They'll be pretty happy, and we'll see the quality of the code right here. It looks pretty good. It has some comments and stuff in it. It looks generally useful.\n \n 432\n 00:48:30.490 --> 00:48:31.539\n Vaibhav Gupta: but the minute.\n \n 433\n 00:48:31.540 --> 00:48:44.149\n Dexter Horthy: This is the way models want to write code, by the way, like this is, if you if you just want to get the very best code performance. Let it write it between Markdown back ticks, because that is what is the majority present in the training set.\n \n 434\n 00:48:44.490 --> 00:48:45.060\n Vaibhav Gupta: Yeah.\n \n 435\n 00:48:45.170 --> 00:48:54.929\n Vaibhav Gupta: Now, I'm gonna change this to actually return a data model. Because, hey, I want the code so I can go find it. I don't do some parsing. I want to render it just the code part without all this prefix. Or maybe I want to go run it and go do something.\n \n 436\n 00:48:54.930 --> 00:49:00.789\n Dexter Horthy: You don't want to have to write code to strip out that like python back ticks thing because you're just going to turn around and run it. Maybe.\n \n 437\n 00:49:01.310 --> 00:49:05.699\n Vaibhav Gupta: And now we got this, and I don't actually know the quality of this code.\n \n 438\n 00:49:06.130 --> 00:49:22.800\n Vaibhav Gupta: but we'll see. All I do know is it did output a lot of things, and I want everyone to know something very, very important here. This is actually what the model output. This is raw. I just copied. Directly the string the model came out with. If I go back to the Tokenizer I'll show you. I want to show everyone what this means.\n \n 439\n 00:49:24.500 --> 00:49:26.120\n Vaibhav Gupta: We can see what it did.\n \n 440\n 00:49:26.600 --> 00:49:29.239\n Dexter Horthy: Yo slash and n are 2 different tokens.\n \n 441\n 00:49:29.560 --> 00:49:31.180\n Vaibhav Gupta: Yeah, exactly. So it's actually.\n \n 442\n 00:49:31.180 --> 00:49:32.250\n Dexter Horthy: That's crazy.\n \n 443\n 00:49:32.250 --> 00:49:41.360\n Vaibhav Gupta: It's outputting a bunch of space characters. It's it's not actually outputting code. It's outputting something slightly different. It's something that looks like code.\n \n 444\n 00:49:41.700 --> 00:49:47.359\n Dexter Horthy: Will you? Sorry? Can I screenshot that? And then can you drop the other output into the tokenizer as well.\n \n 445\n 00:49:48.360 --> 00:49:49.030\n Vaibhav Gupta: Yeah. Why not?\n \n 446\n 00:49:49.030 --> 00:49:51.060\n Dexter Horthy: Back and let me get a screenshot real quick.\n \n 447\n 00:49:52.910 --> 00:49:54.870\n Vaibhav Gupta: Yeah, I'll put side by side. How about that?\n \n 448\n 00:49:55.180 --> 00:49:59.260\n Dexter Horthy: Okay, yeah, because I think this is really important.\n \n 449\n 00:50:01.780 --> 00:50:02.400\n Vaibhav Gupta: Okay.\n \n 450\n 00:50:09.070 --> 00:50:14.369\n Dexter Horthy: So if you get rid of the back ticks and the actual like, preamble and stuff, how do the token.\n \n 451\n 00:50:14.370 --> 00:50:23.309\n Vaibhav Gupta: No, I'll I'll leave that in there, actually. Because I think it's important. And this one has like a Java example as well. So why not get rid of the Java example.\n \n 452\n 00:50:23.840 --> 00:50:24.500\n Dexter Horthy: Yeah.\n \n 453\n 00:50:24.680 --> 00:50:26.857\n Vaibhav Gupta: Just to like, keep it in.\n \n 454\n 00:50:29.100 --> 00:50:34.660\n Vaibhav Gupta: There's something in here cool.\n \n 455\n 00:50:34.770 --> 00:50:38.229\n Vaibhav Gupta: and this seems to have a print example as well. So we leave that in there.\n \n 456\n 00:50:38.630 --> 00:50:54.549\n Vaibhav Gupta: What we'll notice here is not. It's not really about the token counts or anything else. What's really important here is like the quality of the code that's being generated. 1st thing that we notice upfront is recursively sort both halves. So this comes out. And then, if we go look at this all these backslash ends\n \n 457\n 00:50:54.940 --> 00:51:01.370\n Vaibhav Gupta: are actually having to be forcefully generated by the model, to be correctly syntactical. Json out of here.\n \n 458\n 00:51:02.060 --> 00:51:05.690\n Dexter Horthy: Because you can't have new lines in Json. You have to have escaped new lines.\n \n 459\n 00:51:05.940 --> 00:51:11.489\n Vaibhav Gupta: Exactly, instead of letting the model just do escape new lines. So what if we just told the model to go do that instead?\n \n 460\n 00:51:11.740 --> 00:51:26.470\n Vaibhav Gupta: What we'll find is code description. Use, use triple use back, take use triple backticks, the format code, code.\n \n 461\n 00:51:26.930 --> 00:51:28.010\n Vaibhav Gupta: python.\n \n 462\n 00:51:30.680 --> 00:51:34.639\n Vaibhav Gupta: and let's go read the Prompt. Let's see what the prompt looks like. This is what the prompt looks like.\n \n 463\n 00:51:35.070 --> 00:51:37.020\n Vaibhav Gupta: Use triple backfix to read the prompt\n \n 464\n 00:51:39.600 --> 00:51:42.870\n Vaibhav Gupta: And now, when I go run this, what I get\n \n 465\n 00:51:42.980 --> 00:51:46.589\n Vaibhav Gupta: is the model output code exactly how I was outputting before.\n \n 466\n 00:51:48.320 --> 00:51:51.280\n Vaibhav Gupta: but in a way that still allows me to do structured promptly.\n \n 467\n 00:51:51.900 --> 00:52:12.870\n Dexter Horthy: So this is not valid, Json, and like the subtle thing here is like. And this is kind of like, I think we're having a conversation yesterday about like one of the cool things you can do with Bamel, and why, having a parser that is separate from the that is outside of the model itself is really powerful is because you can let the model use regular new lines and its output, and then turn them back into J, like regular, like Json, that works.\n \n 468\n 00:52:14.330 --> 00:52:19.900\n Vaibhav Gupta: Yes, so now let's go. Do this. Now, I want to make this as a lesson plan\n \n 469\n 00:52:20.140 --> 00:52:24.469\n Vaibhav Gupta: for the following, input as a lesson with diffs.\n \n 470\n 00:52:26.250 --> 00:52:30.260\n Vaibhav Gupta: So now, what I'm going to do is I'm going to output an array of code snippets.\n \n 471\n 00:52:30.700 --> 00:52:31.970\n Vaibhav Gupta: Not one\n \n 472\n 00:52:32.970 --> 00:52:39.719\n Vaibhav Gupta: but multiple arrays. And then I'm gonna say, make a plan. To for to go do this example.\n \n 473\n 00:52:41.970 --> 00:52:46.170\n Vaibhav Gupta: Section one. Blah blah blah section 2, blah blah blah blah\n \n 474\n 00:52:49.180 --> 00:52:56.280\n Vaibhav Gupta: cool. And again, what do you think? Few shop the example of using comments as guiding principles? We're gonna do the same thing here.\n \n 475\n 00:52:57.200 --> 00:52:59.609\n Vaibhav Gupta: and then we'll add a little title here, string\n \n 476\n 00:53:02.270 --> 00:53:10.530\n Dexter Horthy: This is funny. This is what I actually did for a workshop a couple weeks ago, was we had said, Hey, here's the final product, output it as sections in a lesson plan.\n \n 477\n 00:53:12.130 --> 00:53:13.819\n Vaibhav Gupta: So now we're gonna do the same thing.\n \n 478\n 00:53:15.670 --> 00:53:18.080\n Vaibhav Gupta: And now what the model is, I'm fixing this bug.\n \n 479\n 00:53:18.390 --> 00:53:23.029\n Dexter Horthy: I mean, this is cool. But why, why would you want to do it this way? Why would you want to do this?\n \n 480\n 00:53:23.030 --> 00:53:23.880\n Dexter Horthy: It's like us.\n \n 481\n 00:53:24.140 --> 00:53:34.370\n Vaibhav Gupta: I'll show you the output, because I think the output will make it more clear. So the 1st thing is, I wanted to build a lesson plan so I did reasoning for like what lesson plan I wanted to go do. So it said, what we're gonna do this.\n \n 482\n 00:53:34.540 --> 00:53:36.580\n Vaibhav Gupta: then it's going to actually output the code\n \n 483\n 00:53:36.920 --> 00:53:47.039\n Vaibhav Gupta: and create a merge function that combines 2 sort of arrays. Great create a basic merge sort function with recursion. So it's actually incrementing it. Now you can imagine that I walk someone through the code\n \n 484\n 00:53:47.360 --> 00:53:48.620\n Vaibhav Gupta: one by one.\n \n 485\n 00:53:49.850 --> 00:54:03.160\n Vaibhav Gupta: right. And now it's intending with array, splitting recursive calls. So now it's incrementally going to do this. Now I can build a ui on top of this. That literally has step one step, 2, step 3, and teach someone merge sort with this benefit along the way.\n \n 486\n 00:54:04.580 --> 00:54:10.440\n Vaibhav Gupta: right and along the whole time. If I get rid of this section I will. I will literally just comment this part out.\n \n 487\n 00:54:11.750 --> 00:54:15.319\n Vaibhav Gupta: I'll show you how much harder it becomes for the model to actually generate this\n \n 488\n 00:54:19.140 --> 00:54:24.490\n Vaibhav Gupta: like this is now like becoming significantly harder\n \n 489\n 00:54:24.720 --> 00:54:29.500\n Vaibhav Gupta: for the model to actually keep track of its own code, because even as a developer\n \n 490\n 00:54:29.750 --> 00:54:43.019\n Vaibhav Gupta: this would be very, very hard for me to even unread and understand this and most of the training data and the models Codegen doesn't actually have backslash ends as this. It has it as the actual backslash end.\n \n 491\n 00:54:43.250 --> 00:54:52.550\n Vaibhav Gupta: So code quality that you're getting is going to be way worse. So when we go to like a harder problem, let's go into a harder problem, because merge sort is something that we all know, like even the basic models can go do.\n \n 492\n 00:54:54.820 --> 00:54:58.160\n Vaibhav Gupta: Create a what is it? What's a harder problem next, sir?\n \n 493\n 00:54:59.129 --> 00:55:04.069\n Dexter Horthy: Kubernetes operator to spin up Rds. Instances in Golang.\n \n 494\n 00:55:08.830 --> 00:55:10.760\n Vaibhav Gupta: To spin up our.\n \n 495\n 00:55:10.760 --> 00:55:14.049\n Dexter Horthy: Spin up yeah instances and go lang.\n \n 496\n 00:55:15.080 --> 00:55:16.789\n Vaibhav Gupta: I have no idea.\n \n 497\n 00:55:18.680 --> 00:55:22.449\n Vaibhav Gupta: I have no idea what half those words mean, because sadly, I work in algorithms land.\n \n 498\n 00:55:23.300 --> 00:55:25.390\n Vaibhav Gupta: and we're seeing what the model is. So I want you.\n \n 499\n 00:55:25.390 --> 00:55:26.620\n Dexter Horthy: Oh, it made a diff.\n \n 500\n 00:55:26.960 --> 00:55:28.020\n Dexter Horthy: Yes.\n \n 501\n 00:55:28.020 --> 00:55:29.360\n Vaibhav Gupta: Maldo's made a death.\n \n 502\n 00:55:29.510 --> 00:55:41.060\n Vaibhav Gupta: I also want us to notice a couple other things. The model actually, intuitively just put out back tick new lines. Anyway, it actually was like, you know, what I am not going to put out backslash ends. I'm just going to spit out this.\n \n 503\n 00:55:41.230 --> 00:55:43.789\n Vaibhav Gupta: So model intuitively did this for us\n \n 504\n 00:55:44.930 --> 00:55:50.049\n Vaibhav Gupta: without us even having to prompt at that. And that just goes to show that the model's intuitive behavior\n \n 505\n 00:55:50.470 --> 00:55:57.399\n Vaibhav Gupta: is not to spit out, escaped Json, and the reason it probably did this\n \n 506\n 00:55:57.670 --> 00:56:08.230\n Vaibhav Gupta: is because go is just a lot more technical than python or typescript and other things. So the minute it got to like a hard mode problem. It did the most basic things for itself.\n \n 507\n 00:56:09.290 --> 00:56:16.300\n Dexter Horthy: Yeah, you wanna pop back to the whiteboard for really quick and just highlight. I I wanna highlight this sampling part of this\n \n 508\n 00:56:17.900 --> 00:56:19.108\n Vaibhav Gupta: So you have it too.\n \n 509\n 00:56:19.350 --> 00:56:20.200\n Dexter Horthy: Yeah. Yeah.\n \n 510\n 00:56:24.300 --> 00:56:24.790\n Vaibhav Gupta: There you go!\n \n 511\n 00:56:24.790 --> 00:56:38.520\n Dexter Horthy: So, okay, so you got that up scroll down a little bit. So basically like, if if you know how samplers work, essentially, you have at any given point. You have, you know, the models writing code, and it's writing, like, you know, code\n \n 512\n 00:56:38.690 --> 00:56:44.490\n Dexter Horthy: import OS, and then at any given point, it's it's we're at. Let's say we're right here.\n \n 513\n 00:56:44.760 --> 00:56:58.430\n Dexter Horthy: and we're generating like. Then we're asking what's the next token? At this moment there is, you know, and a distribution of what the next token is going to be right. And in this case it's almost always going to be like\n \n 514\n 00:56:58.530 --> 00:57:08.779\n Dexter Horthy: new line kind of classic new line. And then there's going to be a long tail of other characters. That might be next right? You might have, you know, semicolon here.\n \n 515\n 00:57:10.260 --> 00:57:29.840\n Dexter Horthy: because maybe some code has like import OS semicolon. And then another import. Maybe if it's red code serialized in Json, maybe there is a backslash here which is going to lead it to correctly type the slash N, and maybe there's some other characters here defined by your temperature, right of like different probabilities of that. That's the next token?\n \n 516\n 00:57:30.270 --> 00:57:31.310\n Dexter Horthy: Does it make sense.\n \n 517\n 00:57:31.830 --> 00:57:32.460\n Vaibhav Gupta: Yup!\n \n 518\n 00:57:33.040 --> 00:57:47.999\n Dexter Horthy: So when you put on strict mode or strict Json mode, and even in some of the more like old school function calling modes, they're starting to enforce this. Basically that is going to when the model gets to its like time to do the correct output.\n \n 519\n 00:57:48.030 --> 00:58:10.569\n Dexter Horthy: It's just going to X out anything that would break the Json schema, which means that a new line is not a valid character, because a new line is not valid, Json, and this is why, when people say, like, you know, using strict mode reduces the accuracy of your outputs, it's because now you're removing the big one, and you have a very, very like\n \n 520\n 00:58:10.730 --> 00:58:30.700\n Dexter Horthy: tight distribution of the other things. Now these probabilities get balanced out, and you have a bunch of things that are like probably next, but like not clear. And so you're likely to get weird janky code with like semicolons in it, instead of backslashes, or even like invalid syntax, because you're not letting the model write code in the way that it's been trained to write code.\n \n 521\n 00:58:31.550 --> 00:58:38.520\n Vaibhav Gupta: Yeah. And this applies not just for Cogen, but applies to any domain where anytime you're having the model not pick its best token.\n \n 522\n 00:58:38.920 --> 00:58:44.290\n Vaibhav Gupta: You're basically telling the model like you know better than model, which may be true in some scenarios. I want to articulate that.\n \n 523\n 00:58:44.910 --> 00:58:50.219\n Vaibhav Gupta: But most of the time in machine learning. What we've learned is, let the model do what it does best\n \n 524\n 00:58:50.350 --> 00:59:05.340\n Vaibhav Gupta: and just let it output the best token. And in computer vision we had this problem all the time, where we always let the model, like we trying to be very clever about the model where we do. Oh, let's do this pre-processing. Let's do this post-processing. It turned out the best answer, as all the Vlms have showed.\n \n 525\n 00:59:05.470 --> 00:59:06.670\n Vaibhav Gupta: is literally just\n \n 526\n 00:59:07.100 --> 00:59:15.579\n Vaibhav Gupta: give it all to the model. Let it decide, and I think the same thing is true with token, generation, or everything else too like. Don't try and be clever with token generation. Let's let the model pick the best token.\n \n 527\n 00:59:17.052 --> 00:59:34.890\n Vaibhav Gupta: I think that's all we have time for today in terms of actual topics and prompting techniques. I hope that this was incredibly useful for everyone else. What we'll do for the next 1520 min is I'll go to the discord, and I'll see what prompts that we have submitted, if we have any at all.\n \n 528\n 00:59:35.290 --> 00:59:35.810\n Vaibhav Gupta: and.\n \n 529\n 00:59:35.810 --> 00:59:36.930\n Dexter Horthy: There's a couple in here.\n \n 530\n 00:59:37.350 --> 00:59:40.069\n Vaibhav Gupta: Oh, there are! Oh, that's actually more than I expected!\n \n 531\n 00:59:40.993 --> 00:59:41.720\n Dexter Horthy: There's 2.\n \n 532\n 00:59:41.890 --> 00:59:43.740\n Vaibhav Gupta: Exact. That's more than I expected.\n \n 533\n 00:59:45.520 --> 00:59:47.419\n Vaibhav Gupta: Here is, I'll go. Do this.\n \n 534\n 00:59:47.600 --> 00:59:49.440\n Vaibhav Gupta: Let's just bring this one up.\n \n 535\n 00:59:51.290 --> 01:00:08.250\n Vaibhav Gupta: I use this prompt to evaluate Llms on their ability to make sense of Lm generated events. But before we go into this, does anyone have questions while I go read this prompt that people want to go, ask for, feel free to come off mute, and just ask if you, after you raise your hand and come on in.\n \n 536\n 01:00:11.660 --> 01:00:20.379\n Jonathan Ng: So I do have a question about that code. Gen stuff. Just because, like, when we're talking, yeah, I do agree that like letting the\n \n 537\n 01:00:20.510 --> 01:00:36.900\n Jonathan Ng: Codegen do its thing is much better and produces a lot better results. But, on the other hand, like, when you're working in an established code base. Usually it has its own like style and things like that.\n \n 538\n 01:00:37.441 --> 01:00:39.729\n Jonathan Ng: How do you resolve that problem?\n \n 539\n 01:00:41.710 --> 01:00:57.629\n Vaibhav Gupta: Yeah, my desk might have his own opinions. My answer for all that is always the same thing, which is just add more software on top of it. If you want stuff to be formatted in a good way, literally just run a linter on the generated code, it will be formatted exactly how you want it to be formatted.\n \n 540\n 01:00:57.920 --> 01:01:10.730\n Vaibhav Gupta: If you don't have a linter with an opinionated formatting, it's probably not mimicking that if you, if you feel like you don't have the linther rules. Go write a quick lm, prompt to look at your existing code, generate Linter rules off of that, and then go run the formatter\n \n 541\n 01:01:11.515 --> 01:01:11.990\n Vaibhav Gupta: but.\n \n 542\n 01:01:11.990 --> 01:01:35.149\n Dexter Horthy: Oh, because what I've seen in coding agents is a lot of like, okay, cool. Read a couple like, if you're using clock code or something. It reads a couple files, and then what it's read in the code base already kind of propagates down to the next code it generates, but it almost sounds like what would be much more efficient would be like. Take a couple of the files and have the model generate either like Hardcore Linter, because not all style can be enforced by a linter right. The linters are getting better, but not everything.\n \n 543\n 01:01:35.150 --> 01:01:47.560\n Dexter Horthy: but, like either, create a biome rule set or an Eslint rule set, or whatever it is, or even just create a prompt that is like, here's a bunch of examples of how we write code that. So the model doesn't have to read entire files, but you capture it succinctly.\n \n 544\n 01:01:47.560 --> 01:02:10.270\n Vaibhav Gupta: Yeah, and to do a little bit of extra leg work to find the models that represent it. And I think this is the same way, if you think about like just hiring a new developer, there's ways to build your Dev team where you're like. People, my dev team will just figure out some coding format and alignment. But if you really care about code quality and want it to be consistent, then you add a linter, you add a formatter, and then it becomes uniform automatically.\n \n 545\n 01:02:10.650 --> 01:02:25.470\n Vaibhav Gupta: So like. And the most ultimate way to do this is the end up using some language like Go, which, like forces like, if you want to export things that has to be capital like developers, don't even get a choice or use black, which is like a very opinionated python format which says, no configuration. It's just the way it is.\n \n 546\n 01:02:25.720 --> 01:02:28.829\n Vaibhav Gupta: and I think the same things apply for like stylistic guidelines.\n \n 547\n 01:02:30.740 --> 01:02:31.319\n Vaibhav Gupta: Does that.\n \n 548\n 01:02:31.320 --> 01:02:32.430\n Jonathan Ng: That makes sense.\n \n 549\n 01:02:34.244 --> 01:02:40.235\n Jonathan Ng: Yeah, I think. There's also like in cursor, for example, there are also cursor rules,\n \n 550\n 01:02:41.220 --> 01:02:46.980\n Jonathan Ng: which I think also help with this, although I haven't really explored a lot of it.\n \n 551\n 01:02:47.290 --> 01:02:48.579\n Jonathan Ng: Person would say.\n \n 552\n 01:02:48.580 --> 01:02:58.070\n Vaibhav Gupta: Yeah, cursor rules are a great way to go do that as well. But I think, like, if you're building an app that generates code. Then you can't use cursor rules. So then you have to build your own equivalent of cursor rules.\n \n 553\n 01:03:00.110 --> 01:03:12.239\n Vaibhav Gupta: That's really, if you're using cursor, then cursor rule should hopefully just fix that for you while cursor does this. Since cursor has built a system like this, they basically added a lot of software on top of their codegen\n \n 554\n 01:03:12.380 --> 01:03:15.420\n Vaibhav Gupta: to make their Cogen more in line with your code base.\n \n 555\n 01:03:16.660 --> 01:03:17.649\n Vaibhav Gupta: Oh, come on.\n \n 556\n 01:03:17.650 --> 01:03:20.830\n Jonathan Ng: That makes sense alright. Thank you.\n \n 557\n 01:03:21.310 --> 01:03:26.130\n Vaibhav Gupta: Alright, thanks, Jonathan. One last question. And then I'm gonna go into this prompt now that I've actually read it\n \n 558\n 01:03:29.520 --> 01:03:30.390\n Vaibhav Gupta: cool.\n \n 559\n 01:03:30.720 --> 01:03:34.520\n Dexter Horthy: Going once going twice, all right. Hack night of Github.\n \n 560\n 01:03:35.200 --> 01:03:35.890\n Vaibhav Gupta: Okay.\n \n 561\n 01:03:36.200 --> 01:03:44.060\n Vaibhav Gupta: So this is a prompt where it seems to be like someone wants to look at Lm, and come up with like some sort of like a plan for the most of this event.\n \n 562\n 01:03:44.840 --> 01:03:51.369\n Dexter Horthy: It looks like the the prompt is basically come up with a plan. And the rest of it is just input context, right?\n \n 563\n 01:03:51.370 --> 01:03:52.510\n Vaibhav Gupta: Yeah, exactly.\n \n 564\n 01:03:52.780 --> 01:03:57.099\n Vaibhav Gupta: So the 1st thing that I'll notice is like, let's just go back and write this prompt\n \n 565\n 01:03:59.357 --> 01:04:03.630\n Vaibhav Gupta: and actually, oh, yeah, plan, dot demo\n \n 566\n 01:04:06.890 --> 01:04:09.240\n Vaibhav Gupta: function, make event.\n \n 567\n 01:04:09.760 --> 01:04:12.959\n Vaibhav Gupta: Well, actually, I'm not gonna actually do this. I don't want this.\n \n 568\n 01:04:13.630 --> 01:04:14.190\n Dexter Horthy: Yeah.\n \n 569\n 01:04:21.290 --> 01:04:25.980\n Vaibhav Gupta: And this thing will make this a better function.\n \n 570\n 01:04:26.960 --> 01:04:30.620\n Vaibhav Gupta: Okay? So the 1st thing I'll notice about this is.\n \n 571\n 01:04:31.030 --> 01:04:35.229\n Vaibhav Gupta: oh, what the heck did. An update. Oh, that's so funny. We have a bug, we have a\n \n 572\n 01:04:37.150 --> 01:04:40.889\n Vaibhav Gupta: that's so funny. We have a bug where com in my.\n \n 573\n 01:04:40.890 --> 01:04:43.719\n Dexter Horthy: Is it coming as like Markdown, front matter or something?\n \n 574\n 01:04:43.720 --> 01:04:49.209\n Vaibhav Gupta: It's like dash, dash, dashes, comments. I think we strip it out that's so funny.\n \n 575\n 01:04:50.290 --> 01:04:51.090\n Dexter Horthy: Yes, I.\n \n 576\n 01:04:51.280 --> 01:04:55.620\n Vaibhav Gupta: So like the 1st thing when it comes to. So let's let's catch everyone else on what this prompt is.\n \n 577\n 01:04:56.210 --> 01:05:02.889\n Vaibhav Gupta: This prompt is pretty simple. It does come up with a plan to make the most of this event, and then you dump the actual event from like Luma or something else out there.\n \n 578\n 01:05:03.150 --> 01:05:09.409\n Vaibhav Gupta: Now. The most intuitive way is to just send that to the prompt and like, if we send the Chat, Gpt, or go, do something\n \n 579\n 01:05:09.580 --> 01:05:11.360\n Vaibhav Gupta: so like if I have.\n \n 580\n 01:05:11.360 --> 01:05:17.659\n Dexter Horthy: By the way, if whoever wrote that prompt is is here, feel free to come off mute and give a little more context around what this is, and what you use it for.\n \n 581\n 01:05:17.660 --> 01:05:35.410\n John Chen: Yeah, so I'm the one who posted it. This is how I you know Luma has, like a hundred events a month in San Francisco, and I don't read them all manually at first, st so I use something like this to try to surface the ones I want to go to, and this how I know about Babel. So you know a pretty crude.\n \n 582\n 01:05:35.410 --> 01:05:35.769\n Dexter Horthy: There you go!\n \n 583\n 01:05:35.770 --> 01:05:40.950\n John Chen: For me, and I just want to make it a little more comprehensive, systemic and all that.\n \n 584\n 01:05:41.120 --> 01:05:48.490\n John Chen: And you know I just don't have an actual process for it, but I know it. Kinda it works for me to make the sense of San Francisco texting.\n \n 585\n 01:05:49.020 --> 01:05:50.870\n Vaibhav Gupta: And I think I could do more with it.\n \n 586\n 01:05:51.600 --> 01:05:56.449\n Vaibhav Gupta: Yeah. So over here, you can see what it come up with. And this is typically what you'd expect out of this sort of thing\n \n 587\n 01:05:56.560 --> 01:06:08.800\n Vaibhav Gupta: that said, what I actually want is, and this is step number one, literally just stop asking the model to actually go do like, spit out the plan as a string, have the model actually spit out a preparation sub for you.\n \n 588\n 01:06:09.240 --> 01:06:13.369\n Vaibhav Gupta: I like what to go do. And when you actually go, do this, let's actually paste.\n \n 589\n 01:06:13.570 --> 01:06:15.329\n Vaibhav Gupta: I'll just copy and paste this in myself.\n \n 590\n 01:06:16.960 --> 01:06:21.110\n Vaibhav Gupta: I think I copied and pasted this example as well. So I'll make this test case\n \n 591\n 01:06:23.490 --> 01:06:25.944\n Dexter Horthy: I like the discord, only lets you copy one time.\n \n 592\n 01:06:26.630 --> 01:06:28.289\n Vaibhav Gupta: I know that's so funny.\n \n 593\n 01:06:32.330 --> 01:06:40.080\n Vaibhav Gupta: Great. So I have this test case now, and when I go run the instead of the model actually spitting this stuff up here. It's actually giving me something a little bit better\n \n 594\n 01:06:40.530 --> 01:06:50.320\n Vaibhav Gupta: of like what I can go talk to. And in this case I have a way, better experience like who I actually should go meet. And I can make this more targeted by simply just changing my schema\n \n 595\n 01:06:50.460 --> 01:06:53.000\n Vaibhav Gupta: class networking.\n \n 596\n 01:06:53.780 --> 01:06:54.800\n Vaibhav Gupta: Oh, God!\n \n 597\n 01:06:55.320 --> 01:07:00.610\n Vaibhav Gupta: Class. Networking opportunity.\n \n 598\n 01:07:04.880 --> 01:07:18.020\n Vaibhav Gupta: Okay. Name, season, string, value, value, high medium, low description. How valuable the.\n \n 599\n 01:07:18.530 --> 01:07:20.590\n Dexter Horthy: Yeah, we'll we'll push all this. Go, John.\n \n 600\n 01:07:20.590 --> 01:07:29.260\n Vaibhav Gupta: The person is to myself and my career polls.\n \n 601\n 01:07:29.810 --> 01:07:42.229\n Dexter Horthy: Yeah, the other thing, I think, would benefit a lot here is like a lot more context about me and who I am, although I guess if you're probably pasting this into Chat Gpt, then you have your memory and stuff at play to kind of like, give that grounding.\n \n 602\n 01:07:42.750 --> 01:07:53.100\n Vaibhav Gupta: So the name main thing that you'll notice here is I, I'm actually gonna change this. I'm gonna make this a lot better. I'm gonna say that this is I wanna meet these people value. And then it's gonna dump out the reason for why.\n \n 603\n 01:07:53.380 --> 01:07:59.349\n Vaibhav Gupta: And you notice that actually changed out a lot of the more general, generally specific ones like this was very\n \n 604\n 01:08:00.030 --> 01:08:04.559\n Vaibhav Gupta: like random, but this is a lot more pointed, oriented. I can go act on this.\n \n 605\n 01:08:04.700 --> 01:08:07.179\n Vaibhav Gupta: What else I can do here is, I can say, like.\n \n 606\n 01:08:07.390 --> 01:08:09.880\n Vaibhav Gupta: I can actually change this. I like entity\n \n 607\n 01:08:13.960 --> 01:08:26.500\n Vaibhav Gupta: last company, right company, name, last person, type.\n \n 608\n 01:08:27.029 --> 01:08:30.369\n Vaibhav Gupta: And see you want this.\n \n 609\n 01:08:30.960 --> 01:08:45.810\n Vaibhav Gupta: And now, when I go run this, it should actually spit out what I actually want. So now, I can actually go like specifically look these up. And I can build a small little ui around this like a react component that actually renders these in with like Linkedin searches and follow up sequences on top of that.\n \n 610\n 01:08:46.270 --> 01:08:58.950\n Vaibhav Gupta: So then I can just go ahead and say, Oh, here's a link to the company's URL. Here's who they are, and here's how they are. And this is just like Aiml. Speakers cool. No one specific was highlighted on there. So I don't actually have, like anyone ambiguous people are ambiguous. There.\n \n 611\n 01:08:59.420 --> 01:09:23.650\n Dexter Horthy: But if you put 1st name last name you could also probably force it to like it wouldn't even output that right like if you. Wanna if you want to drive the output to the point where it's like, Okay, I only want things that are actually useful. I don't want this kind of like hallucinating, sloppy like talk to aiml speakers like, Okay, that's bullshit, like I. I only want like you to pull out people with actual names. So it's like, if there was a speaker name in the description of like, this person will be speaking, then it could go tell you some things about them.\n \n 612\n 01:09:28.160 --> 01:09:31.730\n Vaibhav Gupta: And we can guarantee that at least the 1st name or the last name exists.\n \n 613\n 01:09:32.340 --> 01:09:34.890\n Vaibhav Gupta: and then all other entities will just get dropped.\n \n 614\n 01:09:36.420 --> 01:09:37.999\n Vaibhav Gupta: So we still get these.\n \n 615\n 01:09:38.370 --> 01:10:04.459\n Vaibhav Gupta: But then we they actually just get dropped from our final parsing, because, like, it doesn't meet the constraint that we need, which is 1st and last name need to actually exist. So even if they all generates it, you can drop it. But the whole point of this is, instead of actually having the model spit out the string. What I really did is I focus on what I care about what I want to see and what I want to personally derive out of this prompt, which is, I think, what John you're trying to do is like, see if things are going to help you like grow out of these events.\n \n 616\n 01:10:04.590 --> 01:10:09.549\n Vaibhav Gupta: So then I would just focus the specific stuff on here to say, like.\n \n 617\n 01:10:09.970 --> 01:10:14.919\n Vaibhav Gupta: focus on how it helps me and myself. It is to myself and my career, goals.\n \n 618\n 01:10:15.250 --> 01:10:23.969\n Dexter Horthy: Yeah, guide the reasoning with as much context as possible. And I bet if you took this Json object and dropped into V 0, you could make a nice ui for this, and you know 60 seconds.\n \n 619\n 01:10:24.620 --> 01:10:30.690\n Vaibhav Gupta: Oh, yeah, I bet this is same in line with this.\n \n 620\n 01:10:31.170 --> 01:10:33.670\n Vaibhav Gupta: Make a ui, for\n \n 621\n 01:10:41.910 --> 01:10:43.610\n Vaibhav Gupta: I'll probably go do something.\n \n 622\n 01:10:45.025 --> 01:10:52.400\n Vaibhav Gupta: And I'll go build some out something ui for me. And now we have a full app that we can just go use directly without having to think about it.\n \n 623\n 01:10:54.200 --> 01:10:56.439\n Vaibhav Gupta: with small little rendering stuff as well.\n \n 624\n 01:10:57.120 --> 01:10:58.909\n Vaibhav Gupta: Come on. This takes a while.\n \n 625\n 01:10:59.440 --> 01:11:01.520\n Vaibhav Gupta: and then you can. Do you want with your app?\n \n 626\n 01:11:04.200 --> 01:11:05.319\n Dexter Horthy: We got time for one more prompt\n \n 627\n 01:11:09.200 --> 01:11:11.120\n Dexter Horthy: saw someone else typing in.\n \n 628\n 01:11:12.540 --> 01:11:13.579\n sahil: Sorry. Go ahead.\n \n 629\n 01:11:13.850 --> 01:11:16.700\n sahil: Can I just drop the prompt in the chat, or should I.\n \n 630\n 01:11:16.700 --> 01:11:20.709\n Vaibhav Gupta: I'll probably be too long, but you will have to do it in the discord sadly.\n \n 631\n 01:11:20.710 --> 01:11:21.999\n sahil: Oh, yeah, yeah, okay. Cool.\n \n 632\n 01:11:22.000 --> 01:11:28.049\n Dexter Horthy: Prashant had another one as well. That was answering questions with like verbosity, and things like that.\n \n 633\n 01:11:28.050 --> 01:11:31.960\n Prashanth Rao: Yeah. So so actually, you kind of answered many of these in the previous example.\n \n 634\n 01:11:31.960 --> 01:11:32.809\n Vaibhav Gupta: Have a nice day.\n \n 635\n 01:11:33.510 --> 01:11:34.150\n Dexter Horthy: Okay.\n \n 636\n 01:11:36.336 --> 01:11:42.150\n Vaibhav Gupta: And then we'll do the last one really fast. While we're out here, and let's while while visa is loading.\n \n 637\n 01:11:43.540 --> 01:11:47.350\n Vaibhav Gupta: I hate this. I. This is the part I hate the most about. V. 0, it takes so long.\n \n 638\n 01:11:49.120 --> 01:11:50.050\n Vaibhav Gupta: Okay, well.\n \n 639\n 01:11:50.050 --> 01:11:52.090\n Dexter Horthy: Lot of deterministic code.\n \n 640\n 01:11:53.280 --> 01:11:57.890\n Vaibhav Gupta: You are tasked with a video editing plan. Okay, I'm gonna.\n \n 641\n 01:11:57.890 --> 01:11:58.560\n Dexter Horthy: Sick.\n \n 642\n 01:11:59.180 --> 01:12:05.699\n Vaibhav Gupta: Okay, I'm just gonna go do this alright. So right over here. By the way, we can see this.\n \n 643\n 01:12:06.730 --> 01:12:15.569\n Vaibhav Gupta: So now it has a fun, little ui for me to go. Do build this in not not to edit, just to view the final outcome.\n \n 644\n 01:12:16.460 --> 01:12:17.170\n Vaibhav Gupta: Oh.\n \n 645\n 01:12:21.990 --> 01:12:26.050\n Dexter Horthy: Oh, do you find the frowny face makes Vercel make better content.\n \n 646\n 01:12:26.220 --> 01:12:28.779\n Vaibhav Gupta: No, I was just annoyed that it did the wrong thing.\n \n 647\n 01:12:30.070 --> 01:12:30.770\n Vaibhav Gupta: Video.\n \n 648\n 01:12:30.770 --> 01:12:33.749\n Dexter Horthy: Well, maybe if you went and read your prompt.\n \n 649\n 01:12:35.320 --> 01:12:39.409\n Vaibhav Gupta: That. Well, I can't read the V 0 prompt. So it's a little bit harder.\n \n 650\n 01:12:40.351 --> 01:12:46.129\n Vaibhav Gupta: Insert script expert here. What is this trying to do. Do you have your? Do you have your data models and everything else on here?\n \n 651\n 01:12:48.160 --> 01:13:01.359\n Vaibhav Gupta: If you don't, then I I can try. But it's harder to do without like actual function types, because this prompt is a little bit more complex. But let me just give you some general guidelines that I see right off this right off my top right off the top of my head\n \n 652\n 01:13:01.780 --> 01:13:06.779\n Vaibhav Gupta: when I read this from the 1st thing that I see is.\n \n 653\n 01:13:07.220 --> 01:13:11.779\n Vaibhav Gupta: I don't actually think you need all this data like this is a lot more redundant.\n \n 654\n 01:13:12.000 --> 01:13:26.370\n Vaibhav Gupta: You're I'm not sure if this is all a system prompt or a user prompt. But when I go look at this, the 1st thing that I see is that this is not it's like mixing and matching both the content and the instructions all over the place.\n \n 655\n 01:13:26.580 --> 01:13:34.229\n Vaibhav Gupta: because, like you're listing out your, you have instructions, content instructions, content, instructions.\n \n 656\n 01:13:35.070 --> 01:13:38.270\n Vaibhav Gupta: instructions. It looks like more content.\n \n 657\n 01:13:38.580 --> 01:13:40.580\n Dexter Horthy: Oh, that's this is the output schema.\n \n 658\n 01:13:40.580 --> 01:13:43.810\n Vaibhav Gupta: Oh, this is the output format. Yeah, so it looks like you're.\n \n 659\n 01:13:43.810 --> 01:13:45.370\n Dexter Horthy: But then there's more instructions.\n \n 660\n 01:13:45.370 --> 01:13:49.120\n Vaibhav Gupta: Yeah, it just feels like you're we're mixing a lot of instructions, and it doesn't read\n \n 661\n 01:13:49.685 --> 01:13:53.270\n Vaibhav Gupta: in the way that I would write this if I were a human.\n \n 662\n 01:13:53.470 --> 01:14:10.579\n Vaibhav Gupta: And we're also writing a lot of things that's like you are a blah blah blah like the model doesn't care who it is, it just has to know the job it wants to do. You don't need to tell it. This is my role. If you notice in any of the prompts. I didn't. I didn't like. I wasn't like you're a senior engineer that does blah blah blah. I just like write the code from this prompt.\n \n 663\n 01:14:11.170 --> 01:14:13.719\n Vaibhav Gupta: That's like the 1st thing I would do. So let's just like.\n \n 664\n 01:14:14.090 --> 01:14:19.030\n Vaibhav Gupta: there you go. And, by the way, for people generating this, now, you can generate this kind of ui automatically from here.\n \n 665\n 01:14:19.380 --> 01:14:32.990\n Vaibhav Gupta: and this would be super super easy for me to go coach, and then I could put buttons on here that I'll call like Enrich, which calls another Lm function that finds all the data about that company using like a research thing that I go built. Sorry I context which really fast.\n \n 666\n 01:14:35.130 --> 01:14:42.379\n Vaibhav Gupta: But let me go back really fast and start a new chat thing make this prompt better.\n \n 667\n 01:14:42.770 --> 01:14:50.440\n Vaibhav Gupta: No. Xml and the error rendering Markdown is the thing that hopefully we'll fix in.\n \n 668\n 01:14:51.050 --> 01:15:09.330\n Dexter Horthy: Yeah, prashant the the ura. We were just talking about this before the episode that, like asking models to adopt a role is, I think the best prompt engineers out there have been talking for months about, if not longer, about how that doesn't really work very well or like. It doesn't have that much effect on the output.\n \n 669\n 01:15:09.770 --> 01:15:17.339\n sahil: The funny thing is that this comes right out of Claude from generation as well.\n \n 670\n 01:15:19.330 --> 01:15:20.949\n Vaibhav Gupta: I bet this is my.\n \n 671\n 01:15:20.950 --> 01:15:25.029\n Dexter Horthy: Because there's a lot of data in the training set doesn't mean it's correct or good data.\n \n 672\n 01:15:25.480 --> 01:15:29.839\n Vaibhav Gupta: Yeah, just like the most code out there is kind of shit you probably shouldn't follow most code.\n \n 673\n 01:15:31.045 --> 01:15:31.600\n Vaibhav Gupta: But\n \n 674\n 01:15:33.300 --> 01:15:40.390\n Vaibhav Gupta: a lot of code is still very good, and you should follow that. But it's all about finding the right segments. So in this case the 1st thing I do is like, get rid of this.\n \n 675\n 01:15:42.480 --> 01:15:50.800\n Vaibhav Gupta: create a segmentation plan for the following trip. Breaking logic for each segment, ensure it contains complete thought or idea. Estimate a reasonable time. Consider the pacing\n \n 676\n 01:15:51.445 --> 01:15:55.130\n Vaibhav Gupta: and it's important to kind of like, describe what these mean\n \n 677\n 01:15:55.540 --> 01:16:04.009\n Vaibhav Gupta: cause it probably doesn't actually know. And I I have no idea what it actually means for fast, slower medium like, I'm just it just made stuff up. You need to go and actually understand your own.\n \n 678\n 01:16:04.550 --> 01:16:07.780\n Vaibhav Gupta: I think, for that and like, if you.\n \n 679\n 01:16:07.780 --> 01:16:19.930\n Dexter Horthy: Or you could even force it in the schema. Right? You could be like, Okay, cool. I know how long this is, and I can say. I know I want exactly, you know. Do it in code, and say, I want exactly 40 cuts, because I want 30 to 40 cuts versus something else.\n \n 680\n 01:16:20.400 --> 01:16:22.510\n Vaibhav Gupta: I want a.\n \n 681\n 01:16:23.390 --> 01:16:25.750\n Dexter Horthy: Because then we're not making the model count.\n \n 682\n 01:16:35.280 --> 01:16:35.870\n Dexter Horthy: There you go.\n \n 683\n 01:16:35.870 --> 01:16:38.499\n Vaibhav Gupta: And instead of actually outputting all the stuff.\n \n 684\n 01:16:39.240 --> 01:16:42.119\n Vaibhav Gupta: I will actually just literally tell the model to go. Do this.\n \n 685\n 01:16:42.230 --> 01:16:50.589\n Vaibhav Gupta: I will literally tell it exactly what I want the pacing to be. Instead of describing all the pacings, I will specifically only admit the pacing that's actually relevant to the model.\n \n 686\n 01:16:50.880 --> 01:17:00.549\n Dexter Horthy: And that's the same thing, the user and the program. See a single world fast. But then you translate that into more verbose instructions, but only the Llm. Sees that part.\n \n 687\n 01:17:00.740 --> 01:17:07.150\n Vaibhav Gupta: And the Lm. Is not seeing everything else. So if I change this from slow to fast, it sees this one, whereas in this one it sees slow.\n \n 688\n 01:17:08.820 --> 01:17:12.369\n Vaibhav Gupta: right? So now it's able to actually go. Do this along the way.\n \n 689\n 01:17:13.204 --> 01:17:14.859\n Vaibhav Gupta: And now, when I.\n \n 690\n 01:17:14.860 --> 01:17:15.769\n Dexter Horthy: You can run it.\n \n 691\n 01:17:16.060 --> 01:17:17.540\n Vaibhav Gupta: Why not? Yeah? Why not?\n \n 692\n 01:17:21.090 --> 01:17:25.060\n Vaibhav Gupta: And I don't even know what transition is like. If transitions have a separate cut\n \n 693\n 01:17:25.670 --> 01:17:27.390\n Vaibhav Gupta: like, sure, let's do that.\n \n 694\n 01:17:28.520 --> 01:17:30.670\n Vaibhav Gupta: Let's let's just run this way.\n \n 695\n 01:17:33.390 --> 01:17:38.660\n Vaibhav Gupta: and it's able to go do this. Now. Duration is kind of is kind of misleading, and the description is kind of\n \n 696\n 01:17:40.470 --> 01:17:42.000\n Vaibhav Gupta: 30 seconds.\n \n 697\n 01:17:42.460 --> 01:17:43.770\n Vaibhav Gupta: I'm gonna change this.\n \n 698\n 01:17:46.690 --> 01:17:47.680\n Vaibhav Gupta: Alias.\n \n 699\n 01:17:53.430 --> 01:17:59.470\n sahil: I don't think we need duration, because the duration is essentially the content, so we can skip it.\n \n 700\n 01:17:59.470 --> 01:18:07.730\n Vaibhav Gupta: Yes, but you might benefit from actually having a duration in there, just so that a model can like plan\n \n 701\n 01:18:08.080 --> 01:18:09.260\n Vaibhav Gupta: for each segment.\n \n 702\n 01:18:09.870 --> 01:18:11.839\n Vaibhav Gupta: It's the same thing. It's like.\n \n 703\n 01:18:11.840 --> 01:18:13.189\n Dexter Horthy: Duration. Kind of Right.\n \n 704\n 01:18:13.490 --> 01:18:29.010\n Vaibhav Gupta: Cause you have. You have a thing in there where you're thinking about prompting, but you want the model to also be thinking about duration like the amount of inference it has. It's about the amount caches. Why do we have a Redis cache? Not because we can't go to the database because we don't want to go to the database all the time.\n \n 705\n 01:18:29.180 --> 01:18:33.159\n Vaibhav Gupta: Why are you putting duration here? The model can just like kind of think about this.\n \n 706\n 01:18:33.550 --> 01:18:37.769\n Vaibhav Gupta: Now we see that this content is like pretty short form.\n \n 707\n 01:18:37.940 --> 01:18:41.000\n Vaibhav Gupta: which is totally fine. But if you want this to be the full content.\n \n 708\n 01:18:41.280 --> 01:18:42.700\n Vaibhav Gupta: then we can just do this.\n \n 709\n 01:18:43.270 --> 01:18:47.150\n Vaibhav Gupta: We can. We can guide the model to generate more text, use.\n \n 710\n 01:18:47.150 --> 01:18:58.189\n Dexter Horthy: I think your input test case is really is really small. I think this is actually the right, the right text straight from the input. Thing. So like, we need like a way longer script to really test this. Anyways.\n \n 711\n 01:18:58.830 --> 01:19:00.909\n sahil: Can I drop in a can I drop in a script?\n \n 712\n 01:19:01.020 --> 01:19:01.660\n sahil: I have one.\n \n 713\n 01:19:01.660 --> 01:19:02.510\n Vaibhav Gupta: Yeah, dropping us.\n \n 714\n 01:19:02.510 --> 01:19:03.679\n Dexter Horthy: Yes, that's a script.\n \n 715\n 01:19:05.410 --> 01:19:06.540\n Dexter Horthy: Fuck. Yeah.\n \n 716\n 01:19:07.240 --> 01:19:09.100\n Dexter Horthy: On the fucking. AI that works.\n \n 717\n 01:19:09.100 --> 01:19:09.749\n sahil: There you go.\n \n 718\n 01:19:10.660 --> 01:19:12.140\n sahil: History of computing.\n \n 719\n 01:19:13.610 --> 01:19:19.080\n Dexter Horthy: I like this, we should do this more. We should. We should take people's real problems and solve them.\n \n 720\n 01:19:19.820 --> 01:19:20.699\n Vaibhav Gupta: Let's run it\n \n 721\n 01:19:26.020 --> 01:19:26.840\n Vaibhav Gupta: right?\n \n 722\n 01:19:28.080 --> 01:19:29.819\n Vaibhav Gupta: So you can actually see what it did.\n \n 723\n 01:19:30.040 --> 01:19:32.799\n Vaibhav Gupta: It actually spit out all the content as a line.\n \n 724\n 01:19:34.500 --> 01:19:37.689\n sahil: But the duration seconds is 60 for everything now.\n \n 725\n 01:19:37.750 --> 01:19:41.309\n Dexter Horthy: Do you still want it to be a list by Bob? Or do you want to just be a single strength.\n \n 726\n 01:19:42.059 --> 01:19:47.280\n Vaibhav Gupta: We can. Oh, sorry, yes, estimated\n \n 727\n 01:19:48.780 --> 01:19:54.030\n Vaibhav Gupta: seconds. Let's give it some description like, what? How? How do you estimate duration?\n \n 728\n 01:19:57.253 --> 01:20:04.980\n sahil: Let's say every 1,000 characters is a minute or 60 seconds, or.\n \n 729\n 01:20:05.850 --> 01:20:08.709\n Dexter Horthy: Oh, are we gonna make the model count characters.\n \n 730\n 01:20:09.870 --> 01:20:12.009\n Vaibhav Gupta: Every like. Let's let's try this. I want that.\n \n 731\n 01:20:12.010 --> 01:20:18.490\n sahil: Every every so typically every 1 20 boats per minute. So\n \n 732\n 01:20:19.027 --> 01:20:22.399\n sahil: there you can count words or characters. I don't know.\n \n 733\n 01:20:23.200 --> 01:20:26.850\n Vaibhav Gupta: Words per minute, what is average\n \n 734\n 01:20:28.870 --> 01:20:31.249\n Vaibhav Gupta: right? And we might actually find that like, hey.\n \n 735\n 01:20:31.370 --> 01:20:36.399\n Vaibhav Gupta: if we do this, it's actually when we do slower pacing. It's gonna be a little bit. It's about a hundred words per minute.\n \n 736\n 01:20:38.120 --> 01:20:43.840\n Vaibhav Gupta: If we do this, it's gonna be like a hundred 20, and we do fast. It's gonna be like a hundred 50.\n \n 737\n 01:20:44.490 --> 01:20:53.829\n Vaibhav Gupta: So you might actually like find that it's useful to actually guide the model appropriately for the different use cases, because that's what I would do. I would I would have a slightly talk faster voice in general, not just like the pacing.\n \n 738\n 01:20:57.480 --> 01:21:03.769\n Dexter Horthy: It would be interesting to also have this like start suggesting like, Hey, what do you want to show on the screen during this cut? Right.\n \n 739\n 01:21:04.360 --> 01:21:05.900\n Vaibhav Gupta: Exactly so now.\n \n 740\n 01:21:05.900 --> 01:21:08.140\n Dexter Horthy: Do like a image, search and pull that in.\n \n 741\n 01:21:08.530 --> 01:21:11.119\n Vaibhav Gupta: Background image. So let's do that.\n \n 742\n 01:21:12.690 --> 01:21:21.849\n Dexter Horthy: This would be a fun building, like an example of this end to end of like, how to just like generate automated video content from little scripts, an end to end content. Pipeline.\n \n 743\n 01:21:23.560 --> 01:21:26.769\n sahil: To make you can come, help me build my my company.\n \n 744\n 01:21:27.440 --> 01:21:31.762\n Dexter Horthy: I was gonna say, yeah, we have to be careful not to build a open source competitor to sail.\n \n 745\n 01:21:31.990 --> 01:21:34.540\n sahil: I would love for that.\n \n 746\n 01:21:37.995 --> 01:21:44.529\n Vaibhav Gupta: a description description, that is, that is.\n \n 747\n 01:21:44.760 --> 01:22:00.249\n sahil: So I have a couple of questions over here. So earlier in the example you were, you were showing how we can create indexes, and to to make sure that we are not spitting out so much text and saving tokens. I know, like, obviously, this is slightly\n \n 748\n 01:22:01.110 --> 01:22:06.819\n sahil: different case where we have to spit out the text. Are there any tips or tricks we could use to\n \n 749\n 01:22:08.050 --> 01:22:12.209\n sahil: do that index thing in here in any way, shape or form?\n \n 750\n 01:22:12.850 --> 01:22:21.669\n Vaibhav Gupta: Well, I don't actually know if you have to spit out the text and form like, honestly, you could just make this a lookup table based on strings like you just spit out every line, every sentence into itself.\n \n 751\n 01:22:22.560 --> 01:22:25.640\n Vaibhav Gupta: As like a thing, and then you could have the model spit out like a span.\n \n 752\n 01:22:26.700 --> 01:22:33.580\n Vaibhav Gupta: so like from dialogue, one to dialog. 7. Do this dialogue one to 3, and they'll naturally find breakpoints\n \n 753\n 01:22:34.040 --> 01:22:52.539\n Vaibhav Gupta: in the dialog. And now you can go. Do that. You can ask. You can build a separate pipeline that says, if you really care about like cost and latency, I would build a separate pipeline that says, Given all these dialogues, what is the most intuitive breakpoints to inject into here, and then you go get, generate the background, image and everything off of that.\n \n 754\n 01:22:53.260 --> 01:22:59.359\n Vaibhav Gupta: So you can solve this problem in many different ways, but it's more about identifying the indexes of where the breakpoint should be, for where transition should happen.\n \n 755\n 01:23:00.290 --> 01:23:10.490\n Dexter Horthy: Oh, so it becomes similar to kind of almost the diarization where maybe you just wanted to output like the first, st like the the biggest, like the smallest unique chunk that like offsets the text. There.\n \n 756\n 01:23:10.860 --> 01:23:13.059\n Vaibhav Gupta: Exactly cool. Exactly. Where would you go?\n \n 757\n 01:23:15.150 --> 01:23:15.690\n Dexter Horthy: Cool.\n \n 758\n 01:23:15.690 --> 01:23:27.579\n Dexter Horthy: We're 90 min, we should probably wrap it up. This was super fun. Y'all. Thank you so much by Bob for sharing your prompting wisdom for those of you who made it to the very end. Congrats. Well, there's no prize except that you got to learn more.\n \n 759\n 01:23:27.790 --> 01:23:35.251\n Dexter Horthy: and we will push all the code and the video, and we'll send out a blast. And come catch us next week and\n \n 760\n 01:23:35.680 --> 01:23:44.499\n Dexter Horthy: we should figure out what we're gonna do. Next week we have a we have a, we have a long backlog of things, but we're gonna figure it out, and we'll we'll we'll update y'all with what's coming next. So thanks, everybody.\n \n 761\n 01:23:45.220 --> 01:23:45.730\n Vaibhav Gupta: Thanks for joining.\n \n 762\n 01:23:46.200 --> 01:23:47.110\n Aaron Lehman | LifeLensAR: Thanks.

We've seen this in like SQL generation. And maybe this is a tactic we can talk about today. But like we've seen it like SQL. Generation. Okay, have the model generate a Json object that can be determined turned into a SQL. Query for Svgs. The Tl. Draw. Guy was talking about this at AI engineer last week have the model generate a structured object that it's good at writing, that then deterministic code can turn into an Svg. And I think.\n \n 2\n 00:00:23.140 --> 00:00:35.660\n Dexter Horthy: have the model generate code that then you can like bake. It's like creating different views of the same thing. And then, once that's baked, then you can deterministically execute that code with the programming Runtime.\n \n 3\n 00:00:36.470 --> 00:00:37.040\n Vaibhav Gupta: Yeah.\n \n 4\n 00:00:37.240 --> 00:00:47.522\n Vaibhav Gupta: alright. Well, with that, let's get started. My name is Bye, Bob. This is Dexter. We've been doing this every week for the last few weeks now.\n \n 5\n 00:00:47.890 --> 00:00:49.769\n Dexter Horthy: Months we started in March. Dude.\n \n 6\n 00:00:49.770 --> 00:00:54.679\n Vaibhav Gupta: Oh, wow, yes, but we took a break, so I don't know if that counts. The break is where I define the line.\n \n 7\n 00:00:55.143 --> 00:01:07.880\n Vaibhav Gupta: But regardless. The whole point of this, these episodes of AI that works is to talk about real practical AI applications where we don't just talk about high level stuff, but really try and show the code behind how things work.\n \n 8\n 00:01:08.230 --> 00:01:32.249\n Vaibhav Gupta: We've talked about a bunch of things in the past from Mcp. Servers with 10,000 plus tools to 12 factor agents by Dexter all the way to human. Learn how to use humans as tools, and then just really how to think about prompts. But today I think we want to do something that was different. It's going to be a lot more varied in conversation than our previous conversations which are all about focusing on one depth thing. Today, we want to talk about just prompting as a whole.\n \n 9\n 00:01:32.580 --> 00:01:37.440\n Vaibhav Gupta: Nothing. Fancy, just plain old prompting, and many of you\n \n 10\n 00:01:38.244 --> 00:01:43.190\n Vaibhav Gupta: and actually, Dexter, do you want to give a little precursor while I get this screen recording up.\n \n 11\n 00:01:43.430 --> 00:02:01.810\n Dexter Horthy: Well, I think, like many of the things that we end up talking about, you can take like what is a really simple problem that folks kind of can look at and just say, Oh, that's solved, like like classification. It's like, Okay, I know how to pass the Lm. A list of labels and get it to output one of those labels with structured outputs or something like that. And then you go and you look under the hood, and it's like, Oh.\n \n 12\n 00:02:01.810 --> 00:02:30.180\n Dexter Horthy: like, actually, there's a lot of room where I thought the ceiling was like, Okay, here's the techniques. Here's how you do it. There's so much more room to basically open up the box and rip out all the wires and redo everything, and like engineer it to get much better results. And I think, like the core of that is always prompting. And so I'm really excited today to learn about both, like just some basic techniques framed in terms of certain types of problems.\n \n 13\n 00:02:30.180 --> 00:02:48.749\n Dexter Horthy: And I think today one of the things that it will be cool is we're not going to talk as much about like one big overarching problem, like we usually do. We're just going to give you a grab bag of small tips and tricks that are reusable across problem spaces, and like lower level advice that you can apply to lots of problems.\n \n 14\n 00:02:48.750 --> 00:03:01.780\n Dexter Horthy: And I think hopefully, if folks are down, I think we put a thread in the boundary discord. If anyone wants to share their prompts. The most I've ever learned about prompt engineering is showing 5 of AI applications that I've written.\n \n 15\n 00:03:01.780 --> 00:03:05.830\n Dexter Horthy: and having him roast my prompt and tell me what we're doing wrong.\n \n 16\n 00:03:06.923 --> 00:03:12.929\n Vaibhav Gupta: Actually, with that. What I'll do is in the thing in here. I will actually just post a link to this thread\n \n 17\n 00:03:13.190 --> 00:03:18.010\n Vaibhav Gupta: copy thread, and I'll post this in chat.\n \n 18\n 00:03:18.200 --> 00:03:19.090\n Vaibhav Gupta: If\n \n 19\n 00:03:19.507 --> 00:03:33.520\n Vaibhav Gupta: anyone wants, they're welcome to post their prompts that they want to share. This will be recorded and like. Just post it on here. We'll fix your prompts at the end, and we'll just show you how we would think about them doesn't mean that they'll necessarily get better. It might just give you another technique or 2.\n \n 20\n 00:03:33.940 --> 00:03:44.230\n Vaibhav Gupta: But with that, let's go into the topic cracking the prompting interview. I think prompting is literally like software engineering. And we're just gonna use the same techniques to do a couple of things off the bat.\n \n 21\n 00:03:44.350 --> 00:03:49.830\n Vaibhav Gupta: So let's start off with a very common problem that I always see, which is always\n \n 22\n 00:03:49.950 --> 00:03:53.450\n Vaibhav Gupta: the 1st one that I'm going to talk about, which is like labels.\n \n 23\n 00:03:54.350 --> 00:03:59.060\n Vaibhav Gupta: And this I think the most common example of this problem that I see is citations.\n \n 24\n 00:03:59.240 --> 00:04:10.120\n Vaibhav Gupta: So imagine that I have a prompt, my prompt will have a bunch of text that I refer to it, and for the context of rag with the rag, I will have it. Give me like the URL, or something attached to it.\n \n 25\n 00:04:11.010 --> 00:04:12.739\n Vaibhav Gupta: and I'll have a bunch of these\n \n 26\n 00:04:13.670 --> 00:04:22.180\n Vaibhav Gupta: along the way. So I'd like a URL with some data. And then I want to go get that. And somehow, in my answer. I want the Llm. To give me out. The URL.\n \n 27\n 00:04:23.600 --> 00:04:24.240\n Vaibhav Gupta: This\n \n 28\n 00:04:24.760 --> 00:04:30.110\n Vaibhav Gupta: is this a problem that I resonates with this couple of people? Does anyone have ideas for how we could make this better.\n \n 29\n 00:04:34.630 --> 00:04:38.340\n Vaibhav Gupta: If not, we'll just go right into it. If today's session is, gonna be.\n \n 30\n 00:04:38.340 --> 00:04:42.840\n Dexter Horthy: Are you? Gonna are you gonna replace the URL with a sentinel token.\n \n 31\n 00:04:43.630 --> 00:04:53.659\n Vaibhav Gupta: Kind of, yeah, exactly. Because what I want is, I want the answer that we over here to be an answer. But I want to include the citations that are that remap to that specific thing.\n \n 32\n 00:04:54.080 --> 00:05:01.790\n Vaibhav Gupta: Now, the problem is, as we all know, Urls can be really, really funky, like just the URL, for this Excalibrop is, I don't know. Let me see if I can share one\n \n 33\n 00:05:02.440 --> 00:05:06.950\n Vaibhav Gupta: like if I go to like. I don't know the random browser page. I probably have something open.\n \n 34\n 00:05:09.960 --> 00:05:12.660\n Vaibhav Gupta: Where'd it go? Sorry\n \n 35\n 00:05:14.850 --> 00:05:27.049\n Vaibhav Gupta: if I just go to like, for example, our Youtube channel. Let me just show some of these videos, these Urls are basically you. I could have this as a citation URL for my model. And let's just take a look at what it would mean for the model to generate this.\n \n 36\n 00:05:28.430 --> 00:05:34.279\n Vaibhav Gupta: Let's just go look at the Tokenizer, because I think this is the most important thing to think about. If a model can generate something accurately or not.\n \n 37\n 00:05:34.790 --> 00:05:56.929\n Vaibhav Gupta: this is what the model has to generate. There's a bunch of tokens. So these tokens make sense. It can probably do this. Youtube is a single token dot, Youtube is a single token. That's kind of interesting. Actually, I learned that today watch a single token. We're good question. Mark V is a single token which also probably makes sense, because Youtube probably is a predominant force in the tokenizer for some reason. But everything else here breaks down.\n \n 38\n 00:05:57.290 --> 00:05:58.390\n Vaibhav Gupta: This ends up.\n \n 39\n 00:05:58.390 --> 00:05:59.389\n Dexter Horthy: And this is.\n \n 40\n 00:05:59.750 --> 00:06:08.299\n Dexter Horthy: there's like models can generate a string. If you type in that string, you say, Hey, model, make this string for me, it's going to make it. But your point is basically that like\n \n 41\n 00:06:08.630 --> 00:06:17.549\n Dexter Horthy: the more tokens that you're asking the model to generate accurately the more kind of effort it has to put on that, and the the less likely it's going to get it right.\n \n 42\n 00:06:18.020 --> 00:06:21.570\n Vaibhav Gupta: Exactly so in order for the model to get this part of the URL correct\n \n 43\n 00:06:21.820 --> 00:06:33.830\n Vaibhav Gupta: specifically, it has to generate 10 tokens perfectly. If we remove this part, let's assume it'll get question. Mark V. Correct. It has to get 8 tokens perfectly correct. If it messes up in any of these, it becomes a useless link.\n \n 44\n 00:06:34.580 --> 00:06:37.750\n Vaibhav Gupta: So how can we change that? Well, we can do something really, really simple.\n \n 45\n 00:06:38.310 --> 00:06:41.279\n Vaibhav Gupta: And I will just use Youtube along the way.\n \n 46\n 00:06:41.770 --> 00:06:44.350\n Vaibhav Gupta: And I'll write a basic prompt that does this\n \n 47\n 00:06:44.630 --> 00:06:49.480\n Vaibhav Gupta: and tries to go about this whoops.\n \n 48\n 00:06:50.450 --> 00:06:56.410\n Vaibhav Gupta: So we're going to write a question, new file like labels. Dot, Aml.\n \n 49\n 00:06:57.300 --> 00:07:02.240\n Vaibhav Gupta: I'm gonna have a function that's gonna say, given like answer question.\n \n 50\n 00:07:02.670 --> 00:07:08.490\n Vaibhav Gupta: I'm gonna say, here's a question. I'm gonna give it a list of links or content.\n \n 51\n 00:07:14.860 --> 00:07:19.480\n Vaibhav Gupta: I'll say like this will have like a URL, which will be a string\n \n 52\n 00:07:19.930 --> 00:07:22.450\n Vaibhav Gupta: and then content, which would be a string. And then\n \n 53\n 00:07:23.900 --> 00:07:37.890\n Vaibhav Gupta: what? What we'll return. Here is some answer, and then citations sharing array at definition list of Urls\n \n 54\n 00:07:39.270 --> 00:07:41.579\n Vaibhav Gupta: that are relevant.\n \n 55\n 00:07:41.700 --> 00:07:55.400\n Vaibhav Gupta: Okay, open AI Gpt. 4. 0, great and ctx dot output format.\n \n 56\n 00:07:56.690 --> 00:08:01.169\n Vaibhav Gupta: Sorry I'm on a live prompt. So I'm gonna try and be as fast as possible.\n \n 57\n 00:08:01.910 --> 00:08:03.950\n Vaibhav Gupta: All user question.\n \n 58\n 00:08:04.910 --> 00:08:11.539\n Dexter Horthy: Okay. So output format is, you're telling it how to output the answer.\n \n 59\n 00:08:12.530 --> 00:08:13.430\n Vaibhav Gupta: Exactly.\n \n 60\n 00:08:13.950 --> 00:08:18.729\n Dexter Horthy: And you're and you're putting the output format and the relevant content into the system prompt.\n \n 61\n 00:08:19.110 --> 00:08:22.060\n Dexter Horthy: And then we're putting the user. The question in the user prompt.\n \n 62\n 00:08:23.070 --> 00:08:23.960\n Vaibhav Gupta: Exactly.\n \n 63\n 00:08:24.190 --> 00:08:27.299\n Vaibhav Gupta: So I'm gonna do this. So now there's my prompt\n \n 64\n 00:08:28.690 --> 00:08:37.279\n Vaibhav Gupta: and I will literally just ask her sort of generate me a test case for this rag use case\n \n 65\n 00:08:37.860 --> 00:08:42.610\n Vaibhav Gupta: use resume.\n \n 66\n 00:08:46.090 --> 00:08:49.600\n Dexter Horthy: They are all the same file. They're all gonna have a test case in them.\n \n 67\n 00:08:49.820 --> 00:08:58.780\n Vaibhav Gupta: I'm gonna move this username as as a reference for how that all works.\n \n 68\n 00:08:59.420 --> 00:09:01.580\n Vaibhav Gupta: So I'll just have to generate a test case really fast.\n \n 69\n 00:09:02.310 --> 00:09:13.099\n Vaibhav Gupta: and then it'll just go do something for me, but we can see how like and then this takes a little bit, but we can see how like the model might struggle to go. Do something great except\n \n 70\n 00:09:13.250 --> 00:09:14.040\n Vaibhav Gupta: cool.\n \n 71\n 00:09:14.820 --> 00:09:16.236\n Vaibhav Gupta: Let's go do this.\n \n 72\n 00:09:16.590 --> 00:09:20.527\n Dexter Horthy: Oh, man, are you gonna make these urls really freaking crazy? And then,\n \n 73\n 00:09:20.970 --> 00:09:23.029\n Dexter Horthy: see if we can actually get the model to screw it up.\n \n 74\n 00:09:23.560 --> 00:09:24.619\n Vaibhav Gupta: Use this.\n \n 75\n 00:09:26.130 --> 00:09:28.230\n Vaibhav Gupta: So this is one Youtube, URL\n \n 76\n 00:09:28.980 --> 00:09:32.369\n Vaibhav Gupta: and I will copy another Youtube URL from a different video.\n \n 77\n 00:09:36.700 --> 00:09:44.820\n Vaibhav Gupta: And I will point this out. It's not even a matter of like the model will screw this up. The point here is, it doesn't matter if the model does this perfectly or not\n \n 78\n 00:09:44.990 --> 00:09:49.429\n Vaibhav Gupta: the point that matters is, the model might screw it up.\n \n 79\n 00:09:50.240 --> 00:10:03.049\n Vaibhav Gupta: and if it screws it up I have no guarantee on this end. So there's small things that I can do. So. Now that I have some citation thing in here, I can do something nice in my python code to help reduce some of these errors.\n \n 80\n 00:10:04.950 --> 00:10:13.590\n Dexter Horthy: Oh, you can put like a guard. This is from the Eval saying, you put a runtime guard of like, hey? If it outputs a URL that wasn't in our input set, bounce it back and tell it to try again.\n \n 81\n 00:10:13.590 --> 00:10:17.017\n Vaibhav Gupta: Let me actually open just this one folder really fast\n \n 82\n 00:10:18.680 --> 00:10:20.469\n Vaibhav Gupta: that way. It's only a little bit cleaner.\n \n 83\n 00:10:21.100 --> 00:10:21.900\n Vaibhav Gupta: There you go.\n \n 84\n 00:10:22.660 --> 00:10:28.100\n Vaibhav Gupta: Otherwise Python versions don't work for Monorepos, which is the worst thing that Python is committed.\n \n 85\n 00:10:28.650 --> 00:10:33.919\n Dexter Horthy: We're getting there. I think the UV dot python stuff might actually eventually fix it.\n \n 86\n 00:10:34.690 --> 00:10:36.310\n Vaibhav Gupta: I really hope so.\n \n 87\n 00:10:39.700 --> 00:10:42.840\n Vaibhav Gupta: So. One thing I can do is I can literally just get the answer\n \n 88\n 00:10:43.240 --> 00:10:49.025\n Vaibhav Gupta: equals this, and then I can say like for URL in answer\n \n 89\n 00:10:49.770 --> 00:11:00.709\n Vaibhav Gupta: answer, dot citations. I somehow assert that the URL starts with this. I could like build some small search. I could, I could assert that the Urls are actually natural. Content array that comes in there.\n \n 90\n 00:11:05.070 --> 00:11:05.910\n Vaibhav Gupta: Oh.\n \n 91\n 00:11:07.770 --> 00:11:09.730\n Dexter Horthy: I got it I'll I'll get the link.\n \n 92\n 00:11:10.898 --> 00:11:21.090\n Vaibhav Gupta: So we can actually go build this URL right for us. Now, we can actually go further. The problem is right over here. This Urls, as we saw, have a problem with how the models to generate them.\n \n 93\n 00:11:22.240 --> 00:11:27.140\n Vaibhav Gupta: So let's go fix that actually. And let's say, this is our actual Urls.\n \n 94\n 00:11:30.820 --> 00:11:39.720\n Vaibhav Gupta: Oh, from Bamo, client dot types import content.\n \n 95\n 00:11:40.580 --> 00:11:49.239\n Vaibhav Gupta: Now, what I can do here is, instead of actually putting this URL, as is, I could literally put a I could 1st change this completely\n \n 96\n 00:11:49.620 --> 00:11:55.599\n Vaibhav Gupta: and say, what I actually want to do is I won't list a return of citation. I will actually list an index\n \n 97\n 00:11:56.990 --> 00:11:59.830\n Vaibhav Gupta: index of the content.\n \n 98\n 00:12:01.670 --> 00:12:07.130\n Vaibhav Gupta: And now that this returns an index of the content, what I will do here is literally just print this out content\n \n 99\n 00:12:09.010 --> 00:12:15.229\n Vaibhav Gupta: loop dot index 0 content idx. And now my prompt looks like this.\n \n 100\n 00:12:15.700 --> 00:12:24.979\n Vaibhav Gupta: instead of actually dumping the actual URL, I just say, content. Idx 0, 0. I can actually put like dashes here, separators. I can put them beforehand, because that might actually be better\n \n 101\n 00:12:27.510 --> 00:12:28.730\n Vaibhav Gupta: content.\n \n 102\n 00:12:29.670 --> 00:12:41.700\n Vaibhav Gupta: I can do this and now it's actually called content out content, one content. 0. And now I just remove the idea of the URL completely from the model, and the model will not do this, and when I go run this.\n \n 103\n 00:12:43.330 --> 00:12:49.019\n Vaibhav Gupta: what we'll find is great. We get 0 and one because those are relevant indexes. And like, let's make up a 3rd one. That doesn't matter.\n \n 104\n 00:12:52.810 --> 00:12:59.660\n Vaibhav Gupta: Europe is pretty cool and has great pasta.\n \n 105\n 00:13:01.580 --> 00:13:09.350\n Vaibhav Gupta: and ideally, it shouldn't pick up the right content. It should only pick up 0 and one. And now what I can do in my code, instead of doing it in the model is, I can convert\n \n 106\n 00:13:09.550 --> 00:13:13.509\n Vaibhav Gupta: the URL into the actual citation.\n \n 107\n 00:13:13.620 --> 00:13:15.199\n Vaibhav Gupta: So now I can just say, like\n \n 108\n 00:13:15.410 --> 00:13:18.870\n Vaibhav Gupta: content of URL Dot, what is it\n \n 109\n 00:13:19.430 --> 00:13:30.320\n Vaibhav Gupta: content of URL dot URL, or the actual URL that I actually want? So it becomes an index based lookup instead of a real one. So the idea is, you really don't you really want to do your best.\n \n 110\n 00:13:30.820 --> 00:13:35.549\n Vaibhav Gupta: and to not rely on models generating long sequences of tokens\n \n 111\n 00:13:35.680 --> 00:13:40.349\n Vaibhav Gupta: that don't make sense for the model to actually, intuitively think about similar.\n \n 112\n 00:13:40.350 --> 00:13:45.370\n Dexter Horthy: No meaning. There's no meaning baked into that random string of characters. It's just a pointer.\n \n 113\n 00:13:45.640 --> 00:13:57.050\n Vaibhav Gupta: Exactly. And if you can go further, and if you go back to our content about dynamic enums, you could, for example, make this a dynamic enum that then has an alias that gets mapped back to the actual file.\n \n 114\n 00:13:57.050 --> 00:14:07.779\n Dexter Horthy: Yeah, I was. Gonna say, we could go into all of the fancy bamel features that make this even easier. I am. Gonna say we are 20 min in. So if you, if you want to move on to the next tip, or do you want to wrap this one up or or do you have more\n \n 115\n 00:14:08.440 --> 00:14:09.110\n Dexter Horthy: stuff?\n \n 116\n 00:14:09.280 --> 00:14:10.320\n Dexter Horthy: Perfect.\n \n 117\n 00:14:10.320 --> 00:14:15.459\n Vaibhav Gupta: It's don't use sequences of tokens that don't make sense for the model. Go update it on your own.\n \n 118\n 00:14:15.880 --> 00:14:20.020\n Dexter Horthy: We got one question. Symbol tuning also applies here.\n \n 119\n 00:14:20.020 --> 00:14:26.520\n Vaibhav Gupta: Exactly. Symbol tuning is exact. Same thing. Docs will cover that. Can't talk about that right now because of time constraints.\n \n 120\n 00:14:26.920 --> 00:14:29.010\n Vaibhav Gupta: We're gonna do another one diarization.\n \n 121\n 00:14:29.440 --> 00:14:39.260\n Vaibhav Gupta: So we've all seen diarization examples. We're like, do this make a make a transcript do diarization\n \n 122\n 00:14:39.890 --> 00:14:49.639\n Vaibhav Gupta: diarization function, use labels of ammo as an example.\n \n 123\n 00:14:50.490 --> 00:14:55.030\n Dexter Horthy: Do you want to do a quick whiteboard on like? What? What do we mean by diarization?\n \n 124\n 00:14:55.798 --> 00:14:59.480\n Vaibhav Gupta: Will go do this. I'll describe some words over here.\n \n 125\n 00:15:00.210 --> 00:15:02.040\n Dexter Horthy: So let's talk about diarization.\n \n 126\n 00:15:02.530 --> 00:15:13.470\n Vaibhav Gupta: Diarization. Diarization. Diarization is this idea that we have audio coming in and we want to turn the audio snippets into like a\n \n 127\n 00:15:13.670 --> 00:15:21.859\n Vaibhav Gupta: speaker plus transcript section. So each of these will always have a speaker, and each of these will, and then transform into like, who said, What\n \n 128\n 00:15:22.020 --> 00:15:25.099\n Vaibhav Gupta: so idea is, most of these sequences come from.\n \n 129\n 00:15:26.166 --> 00:15:33.579\n Vaibhav Gupta: And Mo, what most of these will do is they'll basically say, literally, say, Speaker, 0 speaker, one speaker, 0 speaker, one\n \n 130\n 00:15:34.657 --> 00:15:47.990\n Vaibhav Gupta: and you might actually want to go do something more than that, because you might be having a conversation between a nurse and a patient. So you might actually want to say, speaker, one is a nurse speaker 2 is a patient and transform your transcript to that.\n \n 131\n 00:15:48.400 --> 00:15:53.284\n Vaibhav Gupta: I'm going to show you a prompting trip that is going to reduce the amount of\n \n 132\n 00:15:53.860 --> 00:16:01.219\n Vaibhav Gupta: text that we might have to generate by an order of magnitude to solve this problem. Because if I want to go from person one\n \n 133\n 00:16:01.460 --> 00:16:08.660\n Vaibhav Gupta: to speaker like nurse versus patient\n \n 134\n 00:16:12.280 --> 00:16:14.570\n Vaibhav Gupta: versus like\n \n 135\n 00:16:14.800 --> 00:16:21.400\n Vaibhav Gupta: other, because maybe their husband or wife spoke up into it in the middle of it. I want to know exactly who these personas are.\n \n 136\n 00:16:21.740 --> 00:16:24.010\n Vaibhav Gupta: So let's go do that, and.\n \n 137\n 00:16:24.010 --> 00:16:34.920\n Dexter Horthy: Real real quick is, there is, does it? Is? I imagine this is probably equivalent whether you're doing audio or raw, just like a raw transcript of a conversation right.\n \n 138\n 00:16:35.470 --> 00:16:45.739\n Vaibhav Gupta: Yes, so I'm gonna assume that the transcript is, gonna have a speaker. Let's just say the transcript is on. Let's simplify this a little bit. Let's say the transcript is literally just a string.\n \n 139\n 00:16:47.250 --> 00:16:51.189\n Vaibhav Gupta: and what I want to do is I want to identify the speakers that exist for each of these\n \n 140\n 00:16:51.660 --> 00:16:54.959\n Vaibhav Gupta: right? So the transcript is literally just going to be a string.\n \n 141\n 00:16:55.340 --> 00:16:58.949\n Vaibhav Gupta: And I I have no other information about it.\n \n 142\n 00:17:00.801 --> 00:17:07.980\n Vaibhav Gupta: Transcript will turn into that, and then what I want is I want to return a diarized transcript which is going to be a bunch of speaker. Segments don't need this.\n \n 143\n 00:17:08.510 --> 00:17:15.630\n Vaibhav Gupta: and this will just have Speaker string text. And you might even say that this is like nurse.\n \n 144\n 00:17:16.650 --> 00:17:18.969\n Vaibhav Gupta: doctor, patient or other.\n \n 145\n 00:17:19.550 --> 00:17:21.790\n Vaibhav Gupta: So let's let's like right here.\n \n 146\n 00:17:22.359 --> 00:17:22.969\n Dexter Horthy: Cool.\n \n 147\n 00:17:26.189 --> 00:17:29.119\n Vaibhav Gupta: Identify, identify the speakers.\n \n 148\n 00:17:30.719 --> 00:17:34.629\n Vaibhav Gupta: Ctx dot output format.\n \n 149\n 00:17:36.229 --> 00:17:42.899\n Vaibhav Gupta: And then user, okay, cool. That's probably good enough.\n \n 150\n 00:17:43.359 --> 00:17:44.959\n Vaibhav Gupta: Oh, that's actually pretty cool.\n \n 151\n 00:17:48.029 --> 00:17:48.769\n Vaibhav Gupta: Let's change.\n \n 152\n 00:17:48.770 --> 00:17:50.960\n Dexter Horthy: But you actually just want the raw text, right?\n \n 153\n 00:17:51.230 --> 00:17:55.009\n Vaibhav Gupta: Yeah, so I will. Oh, yeah, that's true. Thank you for identifying that, Dexter.\n \n 154\n 00:17:55.867 --> 00:17:59.190\n Vaibhav Gupta: Actually, I think, test cases converted correctly.\n \n 155\n 00:18:08.640 --> 00:18:09.920\n Vaibhav Gupta: how are you?\n \n 156\n 00:18:10.300 --> 00:18:15.110\n Vaibhav Gupta: I'm hurt my knee hearts.\n \n 157\n 00:18:16.000 --> 00:18:17.170\n Vaibhav Gupta: I'm sorry.\n \n 158\n 00:18:18.300 --> 00:18:25.119\n Dexter Horthy: Sorry. So so this is already. Has the speakers identified, though right like.\n \n 159\n 00:18:25.120 --> 00:18:27.130\n Vaibhav Gupta: But it doesn't tell me who's who.\n \n 160\n 00:18:29.130 --> 00:18:36.559\n Dexter Horthy: Okay is, so would this technique work like, is this applicable also to just a\n \n 161\n 00:18:36.730 --> 00:18:43.680\n Dexter Horthy: like non, like, if I just have a a stream of text, and I don't. It's not already split up by speaker.\n \n 162\n 00:18:44.870 --> 00:18:45.529\n Dexter Horthy: I guess.\n \n 163\n 00:18:45.940 --> 00:18:50.551\n Dexter Horthy: Okay, so this just assumes you have turn detection, but not necessarily\n \n 164\n 00:18:51.320 --> 00:18:57.620\n Vaibhav Gupta: Let's say we don't know the speaker. We don't know anything about this. What we really want to do is we want to go and convert this in a really quick way.\n \n 165\n 00:18:58.529 --> 00:19:15.780\n Vaibhav Gupta: So I'm gonna go change it. It's been hurting for 3 days now fix. He's been complaining about it for a while. So this is interesting because there might be a lot of other content here. So let's just see, firstly, what the what, the what the raw thing ends up being.\n \n 166\n 00:19:17.020 --> 00:19:19.500\n Dexter Horthy: Yeah, cool. This.\n \n 167\n 00:19:19.710 --> 00:19:24.669\n Vaibhav Gupta: This seems kind of interesting. It's like cool. It has other. It has all these other things in here.\n \n 168\n 00:19:24.900 --> 00:19:27.590\n Vaibhav Gupta: Let's try and make this better really fast.\n \n 169\n 00:19:28.757 --> 00:19:44.199\n Vaibhav Gupta: And I'm gonna combine like 2 or 3 different of the prompting tips right in one as I go. So the 1st thing I'm gonna notice is, Hey, this is probably not very useful. So let's try and just like fix this.\n \n 170\n 00:19:44.200 --> 00:19:45.840\n Dexter Horthy: What part of it is not useful.\n \n 171\n 00:19:45.840 --> 00:19:48.739\n Vaibhav Gupta: Well, one, I'm outputting the whole transcript over and over again.\n \n 172\n 00:19:49.470 --> 00:19:50.579\n Vaibhav Gupta: That sounds bad.\n \n 173\n 00:19:51.140 --> 00:19:53.690\n Vaibhav Gupta: Let's see if we can do this in a slightly better way.\n \n 174\n 00:19:54.363 --> 00:20:01.020\n Vaibhav Gupta: So what I'm going to do is I'm gonna say, dialogue index.\n \n 175\n 00:20:01.240 --> 00:20:01.950\n Vaibhav Gupta: And\n \n 176\n 00:20:02.670 --> 00:20:08.269\n Vaibhav Gupta: so I'm gonna give it. Give it the dialog index. And here I'm just gonna like, write this in my prompt, really fast.\n \n 177\n 00:20:08.930 --> 00:20:12.017\n Vaibhav Gupta: So I don't have to think about this. But\n \n 178\n 00:20:12.760 --> 00:20:14.409\n Vaibhav Gupta: the right way to do this is\n \n 179\n 00:20:14.860 --> 00:20:17.040\n Vaibhav Gupta: honestly to just make this thing an array.\n \n 180\n 00:20:20.534 --> 00:20:21.049\n Vaibhav Gupta: Sorry\n \n 181\n 00:20:28.500 --> 00:20:31.560\n Vaibhav Gupta: I love cursor, and we'll make this an array.\n \n 182\n 00:20:31.920 --> 00:20:38.860\n Vaibhav Gupta: And now, instead of dumping the Transcript out as we are what we'll do as well as a or a line and transcript printed the line.\n \n 183\n 00:20:39.300 --> 00:20:44.670\n Vaibhav Gupta: And now what we'll also say is this loop dot index 0 dialogue.\n \n 184\n 00:20:47.060 --> 00:20:50.769\n Vaibhav Gupta: This add an extra space in there and then we'll add that in.\n \n 185\n 00:20:51.210 --> 00:20:53.220\n Vaibhav Gupta: So now what we'll.\n \n 186\n 00:20:53.220 --> 00:21:02.830\n sahil: An assumption that the the script is already an array, or are we just converting the script into an array like.\n \n 187\n 00:21:03.110 --> 00:21:09.939\n Vaibhav Gupta: You can just split by you can just split by. I'm assuming, if you have some way of a speaker, Colon. Here, you have a way to convert this into an array of some kind.\n \n 188\n 00:21:10.440 --> 00:21:11.150\n sahil: Okay.\n \n 189\n 00:21:11.430 --> 00:21:25.990\n Dexter Horthy: Yeah, I think I think in, yeah, I think the questions that a lot of people are asking is kind of the like, the real time, actual speech to text use cases. You don't have those like separators unless you're using like a separate like, turn detection model, basically.\n \n 190\n 00:21:26.270 --> 00:21:40.230\n Vaibhav Gupta: Yes, but most people should be using a turn detection model. So I'm assuming that you have that right now, you're analyzing a transcript in post. We can remove the speaker labels as well. So it's like a little bit more clear. It's like we just have all the statements that are literally speech to text per line of some kind.\n \n 191\n 00:21:40.560 --> 00:21:42.090\n Vaibhav Gupta: I'm gonna go run this now.\n \n 192\n 00:21:42.310 --> 00:21:43.750\n Vaibhav Gupta: Now you'll notice\n \n 193\n 00:21:44.030 --> 00:21:50.570\n Vaibhav Gupta: the model is actually really, really good at just bidding out the dialogue index, and who the who the speaker is. In each of these scenarios.\n \n 194\n 00:21:51.160 --> 00:21:54.129\n Dexter Horthy: Oh, so it doesn't have to re output the actual text itself.\n \n 195\n 00:21:54.130 --> 00:22:01.560\n Vaibhav Gupta: Exactly order of magnet you can imagine for long transcripts. This is an order of magnitude cheaper\n \n 196\n 00:22:01.870 --> 00:22:07.480\n Vaibhav Gupta: in terms of how much text that's output, and we can reduce this even further and just like aliases to like\n \n 197\n 00:22:07.910 --> 00:22:10.120\n Vaibhav Gupta: alias idx.\n \n 198\n 00:22:11.300 --> 00:22:15.779\n Vaibhav Gupta: And then it'll be a lot shorter. And now it's just now it's just outputting the index, and the speaker.\n \n 199\n 00:22:17.060 --> 00:22:17.420\n Dexter Horthy: I'm.\n \n 200\n 00:22:17.420 --> 00:22:18.020\n Vaibhav Gupta: And.\n \n 201\n 00:22:18.020 --> 00:22:21.630\n Dexter Horthy: A little curious what would happen if you just put it all as one big string.\n \n 202\n 00:22:22.310 --> 00:22:23.859\n Vaibhav Gupta: What do you mean? Oh.\n \n 203\n 00:22:23.860 --> 00:22:28.610\n Dexter Horthy: Like like, if you didn't split them out. I imagine it's probably not gonna work as well, but.\n \n 204\n 00:22:28.930 --> 00:22:42.880\n Vaibhav Gupta: The reason that this works a lot better is twofold one. I'm actually telling it the model what the index is. So the model has to go back and say, Let's look at what the model does turn by turn. It's going to 1st output idx 0,\n \n 205\n 00:22:43.190 --> 00:23:05.820\n Vaibhav Gupta: then all it has to do is in its token. During the attention mechanism the model goes back into its tokenizer, so it literally will go back through all the tokens and just say, Okay, what tokens I want to look at. I want to look at next 0. It's going to go in to say, Okay, I need to understand this part of this part of the segment, it's easier for it to focus. So even though it's a little redundant, it helps the model be a little bit more focused\n \n 206\n 00:23:06.080 --> 00:23:09.710\n Vaibhav Gupta: on its part. Now it's like, Okay, what? Who likely? Said this?\n \n 207\n 00:23:10.540 --> 00:23:26.409\n Vaibhav Gupta: And then it's like, and then it goes out and starts spitting out the next token spits out idx. So at the point of idx, now it says, Oh, what's the next idx I need? Oh, let me go back a couple tokens here is like that was 0. I probably need one. Next, we're reducing the burden on the model.\n \n 208\n 00:23:26.690 --> 00:23:30.190\n Vaibhav Gupta: That's the main. That's the main leverage here.\n \n 209\n 00:23:30.460 --> 00:23:36.670\n Vaibhav Gupta: The model at any point is able to do way less work, and then therefore output more. Does that make sense Dexter.\n \n 210\n 00:23:37.350 --> 00:23:38.699\n Dexter Horthy: Yeah, I got you cool.\n \n 211\n 00:23:39.060 --> 00:23:39.750\n Vaibhav Gupta: Cool.\n \n 212\n 00:23:40.290 --> 00:23:49.089\n Vaibhav Gupta: Now the thing is, we may not actually know exactly who's talking here like this other thing. We might have made a bug and not actually introduced other.\n \n 213\n 00:23:50.160 --> 00:23:54.710\n Vaibhav Gupta: And in this scenario what we'll find is likely the model.\n \n 214\n 00:23:55.790 --> 00:23:57.820\n Vaibhav Gupta: We'll do something just output. It's a nurse.\n \n 215\n 00:23:58.050 --> 00:24:00.389\n Vaibhav Gupta: it kind of hallucinated on its own.\n \n 216\n 00:24:01.010 --> 00:24:03.249\n Vaibhav Gupta: So we can actually just add other\n \n 217\n 00:24:03.780 --> 00:24:11.399\n Vaibhav Gupta: as a fallback. So we, the model doesn't tend to hallucinate. We want to prevent hallucinations when possible, and we do that by giving the model and out. That's the.\n \n 218\n 00:24:11.400 --> 00:24:33.350\n Dexter Horthy: And this is the same with all the all, the classifier examples that that we talk about. Right is like, classify the things you know you are good at classifying in the fastest, cheapest, most efficient way, and then allow the model to have an escape hatch, in which case you'll handle it in a different way, either by sending it to a human to classify or sending it to a bigger, smarter model, or whatever it is.\n \n 219\n 00:24:33.650 --> 00:24:40.320\n Vaibhav Gupta: Exactly. But now let's do another thing. Let's do another thing, clues, but that's some clues here.\n \n 220\n 00:24:40.560 --> 00:24:41.280\n Vaibhav Gupta: So I'm gonna.\n \n 221\n 00:24:41.280 --> 00:24:41.720\n Dexter Horthy: Reasoning.\n \n 222\n 00:24:41.720 --> 00:24:46.840\n Vaibhav Gupta: Things that I'm exactly. So I'm gonna help the model think about what it is. And it's literally just like\n \n 223\n 00:24:47.760 --> 00:24:50.190\n Vaibhav Gupta: it's literally just dumping the text here.\n \n 224\n 00:24:52.141 --> 00:24:59.110\n Vaibhav Gupta: And like this is not very useful. Add description, things that help inference.\n \n 225\n 00:24:59.430 --> 00:25:00.530\n Vaibhav Gupta: To.\n \n 226\n 00:25:01.310 --> 00:25:04.399\n Vaibhav Gupta: Let's just add a little bit more dialogue here, and we'll see what it does.\n \n 227\n 00:25:08.695 --> 00:25:13.750\n Vaibhav Gupta: let's say what might\n \n 228\n 00:25:14.982 --> 00:25:26.379\n Vaibhav Gupta: relevant. So let's so we're noticing that what it's doing is just outputting all the clues, but a lot of the times. It's kind of obvious who the speaker is. So let's just do this only, if not obvious.\n \n 229\n 00:25:28.717 --> 00:25:33.560\n Vaibhav Gupta: List out facts that help us.\n \n 230\n 00:25:35.250 --> 00:25:38.090\n Vaibhav Gupta: Identify, help us, analyze.\n \n 231\n 00:25:38.500 --> 00:25:47.359\n Dexter Horthy: Yeah. John's suggesting deductive reasoning steps, which I think is gets a little towards some of the stuff we've done in the past around like structured reasoning stuff.\n \n 232\n 00:25:47.670 --> 00:25:52.440\n Vaibhav Gupta: There who the speaker may be.\n \n 233\n 00:25:52.980 --> 00:25:55.470\n Vaibhav Gupta: I had a much better test case pulled up earlier.\n \n 234\n 00:25:56.270 --> 00:25:58.649\n Vaibhav Gupta: So and now you're noticing over here.\n \n 235\n 00:25:59.600 --> 00:26:00.020\n Dexter Horthy: Hmm.\n \n 236\n 00:26:00.020 --> 00:26:02.330\n Vaibhav Gupta: Now something a lot more interesting.\n \n 237\n 00:26:03.040 --> 00:26:10.769\n Vaibhav Gupta: It says Speaker 0 other because they don't know yet. Speaker, one uses personal pronouns indicating injury. That means that they're probably a patient\n \n 238\n 00:26:11.430 --> 00:26:16.580\n Vaibhav Gupta: speaking about the patient, so probably other along the way.\n \n 239\n 00:26:18.460 --> 00:26:25.099\n Vaibhav Gupta: So it's actually a lot more useful to actually go do this. And now we can have a lot more comp confidence behind what's happening.\n \n 240\n 00:26:25.960 --> 00:26:30.609\n Dexter Horthy: But it's also it's it's gotten. It's it's gotten worse at picking the ones where it was. The.\n \n 241\n 00:26:30.610 --> 00:26:33.159\n Prashanth Rao: The doctor, the doctor and nurse are worse.\n \n 242\n 00:26:33.650 --> 00:26:35.089\n Vaibhav Gupta: Yes, but\n \n 243\n 00:26:35.690 --> 00:26:45.479\n Vaibhav Gupta: that might be because when you really think about it, doctor and nurse are actually confusing, because how does it actually identify correctly between the doctor and the nurse.\n \n 244\n 00:26:46.720 --> 00:26:48.650\n Vaibhav Gupta: and we can go about this one more time.\n \n 245\n 00:26:48.910 --> 00:26:50.690\n Vaibhav Gupta: And if we actually go, look at this.\n \n 246\n 00:26:50.910 --> 00:26:58.770\n Vaibhav Gupta: If I were to read this transcript. There is no freaking way. I, as a human, would actually be able to know if it's actually a doctor or a patient doctor or not\n \n 247\n 00:27:00.160 --> 00:27:02.420\n Vaibhav Gupta: without knowing how many people are in the room.\n \n 248\n 00:27:03.880 --> 00:27:04.840\n Prashanth Rao: Very true.\n \n 249\n 00:27:05.150 --> 00:27:07.520\n Vaibhav Gupta: I could be talking to my brother.\n \n 250\n 00:27:07.520 --> 00:27:09.780\n Vaibhav Gupta: Exactly, exactly, and that's the.\n \n 251\n 00:27:09.780 --> 00:27:11.610\n Dexter Horthy: Could be my uncle talking shit.\n \n 252\n 00:27:12.360 --> 00:27:22.729\n Vaibhav Gupta: So whenever some, when you said doctor and patient got nurse, you're right. We intuitively felt that way. But remember, the model has no context around this. So let's add some more context.\n \n 253\n 00:27:22.730 --> 00:27:26.790\n Prashanth Rao: Sorry could you go to? So before you clear this out, could you go to the 3rd index? Index? Number 2?\n \n 254\n 00:27:27.900 --> 00:27:30.919\n Prashanth Rao: Yeah, this this time it seems to have gotten it.\n \n 255\n 00:27:31.350 --> 00:27:33.280\n Vaibhav Gupta: Because it's making assumptions.\n \n 256\n 00:27:33.420 --> 00:27:34.319\n Prashanth Rao: Yeah, yeah.\n \n 257\n 00:27:34.320 --> 00:27:36.779\n Vaibhav Gupta: About it right? It's made. But now we.\n \n 258\n 00:27:36.780 --> 00:27:41.590\n Dexter Horthy: Taking more from the prompt itself, like the actual output format, right.\n \n 259\n 00:27:41.590 --> 00:27:48.639\n Vaibhav Gupta: Exactly. It's literally just like, you're probably either doctor or patient, like there's no there's no way around this. But now that we force the model to be like\n \n 260\n 00:27:49.250 --> 00:27:53.159\n Vaibhav Gupta: who, if not only if not obvious, go list out facts.\n \n 261\n 00:27:54.040 --> 00:27:59.940\n Vaibhav Gupta: And in fact, the obvious answer for identifying speakers may be other in all scenarios.\n \n 262\n 00:28:00.970 --> 00:28:06.550\n Vaibhav Gupta: and that's what I would do if I had, I would unlabel everything. But then I would say, Oh.\n \n 263\n 00:28:07.200 --> 00:28:13.100\n Vaibhav Gupta: but now we know for sure that this one is a patient because it has been non obviously stated.\n \n 264\n 00:28:13.840 --> 00:28:16.850\n Vaibhav Gupta: But we can go further. We can make this a little bit better.\n \n 265\n 00:28:18.600 --> 00:28:47.060\n Vaibhav Gupta: There there were 4 people in the room, Dr. Josh, there's 5 h next, the friend unidentified.\n \n 266\n 00:28:48.460 --> 00:28:52.599\n Vaibhav Gupta: So we can go do this cause, maybe, for my Emr. I know exactly who visited.\n \n 267\n 00:28:53.240 --> 00:28:56.819\n Vaibhav Gupta: but I don't know. I don't have any information on the other person at all.\n \n 268\n 00:28:57.660 --> 00:29:04.820\n Vaibhav Gupta: So now let's add this in here and say for context.\n \n 269\n 00:29:12.300 --> 00:29:14.219\n Vaibhav Gupta: And now let's let's run this.\n \n 270\n 00:29:16.850 --> 00:29:20.260\n Vaibhav Gupta: And now what we find is that the model gets a lot better.\n \n 271\n 00:29:21.760 --> 00:29:36.690\n Dexter Horthy: Right? So you could. You could look at like, if you want to do this for a random event, you could go get the people off the Google Calendar event, and just inject that at the top, like, here's the people. And here's their domains. And here's, you know, 2 sentences of deep research about who this person is.\n \n 272\n 00:29:37.100 --> 00:29:53.039\n Vaibhav Gupta: Exactly. And this, this mechanism of how we felt like it got more inaccurate, and might have diverted us from actually exploring this prompt further is actually important to understand why the model did this step back, rethink and remember that the model did this? Because\n \n 273\n 00:29:53.230 --> 00:30:10.189\n Vaibhav Gupta: if I were to be completely objective. Show this to a random person to have tell them identify speakers. They also would likely pick other if they have to be like, if the choice would be wrong or be correct. I, too, would prefer to be not wrong, and just pick other, because other is never wrong.\n \n 274\n 00:30:11.640 --> 00:30:12.390\n Dexter Horthy: Cool.\n \n 275\n 00:30:13.870 --> 00:30:15.880\n Dexter Horthy: Are we gonna trip back? Takes today?\n \n 276\n 00:30:16.120 --> 00:30:20.489\n Vaibhav Gupta: I'll do that in a second. That's Tip number 2, where we use diarization.\n \n 277\n 00:30:20.610 --> 00:30:26.190\n Vaibhav Gupta: And I want to show one last variant of this trick. Which is these clues.\n \n 278\n 00:30:27.120 --> 00:30:39.480\n Vaibhav Gupta: So instead of outputting clues, we can just do this description as a precursor to the comment.\n \n 279\n 00:30:40.090 --> 00:30:45.945\n Vaibhav Gupta: as a precursor sort of comment to this field.\n \n 280\n 00:30:46.800 --> 00:30:47.970\n Vaibhav Gupta: So sometimes we want.\n \n 281\n 00:30:47.970 --> 00:30:48.500\n Dexter Horthy: Shit.\n \n 282\n 00:30:49.940 --> 00:30:55.999\n Vaibhav Gupta: But we don't want it to do reasoning as a data field. I don't want to deal with that. I just wanted to like output something.\n \n 283\n 00:30:56.700 --> 00:30:58.800\n Vaibhav Gupta: and I want to show you what happens here.\n \n 284\n 00:31:00.470 --> 00:31:06.900\n Vaibhav Gupta: If this works exam.\n \n 285\n 00:31:06.900 --> 00:31:18.719\n Dexter Horthy: Okay, so this is getting into like, how do we? How do we? This is a great leeway. This is like, how do we get the model to output busted Json in a way that like actually helps it get better. Answers.\n \n 286\n 00:31:23.560 --> 00:31:26.740\n Dexter Horthy: like comments in Json are technically not valid.\n \n 287\n 00:31:28.270 --> 00:31:31.879\n Vaibhav Gupta: Let's see if I can force it to do this. I have to actually read the prompt and see what it's doing\n \n 288\n 00:31:36.020 --> 00:31:37.210\n Vaibhav Gupta: views.\n \n 289\n 00:31:40.110 --> 00:31:41.240\n Dexter Horthy: As.\n \n 290\n 00:31:42.370 --> 00:32:11.450\n Vaibhav Gupta: If if not, if speaker is ambiguous, list relevant comments the help, narrow help a narrow down toggle\n \n 291\n 00:32:12.700 --> 00:32:14.572\n Vaibhav Gupta: to help narrow down.\n \n 292\n 00:32:15.600 --> 00:32:16.860\n Vaibhav Gupta: No speaker\n \n 293\n 00:32:25.890 --> 00:32:27.320\n Vaibhav Gupta: use 1st\n \n 294\n 00:32:31.240 --> 00:32:31.910\n Vaibhav Gupta: cool.\n \n 295\n 00:32:34.940 --> 00:32:37.180\n Vaibhav Gupta: and we'll go run this and see what the model does.\n \n 296\n 00:32:38.130 --> 00:32:41.199\n Vaibhav Gupta: Okay, I can't get to do it. Let me try and put this out.\n \n 297\n 00:32:44.860 --> 00:32:47.659\n Vaibhav Gupta: This is like the weirdest trick that I've learned, and.\n \n 298\n 00:32:56.490 --> 00:33:00.680\n Dexter Horthy: So, not directly in the generated output format, but just in the prompt.\n \n 299\n 00:33:01.820 --> 00:33:03.130\n Vaibhav Gupta: And the XM.\n \n 300\n 00:33:04.100 --> 00:33:12.450\n Vaibhav Gupta: Use fresh and had, and excellent.\n \n 301\n 00:33:14.120 --> 00:33:14.790\n Dexter Horthy: Okay.\n \n 302\n 00:33:15.000 --> 00:33:18.040\n Dexter Horthy: So you always tell me not to use a few shot prompting.\n \n 303\n 00:33:18.690 --> 00:33:19.600\n Vaibhav Gupta: I do?\n \n 304\n 00:33:21.250 --> 00:33:29.120\n Dexter Horthy: Because this is more about the structure of the response, not about the actual, like learning from examples, basically.\n \n 305\n 00:33:29.120 --> 00:33:30.120\n Vaibhav Gupta: Exactly.\n \n 306\n 00:33:30.610 --> 00:33:35.510\n Vaibhav Gupta: So let's see if I can get the model to output this. And sometimes I can't. Sometimes the model doesn't really listen\n \n 307\n 00:33:36.027 --> 00:33:44.330\n Vaibhav Gupta: and just dump that info as another field. So let's do another last thing prefix equals answer. With\n \n 308\n 00:33:44.630 --> 00:33:48.409\n Vaibhav Gupta: this I noticed Openai has been doing this.\n \n 309\n 00:33:49.250 --> 00:33:58.119\n Vaibhav Gupta: Oh, where like, I think, for whatever reason, whenever you use the word Json, they trigger something special in the prompt that goes to like some other model or something.\n \n 310\n 00:33:58.120 --> 00:34:01.390\n Dexter Horthy: So, or like secretly turns on.\n \n 311\n 00:34:01.390 --> 00:34:03.859\n Vaibhav Gupta: There you go. Yes, exactly.\n \n 312\n 00:34:06.110 --> 00:34:08.535\n Vaibhav Gupta: And now the models actually\n \n 313\n 00:34:09.874 --> 00:34:13.775\n Vaibhav Gupta: writing some more comments. But it's right in the comments after\n \n 314\n 00:34:14.320 --> 00:34:21.739\n Vaibhav Gupta: If list relevant facts helping out on Speaker before the speaker fields see you but be a little.\n \n 315\n 00:34:21.739 --> 00:34:23.969\n Dexter Horthy: Reasoning before the output.\n \n 316\n 00:34:24.159 --> 00:34:24.729\n Vaibhav Gupta: Yeah.\n \n 317\n 00:34:26.265 --> 00:34:33.150\n sahil: Question. So the reason to do this is to save the tokens on item clue. Every single.\n \n 318\n 00:34:33.159 --> 00:34:33.689\n Vaibhav Gupta: Oh, okay.\n \n 319\n 00:34:33.889 --> 00:34:34.690\n sahil: It is.\n \n 320\n 00:34:34.690 --> 00:34:43.710\n Vaibhav Gupta: It's not. It's not always about that. It's just like the model might just. It's just another tool in your toolbox for how you can get the model to output. What you want\n \n 321\n 00:34:44.260 --> 00:34:46.130\n Vaibhav Gupta: clues is one way to do it.\n \n 322\n 00:34:47.620 --> 00:35:02.900\n Dexter Horthy: And you can also do the thing we do. It's like, put the reasoning at the top and then dump the Json, and it sounds like this is just like, okay, if we want really targeted reasoning on each field. And maybe like, this is way more token efficient than having it output a bunch of extra. Json.\n \n 323\n 00:35:03.910 --> 00:35:15.300\n Vaibhav Gupta: Exactly, and you'll notice that you saw me iterate a little bit on this prompt over here, like I did a couple of things to go do this. But this goes into the very next tip that I want to really talk about.\n \n 324\n 00:35:15.410 --> 00:35:17.839\n Vaibhav Gupta: which is one\n \n 325\n 00:35:18.430 --> 00:35:26.989\n Vaibhav Gupta: it's called Rtfp. For those of you that don't know. Rtfm, it means read the fucking manual. Rtfp means read the fucking prompt.\n \n 326\n 00:35:27.397 --> 00:35:41.500\n Vaibhav Gupta: And I say that with a lot of love, because most people don't actually read the prompt. And you saw what I did when this didn't work over here. I just read the prompt I was like, oh, if I go back to the add description mechanism, let me give you a little bit more of a\n \n 327\n 00:35:41.850 --> 00:35:43.699\n Vaibhav Gupta: description of why I didn't like this.\n \n 328\n 00:35:45.120 --> 00:35:51.210\n Vaibhav Gupta: When I go read this, I'm like, oh, this thing over here. Maybe it's getting confused by the double comments.\n \n 329\n 00:35:52.690 --> 00:36:03.010\n Vaibhav Gupta: and you can see how that might be confusing to the model. So since I'm using comments like nested comments and comments, I'm like, okay, let me just try and simplify this problem for the model\n \n 330\n 00:36:03.340 --> 00:36:07.850\n Vaibhav Gupta: and give it that in a place where it can't be confused.\n \n 331\n 00:36:07.990 --> 00:36:11.340\n Vaibhav Gupta: and that was the intuition that I had out here.\n \n 332\n 00:36:12.834 --> 00:36:20.980\n Vaibhav Gupta: So it really just boils on to reading the prompt, because if we can read the prompt, then we can see what the model might be doing. And of course we can never actually know what's actually happening.\n \n 333\n 00:36:21.770 --> 00:36:28.940\n Vaibhav Gupta: but it allows us to actually know what it allows us to iterate a little bit faster, and then we can say, Oh, that isn't working. Let me go fix that.\n \n 334\n 00:36:29.080 --> 00:36:51.790\n Vaibhav Gupta: There's a question about why not use few shot prompting? There's a couple of reasons. Typically the way to have done few shot. Prompting in this example would have been me to actually go and write an example and then write out the answer. But that's not what I wanted. I just wanted the model to understand that it has the ability to go do this. It has the ability to list out facts before it actually spits out the speaker field.\n \n 335\n 00:36:52.160 --> 00:36:56.449\n Vaibhav Gupta: So I just wanted to give it the structure. So it understands the thing it has to mimic.\n \n 336\n 00:36:56.640 --> 00:36:58.450\n Vaibhav Gupta: I don't. It's not the contact.\n \n 337\n 00:36:58.970 --> 00:37:00.490\n Dexter Horthy: Go ahead, Dexter.\n \n 338\n 00:37:00.690 --> 00:37:23.570\n Dexter Horthy: And all this is again, is like, Okay, cool, like, yeah. Probably just outputting. Json is good enough. Outputting. Reasoning. 1st is a little bit better. Having reasoning in your Json. Fields is probably a little bit better. But if you're running this kind of thing a hundred 1,000 times a day, then a tiny half a percent improvement, either in efficiency or in speed or in token efficiency or in accuracy.\n \n 339\n 00:37:23.570 --> 00:37:34.359\n Dexter Horthy: is massively valuable. And this is what we talk about every week on this show like, how do you? How do you unlock those like near the top of the accuracy range? How do you push things even further.\n \n 340\n 00:37:34.720 --> 00:37:36.750\n Vaibhav Gupta: Yeah, how do you get another half a percent?\n \n 341\n 00:37:37.150 --> 00:37:41.709\n Vaibhav Gupta: And this isn't. Again, remember, this isn't say that this technique will work always.\n \n 342\n 00:37:42.270 --> 00:37:51.590\n Vaibhav Gupta: But it is another technique that you have available to yourself, just like we use this other technique to not spit out the entire dialog, but rather only spit out the index.\n \n 343\n 00:37:52.500 --> 00:37:59.219\n Vaibhav Gupta: And we use this other technique to say, Oh, dialogue index is actually a lot more tokens. Let's use purely the word index\n \n 344\n 00:37:59.420 --> 00:38:03.289\n Vaibhav Gupta: instead. So it spits out. The output. Tokens are way less.\n \n 345\n 00:38:03.290 --> 00:38:07.980\n Vaibhav Gupta: Hi, Chris, it's small things that can make a difference. And if I actually were to look at this.\n \n 346\n 00:38:08.160 --> 00:38:12.799\n Vaibhav Gupta: my punch actually says index itself, where to go.\n \n 347\n 00:38:12.800 --> 00:38:13.430\n Dexter Horthy: And.\n \n 348\n 00:38:13.430 --> 00:38:27.209\n Vaibhav Gupta: Index is probably wrong. I should actually probably use like index, because this is just a more popular token that the model will have understandings of, or rather than idx, even though idx is a single token. It's just more commonly understood.\n \n 349\n 00:38:27.970 --> 00:38:29.320\n Dexter Horthy: Existing processes.\n \n 350\n 00:38:30.306 --> 00:38:32.280\n Vaibhav Gupta: Cool, so.\n \n 351\n 00:38:32.280 --> 00:38:57.380\n sahil: Question, quick question. So we do this actually hundreds and thousands of times a day where we put out reasoning. And we use the reasoning as for another model, so is there a way to achieve or make it a bit more efficient? So we literally spit out clues, and these are at least a long sentence.\n \n 352\n 00:38:58.820 --> 00:39:02.800\n sahil: So any any tips or tricks do.\n \n 353\n 00:39:03.108 --> 00:39:10.200\n Vaibhav Gupta: If you really wanted, if you really wanted like if you really wanted that, I would actually put your reasoning afterwards\n \n 354\n 00:39:10.610 --> 00:39:12.060\n Vaibhav Gupta: like assessment.\n \n 355\n 00:39:14.540 --> 00:39:26.120\n Vaibhav Gupta: So if you want to do an eval thing right over here, description, final assessment of the speaker.\n \n 356\n 00:39:26.440 --> 00:39:35.159\n Vaibhav Gupta: Given any clues prior clues in comments, I received this\n \n 357\n 00:39:38.210 --> 00:39:44.669\n Vaibhav Gupta: and just like, let the model spit it out. And now you can use assessment as a thing. But now you'll see that assessment is actually kind of big.\n \n 358\n 00:39:44.850 --> 00:39:47.350\n Vaibhav Gupta: So what I'll do is like use phrases\n \n 359\n 00:39:52.283 --> 00:39:58.100\n Vaibhav Gupta: not complete sentences. And then I would also add into here\n \n 360\n 00:40:01.260 --> 00:40:02.150\n Vaibhav Gupta: assessment.\n \n 361\n 00:40:03.720 --> 00:40:11.949\n Vaibhav Gupta: So now I'll notice over here what it's doing, and it will just spit something out, and I would probably have to tweak this model. So sometimes Gt. 4 is not very good. So let me try. Anthropic.\n \n 362\n 00:40:13.510 --> 00:40:15.320\n Vaibhav Gupta: Is that the right model? We'll find out.\n \n 363\n 00:40:15.910 --> 00:40:17.390\n Vaibhav Gupta: Oh, that is not the right model.\n \n 364\n 00:40:18.290 --> 00:40:20.210\n Dexter Horthy: Dude, I think it's 1020.\n \n 365\n 00:40:23.440 --> 00:40:25.040\n Dexter Horthy: 2024, 1020.\n \n 366\n 00:40:25.670 --> 00:40:27.050\n Vaibhav Gupta: Custom, sonic.\n \n 367\n 00:40:27.640 --> 00:40:28.340\n Dexter Horthy: There you go!\n \n 368\n 00:40:29.880 --> 00:40:34.320\n Vaibhav Gupta: Oh, I don't have an Api key! One second. I will not be sharing my Api key this time around.\n \n 369\n 00:40:35.050 --> 00:40:38.260\n Dexter Horthy: Oh, that's why I come here every week.\n \n 370\n 00:40:38.390 --> 00:40:41.000\n Dexter Horthy: It's because you always you always leak at least one key.\n \n 371\n 00:40:41.400 --> 00:40:43.210\n Vaibhav Gupta: Also forget to deactivate it.\n \n 372\n 00:40:47.090 --> 00:40:50.010\n Vaibhav Gupta: Okay, let me.\n \n 373\n 00:40:53.290 --> 00:40:57.440\n Dexter Horthy: Yeah, and just answering it while he's doing that, answering the question on the thread.\n \n 374\n 00:40:58.544 --> 00:41:04.736\n Dexter Horthy: why not use few shot prompting. We talked about this a little bit. But it's basically\n \n 375\n 00:41:05.340 --> 00:41:11.930\n Dexter Horthy: the content of the examples tends to greatly steer the model's response.\n \n 376\n 00:41:12.290 --> 00:41:21.450\n Dexter Horthy: And like you can get, you can get the right structural results without actually putting content in your examples.\n \n 377\n 00:41:22.200 --> 00:41:23.030\n Vaibhav Gupta: Yes.\n \n 378\n 00:41:23.719 --> 00:41:37.190\n Vaibhav Gupta: so there we go. So now you can see over here when I switch this Claude, I actually get really nice things where it's assessment comes with this. And now you could plug this into your evals. We got a way less tokens out here. It's way. It's way shorter\n \n 379\n 00:41:38.360 --> 00:41:56.589\n Vaibhav Gupta: because we're not using complete sentences. So if you really care about evals and want to like you want to store the data anyway, go do that. But honestly, if you're up to me, I wouldn't do any of this Eval stuff online, I would have a separate process that pulls all my data down and runs a separate Eval, including the assessment for each of these segments off the raw data itself\n \n 380\n 00:41:57.240 --> 00:42:08.659\n Vaibhav Gupta: and just run a completely separate process. It's going to be way cheaper way faster, because don't add more latency to a pipeline that has this. Each of these things that you're generating here is latency. So a very latency, sensitive pipeline generally for speech to text.\n \n 381\n 00:42:10.240 --> 00:42:10.970\n Dexter Horthy: Cool.\n \n 382\n 00:42:12.075 --> 00:42:23.119\n Vaibhav Gupta: Cool. Let's talk about so at this point we've covered labels. Don't use uids. Don't use you urls use like indexes whenever possible and remap them programmatically to the right thing.\n \n 383\n 00:42:23.370 --> 00:42:33.389\n Vaibhav Gupta: We've talked about. Diarization don't emit the full transcript. Have the again, have the index, have the model represent something that is way better than the full transcript. In this case an index of the transcript\n \n 384\n 00:42:33.810 --> 00:42:38.110\n Vaibhav Gupta: we've talked about using inline comments to guide reasoning of sorts.\n \n 385\n 00:42:38.350 --> 00:42:53.019\n Vaibhav Gupta: We've talked about Re. Rtfd. Reading the prompt read it always, especially when you get stuck instead of trying to keep prompting more. Just keep reading it. We've talked about few shot prompting with structure, not with actual content, and how we can leverage that along the way.\n \n 386\n 00:42:53.770 --> 00:42:59.269\n Vaibhav Gupta: And I think the next thing I want to talk about is something that we've mentioned a few times. But it's all about Cogen.\n \n 387\n 00:42:59.990 --> 00:43:06.370\n Vaibhav Gupta: So I'm going to go ahead and pull up a random new file.\n \n 388\n 00:43:06.720 --> 00:43:19.140\n Anubhav: Hey, web Anupav! Here, before you move forward, I in my mind I'm still confused about using this technique where you somehow use Ginger to get an index on that array.\n \n 389\n 00:43:20.230 --> 00:43:22.640\n Vaibhav Gupta: I, yeah, good.\n \n 390\n 00:43:22.850 --> 00:43:29.829\n Anubhav: Versus using symbol tuning thing. So when to use what.\n \n 391\n 00:43:30.255 --> 00:43:30.680\n Vaibhav Gupta: Okay.\n \n 392\n 00:43:30.680 --> 00:43:35.760\n Vaibhav Gupta: okay, so just for context, let me just pull up a symbol to example. So then I, we can just talk about it.\n \n 393\n 00:43:39.840 --> 00:43:40.959\n Dexter Horthy: And it was the second or 3.rd\n \n 394\n 00:43:40.960 --> 00:43:42.890\n Vaibhav Gupta: Services. That's like the one\n \n 395\n 00:43:43.561 --> 00:43:51.359\n Vaibhav Gupta: I have symbol tuning right here. So the idea of symbol tuning is I want to do a classification example. I guess I'll do this\n \n 396\n 00:43:52.430 --> 00:43:55.900\n Vaibhav Gupta: symbol doing a\n \n 397\n 00:44:08.197 --> 00:44:17.240\n Vaibhav Gupta: I have a classification prompt instead of actually classifying the prompt. I want them all to spit out one of these categories, and I have a couple of different ways. I can go do this. Oh, that's interesting.\n \n 398\n 00:44:18.680 --> 00:44:22.739\n Vaibhav Gupta: I have a couple of different ways that I can go do this. But one of the ways is like.\n \n 399\n 00:44:23.400 --> 00:44:25.660\n Vaibhav Gupta: instead of the model actually spitting out\n \n 400\n 00:44:26.495 --> 00:44:35.540\n Vaibhav Gupta: all of my classes, I can. And instead of actually writing like the word refund in the prompt, I can write just the symbol, k. 1.\n \n 401\n 00:44:35.980 --> 00:44:37.750\n Vaibhav Gupta: And when the model runs this\n \n 402\n 00:44:37.950 --> 00:44:52.139\n Vaibhav Gupta: it will spit out K. 4, which then gets remapped to account issue for me automatically. The benefit of this approach is the model. Again, it's same. It's the exact same thing as the Youtube URL thing, where the model, when it sees the word account issue.\n \n 403\n 00:44:52.270 --> 00:45:02.139\n Vaibhav Gupta: it associates these tokens with something semantically meaningful. And what I want to do is my meaning of an account issue is actually encoded in my description way. Better than that.\n \n 404\n 00:45:02.140 --> 00:45:03.360\n Dexter Horthy: You want to say\n \n 405\n 00:45:03.610 --> 00:45:14.489\n Dexter Horthy: 0 attention on the label name, because that's for the coders and the program that's consuming this all attention on the description, so that I can control exactly what the Lm. Is going to output.\n \n 406\n 00:45:15.060 --> 00:45:21.420\n Vaibhav Gupta: Exactly exactly. It's about reducing the number of variability in the problem, Dexter said it beautifully.\n \n 407\n 00:45:21.930 --> 00:45:28.019\n Vaibhav Gupta: and symbol tuning is a technique. Lets me do this, the thing that we're talking about with diarization, where we output\n \n 408\n 00:45:28.633 --> 00:45:40.319\n Vaibhav Gupta: where we actually output like the actual index here, that's basically the same thing instead of the model outputting the actual text of the line, it's outputting the index of the line in the conversation.\n \n 409\n 00:45:40.660 --> 00:45:49.800\n Vaibhav Gupta: and instead of letting the model infer the index. Because I could do that. I don't actually have to write this. I could just let the model infer the index by writing something like this instead.\n \n 410\n 00:45:51.090 --> 00:45:52.950\n Dexter Horthy: Just in the model break. Yeah.\n \n 411\n 00:45:52.950 --> 00:45:58.019\n Vaibhav Gupta: Model could count. But why make the life harder for the model like this?\n \n 412\n 00:45:58.020 --> 00:46:04.910\n Dexter Horthy: Yeah. Now you're asking the model to count shit. Are you kidding me? That's terrifying. It's like, it's like, you know, when you do these coding agents, and you have, like\n \n 413\n 00:46:05.070 --> 00:46:11.650\n Dexter Horthy: no line numbers in the file versus every time you give it to the model, give it line numbers, and suddenly it can do these edits way. Better, right?\n \n 414\n 00:46:12.060 --> 00:46:20.929\n Vaibhav Gupta: Exactly, and this goes back to Rtfp. If I read this prompt even as a human. I know exactly what index this is without having to spend any time about it.\n \n 415\n 00:46:21.690 --> 00:46:26.039\n Vaibhav Gupta: But if I don't have these lines in there that becomes a lot harder for me to go, do.\n \n 416\n 00:46:26.520 --> 00:46:44.909\n Vaibhav Gupta: And I think it's small things like this that actually, dramatically change the quality of your outputs in a way that I think can make a huge difference. So I hope. I related the questions across the board, for the one of how simple tuning relates to diarization and the examples.\n \n 417\n 00:46:45.750 --> 00:47:15.680\n Dexter Horthy: And I. We won't go into this today, I think. But, like again, take all the advice from the Evals chapter and like, Don't go just applying all this stuff, willy, nilly like, get a real set. Understand what how your performance is today. Try changing these small things, you know whether it's like, Oh, I found a bug from production. Let me drop it in as a test case, and just change the prompt until I fix this one without breaking all the other ones, or even having a bigger Eval set, which is like, Hey, our accuracy is 84%. And if I make this change and run the exact same data through the pipeline. Now, it's 88%.\n \n 418\n 00:47:16.420 --> 00:47:18.610\n Vaibhav Gupta: Exactly exactly.\n \n 419\n 00:47:19.940 --> 00:47:20.570\n Vaibhav Gupta: Let's.\n \n 420\n 00:47:20.570 --> 00:47:21.000\n Dexter Horthy: Cool.\n \n 421\n 00:47:21.000 --> 00:47:25.330\n Vaibhav Gupta: Let's talk with the last part. Cogen. This is something we showed a couple of times, and this is kind of\n \n 422\n 00:47:25.790 --> 00:47:27.650\n Vaibhav Gupta: ex-related.\n \n 423\n 00:47:28.250 --> 00:47:45.929\n Dexter Horthy: Yeah, this directly leads from the other one, because it's again, it's like, how do we get the model to create invalid Json for good like, how? How can? By getting the model to create broken Json, you can actually get way. Better performance. And we'll talk about like, why, that works by looking like under the hood at like samplers and stuff right.\n \n 424\n 00:47:46.380 --> 00:47:48.290\n Vaibhav Gupta: Yeah, let's do that. That's actually a good idea.\n \n 425\n 00:47:48.630 --> 00:47:49.650\n Vaibhav Gupta: So in this case.\n \n 426\n 00:47:49.650 --> 00:47:50.480\n Dexter Horthy: I want to.\n \n 427\n 00:47:50.480 --> 00:47:55.809\n Vaibhav Gupta: Generate some code. And I'll say, a binary search tree\n \n 428\n 00:47:56.020 --> 00:48:04.820\n Vaibhav Gupta: with actually, no, let's do this. A sorting algorithm with merge sort.\n \n 429\n 00:48:05.260 --> 00:48:10.019\n Vaibhav Gupta: Alright cool. That's record that's redundant. So let's do this. Firstly.\n \n 430\n 00:48:11.540 --> 00:48:16.179\n Vaibhav Gupta: and it's gonna output this. And again, if I have a chat app, this is excellent.\n \n 431\n 00:48:17.680 --> 00:48:29.859\n Vaibhav Gupta: This is really really excellent. I could show this to the user. They'll be pretty happy, and we'll see the quality of the code right here. It looks pretty good. It has some comments and stuff in it. It looks generally useful.\n \n 432\n 00:48:30.490 --> 00:48:31.539\n Vaibhav Gupta: but the minute.\n \n 433\n 00:48:31.540 --> 00:48:44.149\n Dexter Horthy: This is the way models want to write code, by the way, like this is, if you if you just want to get the very best code performance. Let it write it between Markdown back ticks, because that is what is the majority present in the training set.\n \n 434\n 00:48:44.490 --> 00:48:45.060\n Vaibhav Gupta: Yeah.\n \n 435\n 00:48:45.170 --> 00:48:54.929\n Vaibhav Gupta: Now, I'm gonna change this to actually return a data model. Because, hey, I want the code so I can go find it. I don't do some parsing. I want to render it just the code part without all this prefix. Or maybe I want to go run it and go do something.\n \n 436\n 00:48:54.930 --> 00:49:00.789\n Dexter Horthy: You don't want to have to write code to strip out that like python back ticks thing because you're just going to turn around and run it. Maybe.\n \n 437\n 00:49:01.310 --> 00:49:05.699\n Vaibhav Gupta: And now we got this, and I don't actually know the quality of this code.\n \n 438\n 00:49:06.130 --> 00:49:22.800\n Vaibhav Gupta: but we'll see. All I do know is it did output a lot of things, and I want everyone to know something very, very important here. This is actually what the model output. This is raw. I just copied. Directly the string the model came out with. If I go back to the Tokenizer I'll show you. I want to show everyone what this means.\n \n 439\n 00:49:24.500 --> 00:49:26.120\n Vaibhav Gupta: We can see what it did.\n \n 440\n 00:49:26.600 --> 00:49:29.239\n Dexter Horthy: Yo slash and n are 2 different tokens.\n \n 441\n 00:49:29.560 --> 00:49:31.180\n Vaibhav Gupta: Yeah, exactly. So it's actually.\n \n 442\n 00:49:31.180 --> 00:49:32.250\n Dexter Horthy: That's crazy.\n \n 443\n 00:49:32.250 --> 00:49:41.360\n Vaibhav Gupta: It's outputting a bunch of space characters. It's it's not actually outputting code. It's outputting something slightly different. It's something that looks like code.\n \n 444\n 00:49:41.700 --> 00:49:47.359\n Dexter Horthy: Will you? Sorry? Can I screenshot that? And then can you drop the other output into the tokenizer as well.\n \n 445\n 00:49:48.360 --> 00:49:49.030\n Vaibhav Gupta: Yeah. Why not?\n \n 446\n 00:49:49.030 --> 00:49:51.060\n Dexter Horthy: Back and let me get a screenshot real quick.\n \n 447\n 00:49:52.910 --> 00:49:54.870\n Vaibhav Gupta: Yeah, I'll put side by side. How about that?\n \n 448\n 00:49:55.180 --> 00:49:59.260\n Dexter Horthy: Okay, yeah, because I think this is really important.\n \n 449\n 00:50:01.780 --> 00:50:02.400\n Vaibhav Gupta: Okay.\n \n 450\n 00:50:09.070 --> 00:50:14.369\n Dexter Horthy: So if you get rid of the back ticks and the actual like, preamble and stuff, how do the token.\n \n 451\n 00:50:14.370 --> 00:50:23.309\n Vaibhav Gupta: No, I'll I'll leave that in there, actually. Because I think it's important. And this one has like a Java example as well. So why not get rid of the Java example.\n \n 452\n 00:50:23.840 --> 00:50:24.500\n Dexter Horthy: Yeah.\n \n 453\n 00:50:24.680 --> 00:50:26.857\n Vaibhav Gupta: Just to like, keep it in.\n \n 454\n 00:50:29.100 --> 00:50:34.660\n Vaibhav Gupta: There's something in here cool.\n \n 455\n 00:50:34.770 --> 00:50:38.229\n Vaibhav Gupta: and this seems to have a print example as well. So we leave that in there.\n \n 456\n 00:50:38.630 --> 00:50:54.549\n Vaibhav Gupta: What we'll notice here is not. It's not really about the token counts or anything else. What's really important here is like the quality of the code that's being generated. 1st thing that we notice upfront is recursively sort both halves. So this comes out. And then, if we go look at this all these backslash ends\n \n 457\n 00:50:54.940 --> 00:51:01.370\n Vaibhav Gupta: are actually having to be forcefully generated by the model, to be correctly syntactical. Json out of here.\n \n 458\n 00:51:02.060 --> 00:51:05.690\n Dexter Horthy: Because you can't have new lines in Json. You have to have escaped new lines.\n \n 459\n 00:51:05.940 --> 00:51:11.489\n Vaibhav Gupta: Exactly, instead of letting the model just do escape new lines. So what if we just told the model to go do that instead?\n \n 460\n 00:51:11.740 --> 00:51:26.470\n Vaibhav Gupta: What we'll find is code description. Use, use triple use back, take use triple backticks, the format code, code.\n \n 461\n 00:51:26.930 --> 00:51:28.010\n Vaibhav Gupta: python.\n \n 462\n 00:51:30.680 --> 00:51:34.639\n Vaibhav Gupta: and let's go read the Prompt. Let's see what the prompt looks like. This is what the prompt looks like.\n \n 463\n 00:51:35.070 --> 00:51:37.020\n Vaibhav Gupta: Use triple backfix to read the prompt\n \n 464\n 00:51:39.600 --> 00:51:42.870\n Vaibhav Gupta: And now, when I go run this, what I get\n \n 465\n 00:51:42.980 --> 00:51:46.589\n Vaibhav Gupta: is the model output code exactly how I was outputting before.\n \n 466\n 00:51:48.320 --> 00:51:51.280\n Vaibhav Gupta: but in a way that still allows me to do structured promptly.\n \n 467\n 00:51:51.900 --> 00:52:12.870\n Dexter Horthy: So this is not valid, Json, and like the subtle thing here is like. And this is kind of like, I think we're having a conversation yesterday about like one of the cool things you can do with Bamel, and why, having a parser that is separate from the that is outside of the model itself is really powerful is because you can let the model use regular new lines and its output, and then turn them back into J, like regular, like Json, that works.\n \n 468\n 00:52:14.330 --> 00:52:19.900\n Vaibhav Gupta: Yes, so now let's go. Do this. Now, I want to make this as a lesson plan\n \n 469\n 00:52:20.140 --> 00:52:24.469\n Vaibhav Gupta: for the following, input as a lesson with diffs.\n \n 470\n 00:52:26.250 --> 00:52:30.260\n Vaibhav Gupta: So now, what I'm going to do is I'm going to output an array of code snippets.\n \n 471\n 00:52:30.700 --> 00:52:31.970\n Vaibhav Gupta: Not one\n \n 472\n 00:52:32.970 --> 00:52:39.719\n Vaibhav Gupta: but multiple arrays. And then I'm gonna say, make a plan. To for to go do this example.\n \n 473\n 00:52:41.970 --> 00:52:46.170\n Vaibhav Gupta: Section one. Blah blah blah section 2, blah blah blah blah\n \n 474\n 00:52:49.180 --> 00:52:56.280\n Vaibhav Gupta: cool. And again, what do you think? Few shop the example of using comments as guiding principles? We're gonna do the same thing here.\n \n 475\n 00:52:57.200 --> 00:52:59.609\n Vaibhav Gupta: and then we'll add a little title here, string\n \n 476\n 00:53:02.270 --> 00:53:10.530\n Dexter Horthy: This is funny. This is what I actually did for a workshop a couple weeks ago, was we had said, Hey, here's the final product, output it as sections in a lesson plan.\n \n 477\n 00:53:12.130 --> 00:53:13.819\n Vaibhav Gupta: So now we're gonna do the same thing.\n \n 478\n 00:53:15.670 --> 00:53:18.080\n Vaibhav Gupta: And now what the model is, I'm fixing this bug.\n \n 479\n 00:53:18.390 --> 00:53:23.029\n Dexter Horthy: I mean, this is cool. But why, why would you want to do it this way? Why would you want to do this?\n \n 480\n 00:53:23.030 --> 00:53:23.880\n Dexter Horthy: It's like us.\n \n 481\n 00:53:24.140 --> 00:53:34.370\n Vaibhav Gupta: I'll show you the output, because I think the output will make it more clear. So the 1st thing is, I wanted to build a lesson plan so I did reasoning for like what lesson plan I wanted to go do. So it said, what we're gonna do this.\n \n 482\n 00:53:34.540 --> 00:53:36.580\n Vaibhav Gupta: then it's going to actually output the code\n \n 483\n 00:53:36.920 --> 00:53:47.039\n Vaibhav Gupta: and create a merge function that combines 2 sort of arrays. Great create a basic merge sort function with recursion. So it's actually incrementing it. Now you can imagine that I walk someone through the code\n \n 484\n 00:53:47.360 --> 00:53:48.620\n Vaibhav Gupta: one by one.\n \n 485\n 00:53:49.850 --> 00:54:03.160\n Vaibhav Gupta: right. And now it's intending with array, splitting recursive calls. So now it's incrementally going to do this. Now I can build a ui on top of this. That literally has step one step, 2, step 3, and teach someone merge sort with this benefit along the way.\n \n 486\n 00:54:04.580 --> 00:54:10.440\n Vaibhav Gupta: right and along the whole time. If I get rid of this section I will. I will literally just comment this part out.\n \n 487\n 00:54:11.750 --> 00:54:15.319\n Vaibhav Gupta: I'll show you how much harder it becomes for the model to actually generate this\n \n 488\n 00:54:19.140 --> 00:54:24.490\n Vaibhav Gupta: like this is now like becoming significantly harder\n \n 489\n 00:54:24.720 --> 00:54:29.500\n Vaibhav Gupta: for the model to actually keep track of its own code, because even as a developer\n \n 490\n 00:54:29.750 --> 00:54:43.019\n Vaibhav Gupta: this would be very, very hard for me to even unread and understand this and most of the training data and the models Codegen doesn't actually have backslash ends as this. It has it as the actual backslash end.\n \n 491\n 00:54:43.250 --> 00:54:52.550\n Vaibhav Gupta: So code quality that you're getting is going to be way worse. So when we go to like a harder problem, let's go into a harder problem, because merge sort is something that we all know, like even the basic models can go do.\n \n 492\n 00:54:54.820 --> 00:54:58.160\n Vaibhav Gupta: Create a what is it? What's a harder problem next, sir?\n \n 493\n 00:54:59.129 --> 00:55:04.069\n Dexter Horthy: Kubernetes operator to spin up Rds. Instances in Golang.\n \n 494\n 00:55:08.830 --> 00:55:10.760\n Vaibhav Gupta: To spin up our.\n \n 495\n 00:55:10.760 --> 00:55:14.049\n Dexter Horthy: Spin up yeah instances and go lang.\n \n 496\n 00:55:15.080 --> 00:55:16.789\n Vaibhav Gupta: I have no idea.\n \n 497\n 00:55:18.680 --> 00:55:22.449\n Vaibhav Gupta: I have no idea what half those words mean, because sadly, I work in algorithms land.\n \n 498\n 00:55:23.300 --> 00:55:25.390\n Vaibhav Gupta: and we're seeing what the model is. So I want you.\n \n 499\n 00:55:25.390 --> 00:55:26.620\n Dexter Horthy: Oh, it made a diff.\n \n 500\n 00:55:26.960 --> 00:55:28.020\n Dexter Horthy: Yes.\n \n 501\n 00:55:28.020 --> 00:55:29.360\n Vaibhav Gupta: Maldo's made a death.\n \n 502\n 00:55:29.510 --> 00:55:41.060\n Vaibhav Gupta: I also want us to notice a couple other things. The model actually, intuitively just put out back tick new lines. Anyway, it actually was like, you know, what I am not going to put out backslash ends. I'm just going to spit out this.\n \n 503\n 00:55:41.230 --> 00:55:43.789\n Vaibhav Gupta: So model intuitively did this for us\n \n 504\n 00:55:44.930 --> 00:55:50.049\n Vaibhav Gupta: without us even having to prompt at that. And that just goes to show that the model's intuitive behavior\n \n 505\n 00:55:50.470 --> 00:55:57.399\n Vaibhav Gupta: is not to spit out, escaped Json, and the reason it probably did this\n \n 506\n 00:55:57.670 --> 00:56:08.230\n Vaibhav Gupta: is because go is just a lot more technical than python or typescript and other things. So the minute it got to like a hard mode problem. It did the most basic things for itself.\n \n 507\n 00:56:09.290 --> 00:56:16.300\n Dexter Horthy: Yeah, you wanna pop back to the whiteboard for really quick and just highlight. I I wanna highlight this sampling part of this\n \n 508\n 00:56:17.900 --> 00:56:19.108\n Vaibhav Gupta: So you have it too.\n \n 509\n 00:56:19.350 --> 00:56:20.200\n Dexter Horthy: Yeah. Yeah.\n \n 510\n 00:56:24.300 --> 00:56:24.790\n Vaibhav Gupta: There you go!\n \n 511\n 00:56:24.790 --> 00:56:38.520\n Dexter Horthy: So, okay, so you got that up scroll down a little bit. So basically like, if if you know how samplers work, essentially, you have at any given point. You have, you know, the models writing code, and it's writing, like, you know, code\n \n 512\n 00:56:38.690 --> 00:56:44.490\n Dexter Horthy: import OS, and then at any given point, it's it's we're at. Let's say we're right here.\n \n 513\n 00:56:44.760 --> 00:56:58.430\n Dexter Horthy: and we're generating like. Then we're asking what's the next token? At this moment there is, you know, and a distribution of what the next token is going to be right. And in this case it's almost always going to be like\n \n 514\n 00:56:58.530 --> 00:57:08.779\n Dexter Horthy: new line kind of classic new line. And then there's going to be a long tail of other characters. That might be next right? You might have, you know, semicolon here.\n \n 515\n 00:57:10.260 --> 00:57:29.840\n Dexter Horthy: because maybe some code has like import OS semicolon. And then another import. Maybe if it's red code serialized in Json, maybe there is a backslash here which is going to lead it to correctly type the slash N, and maybe there's some other characters here defined by your temperature, right of like different probabilities of that. That's the next token?\n \n 516\n 00:57:30.270 --> 00:57:31.310\n Dexter Horthy: Does it make sense.\n \n 517\n 00:57:31.830 --> 00:57:32.460\n Vaibhav Gupta: Yup!\n \n 518\n 00:57:33.040 --> 00:57:47.999\n Dexter Horthy: So when you put on strict mode or strict Json mode, and even in some of the more like old school function calling modes, they're starting to enforce this. Basically that is going to when the model gets to its like time to do the correct output.\n \n 519\n 00:57:48.030 --> 00:58:10.569\n Dexter Horthy: It's just going to X out anything that would break the Json schema, which means that a new line is not a valid character, because a new line is not valid, Json, and this is why, when people say, like, you know, using strict mode reduces the accuracy of your outputs, it's because now you're removing the big one, and you have a very, very like\n \n 520\n 00:58:10.730 --> 00:58:30.700\n Dexter Horthy: tight distribution of the other things. Now these probabilities get balanced out, and you have a bunch of things that are like probably next, but like not clear. And so you're likely to get weird janky code with like semicolons in it, instead of backslashes, or even like invalid syntax, because you're not letting the model write code in the way that it's been trained to write code.\n \n 521\n 00:58:31.550 --> 00:58:38.520\n Vaibhav Gupta: Yeah. And this applies not just for Cogen, but applies to any domain where anytime you're having the model not pick its best token.\n \n 522\n 00:58:38.920 --> 00:58:44.290\n Vaibhav Gupta: You're basically telling the model like you know better than model, which may be true in some scenarios. I want to articulate that.\n \n 523\n 00:58:44.910 --> 00:58:50.219\n Vaibhav Gupta: But most of the time in machine learning. What we've learned is, let the model do what it does best\n \n 524\n 00:58:50.350 --> 00:59:05.340\n Vaibhav Gupta: and just let it output the best token. And in computer vision we had this problem all the time, where we always let the model, like we trying to be very clever about the model where we do. Oh, let's do this pre-processing. Let's do this post-processing. It turned out the best answer, as all the Vlms have showed.\n \n 525\n 00:59:05.470 --> 00:59:06.670\n Vaibhav Gupta: is literally just\n \n 526\n 00:59:07.100 --> 00:59:15.579\n Vaibhav Gupta: give it all to the model. Let it decide, and I think the same thing is true with token, generation, or everything else too like. Don't try and be clever with token generation. Let's let the model pick the best token.\n \n 527\n 00:59:17.052 --> 00:59:34.890\n Vaibhav Gupta: I think that's all we have time for today in terms of actual topics and prompting techniques. I hope that this was incredibly useful for everyone else. What we'll do for the next 1520 min is I'll go to the discord, and I'll see what prompts that we have submitted, if we have any at all.\n \n 528\n 00:59:35.290 --> 00:59:35.810\n Vaibhav Gupta: and.\n \n 529\n 00:59:35.810 --> 00:59:36.930\n Dexter Horthy: There's a couple in here.\n \n 530\n 00:59:37.350 --> 00:59:40.069\n Vaibhav Gupta: Oh, there are! Oh, that's actually more than I expected!\n \n 531\n 00:59:40.993 --> 00:59:41.720\n Dexter Horthy: There's 2.\n \n 532\n 00:59:41.890 --> 00:59:43.740\n Vaibhav Gupta: Exact. That's more than I expected.\n \n 533\n 00:59:45.520 --> 00:59:47.419\n Vaibhav Gupta: Here is, I'll go. Do this.\n \n 534\n 00:59:47.600 --> 00:59:49.440\n Vaibhav Gupta: Let's just bring this one up.\n \n 535\n 00:59:51.290 --> 01:00:08.250\n Vaibhav Gupta: I use this prompt to evaluate Llms on their ability to make sense of Lm generated events. But before we go into this, does anyone have questions while I go read this prompt that people want to go, ask for, feel free to come off mute, and just ask if you, after you raise your hand and come on in.\n \n 536\n 01:00:11.660 --> 01:00:20.379\n Jonathan Ng: So I do have a question about that code. Gen stuff. Just because, like, when we're talking, yeah, I do agree that like letting the\n \n 537\n 01:00:20.510 --> 01:00:36.900\n Jonathan Ng: Codegen do its thing is much better and produces a lot better results. But, on the other hand, like, when you're working in an established code base. Usually it has its own like style and things like that.\n \n 538\n 01:00:37.441 --> 01:00:39.729\n Jonathan Ng: How do you resolve that problem?\n \n 539\n 01:00:41.710 --> 01:00:57.629\n Vaibhav Gupta: Yeah, my desk might have his own opinions. My answer for all that is always the same thing, which is just add more software on top of it. If you want stuff to be formatted in a good way, literally just run a linter on the generated code, it will be formatted exactly how you want it to be formatted.\n \n 540\n 01:00:57.920 --> 01:01:10.730\n Vaibhav Gupta: If you don't have a linter with an opinionated formatting, it's probably not mimicking that if you, if you feel like you don't have the linther rules. Go write a quick lm, prompt to look at your existing code, generate Linter rules off of that, and then go run the formatter\n \n 541\n 01:01:11.515 --> 01:01:11.990\n Vaibhav Gupta: but.\n \n 542\n 01:01:11.990 --> 01:01:35.149\n Dexter Horthy: Oh, because what I've seen in coding agents is a lot of like, okay, cool. Read a couple like, if you're using clock code or something. It reads a couple files, and then what it's read in the code base already kind of propagates down to the next code it generates, but it almost sounds like what would be much more efficient would be like. Take a couple of the files and have the model generate either like Hardcore Linter, because not all style can be enforced by a linter right. The linters are getting better, but not everything.\n \n 543\n 01:01:35.150 --> 01:01:47.560\n Dexter Horthy: but, like either, create a biome rule set or an Eslint rule set, or whatever it is, or even just create a prompt that is like, here's a bunch of examples of how we write code that. So the model doesn't have to read entire files, but you capture it succinctly.\n \n 544\n 01:01:47.560 --> 01:02:10.270\n Vaibhav Gupta: Yeah, and to do a little bit of extra leg work to find the models that represent it. And I think this is the same way, if you think about like just hiring a new developer, there's ways to build your Dev team where you're like. People, my dev team will just figure out some coding format and alignment. But if you really care about code quality and want it to be consistent, then you add a linter, you add a formatter, and then it becomes uniform automatically.\n \n 545\n 01:02:10.650 --> 01:02:25.470\n Vaibhav Gupta: So like. And the most ultimate way to do this is the end up using some language like Go, which, like forces like, if you want to export things that has to be capital like developers, don't even get a choice or use black, which is like a very opinionated python format which says, no configuration. It's just the way it is.\n \n 546\n 01:02:25.720 --> 01:02:28.829\n Vaibhav Gupta: and I think the same things apply for like stylistic guidelines.\n \n 547\n 01:02:30.740 --> 01:02:31.319\n Vaibhav Gupta: Does that.\n \n 548\n 01:02:31.320 --> 01:02:32.430\n Jonathan Ng: That makes sense.\n \n 549\n 01:02:34.244 --> 01:02:40.235\n Jonathan Ng: Yeah, I think. There's also like in cursor, for example, there are also cursor rules,\n \n 550\n 01:02:41.220 --> 01:02:46.980\n Jonathan Ng: which I think also help with this, although I haven't really explored a lot of it.\n \n 551\n 01:02:47.290 --> 01:02:48.579\n Jonathan Ng: Person would say.\n \n 552\n 01:02:48.580 --> 01:02:58.070\n Vaibhav Gupta: Yeah, cursor rules are a great way to go do that as well. But I think, like, if you're building an app that generates code. Then you can't use cursor rules. So then you have to build your own equivalent of cursor rules.\n \n 553\n 01:03:00.110 --> 01:03:12.239\n Vaibhav Gupta: That's really, if you're using cursor, then cursor rule should hopefully just fix that for you while cursor does this. Since cursor has built a system like this, they basically added a lot of software on top of their codegen\n \n 554\n 01:03:12.380 --> 01:03:15.420\n Vaibhav Gupta: to make their Cogen more in line with your code base.\n \n 555\n 01:03:16.660 --> 01:03:17.649\n Vaibhav Gupta: Oh, come on.\n \n 556\n 01:03:17.650 --> 01:03:20.830\n Jonathan Ng: That makes sense alright. Thank you.\n \n 557\n 01:03:21.310 --> 01:03:26.130\n Vaibhav Gupta: Alright, thanks, Jonathan. One last question. And then I'm gonna go into this prompt now that I've actually read it\n \n 558\n 01:03:29.520 --> 01:03:30.390\n Vaibhav Gupta: cool.\n \n 559\n 01:03:30.720 --> 01:03:34.520\n Dexter Horthy: Going once going twice, all right. Hack night of Github.\n \n 560\n 01:03:35.200 --> 01:03:35.890\n Vaibhav Gupta: Okay.\n \n 561\n 01:03:36.200 --> 01:03:44.060\n Vaibhav Gupta: So this is a prompt where it seems to be like someone wants to look at Lm, and come up with like some sort of like a plan for the most of this event.\n \n 562\n 01:03:44.840 --> 01:03:51.369\n Dexter Horthy: It looks like the the prompt is basically come up with a plan. And the rest of it is just input context, right?\n \n 563\n 01:03:51.370 --> 01:03:52.510\n Vaibhav Gupta: Yeah, exactly.\n \n 564\n 01:03:52.780 --> 01:03:57.099\n Vaibhav Gupta: So the 1st thing that I'll notice is like, let's just go back and write this prompt\n \n 565\n 01:03:59.357 --> 01:04:03.630\n Vaibhav Gupta: and actually, oh, yeah, plan, dot demo\n \n 566\n 01:04:06.890 --> 01:04:09.240\n Vaibhav Gupta: function, make event.\n \n 567\n 01:04:09.760 --> 01:04:12.959\n Vaibhav Gupta: Well, actually, I'm not gonna actually do this. I don't want this.\n \n 568\n 01:04:13.630 --> 01:04:14.190\n Dexter Horthy: Yeah.\n \n 569\n 01:04:21.290 --> 01:04:25.980\n Vaibhav Gupta: And this thing will make this a better function.\n \n 570\n 01:04:26.960 --> 01:04:30.620\n Vaibhav Gupta: Okay? So the 1st thing I'll notice about this is.\n \n 571\n 01:04:31.030 --> 01:04:35.229\n Vaibhav Gupta: oh, what the heck did. An update. Oh, that's so funny. We have a bug, we have a\n \n 572\n 01:04:37.150 --> 01:04:40.889\n Vaibhav Gupta: that's so funny. We have a bug where com in my.\n \n 573\n 01:04:40.890 --> 01:04:43.719\n Dexter Horthy: Is it coming as like Markdown, front matter or something?\n \n 574\n 01:04:43.720 --> 01:04:49.209\n Vaibhav Gupta: It's like dash, dash, dashes, comments. I think we strip it out that's so funny.\n \n 575\n 01:04:50.290 --> 01:04:51.090\n Dexter Horthy: Yes, I.\n \n 576\n 01:04:51.280 --> 01:04:55.620\n Vaibhav Gupta: So like the 1st thing when it comes to. So let's let's catch everyone else on what this prompt is.\n \n 577\n 01:04:56.210 --> 01:05:02.889\n Vaibhav Gupta: This prompt is pretty simple. It does come up with a plan to make the most of this event, and then you dump the actual event from like Luma or something else out there.\n \n 578\n 01:05:03.150 --> 01:05:09.409\n Vaibhav Gupta: Now. The most intuitive way is to just send that to the prompt and like, if we send the Chat, Gpt, or go, do something\n \n 579\n 01:05:09.580 --> 01:05:11.360\n Vaibhav Gupta: so like if I have.\n \n 580\n 01:05:11.360 --> 01:05:17.659\n Dexter Horthy: By the way, if whoever wrote that prompt is is here, feel free to come off mute and give a little more context around what this is, and what you use it for.\n \n 581\n 01:05:17.660 --> 01:05:35.410\n John Chen: Yeah, so I'm the one who posted it. This is how I you know Luma has, like a hundred events a month in San Francisco, and I don't read them all manually at first, st so I use something like this to try to surface the ones I want to go to, and this how I know about Babel. So you know a pretty crude.\n \n 582\n 01:05:35.410 --> 01:05:35.769\n Dexter Horthy: There you go!\n \n 583\n 01:05:35.770 --> 01:05:40.950\n John Chen: For me, and I just want to make it a little more comprehensive, systemic and all that.\n \n 584\n 01:05:41.120 --> 01:05:48.490\n John Chen: And you know I just don't have an actual process for it, but I know it. Kinda it works for me to make the sense of San Francisco texting.\n \n 585\n 01:05:49.020 --> 01:05:50.870\n Vaibhav Gupta: And I think I could do more with it.\n \n 586\n 01:05:51.600 --> 01:05:56.449\n Vaibhav Gupta: Yeah. So over here, you can see what it come up with. And this is typically what you'd expect out of this sort of thing\n \n 587\n 01:05:56.560 --> 01:06:08.800\n Vaibhav Gupta: that said, what I actually want is, and this is step number one, literally just stop asking the model to actually go do like, spit out the plan as a string, have the model actually spit out a preparation sub for you.\n \n 588\n 01:06:09.240 --> 01:06:13.369\n Vaibhav Gupta: I like what to go do. And when you actually go, do this, let's actually paste.\n \n 589\n 01:06:13.570 --> 01:06:15.329\n Vaibhav Gupta: I'll just copy and paste this in myself.\n \n 590\n 01:06:16.960 --> 01:06:21.110\n Vaibhav Gupta: I think I copied and pasted this example as well. So I'll make this test case\n \n 591\n 01:06:23.490 --> 01:06:25.944\n Dexter Horthy: I like the discord, only lets you copy one time.\n \n 592\n 01:06:26.630 --> 01:06:28.289\n Vaibhav Gupta: I know that's so funny.\n \n 593\n 01:06:32.330 --> 01:06:40.080\n Vaibhav Gupta: Great. So I have this test case now, and when I go run the instead of the model actually spitting this stuff up here. It's actually giving me something a little bit better\n \n 594\n 01:06:40.530 --> 01:06:50.320\n Vaibhav Gupta: of like what I can go talk to. And in this case I have a way, better experience like who I actually should go meet. And I can make this more targeted by simply just changing my schema\n \n 595\n 01:06:50.460 --> 01:06:53.000\n Vaibhav Gupta: class networking.\n \n 596\n 01:06:53.780 --> 01:06:54.800\n Vaibhav Gupta: Oh, God!\n \n 597\n 01:06:55.320 --> 01:07:00.610\n Vaibhav Gupta: Class. Networking opportunity.\n \n 598\n 01:07:04.880 --> 01:07:18.020\n Vaibhav Gupta: Okay. Name, season, string, value, value, high medium, low description. How valuable the.\n \n 599\n 01:07:18.530 --> 01:07:20.590\n Dexter Horthy: Yeah, we'll we'll push all this. Go, John.\n \n 600\n 01:07:20.590 --> 01:07:29.260\n Vaibhav Gupta: The person is to myself and my career polls.\n \n 601\n 01:07:29.810 --> 01:07:42.229\n Dexter Horthy: Yeah, the other thing, I think, would benefit a lot here is like a lot more context about me and who I am, although I guess if you're probably pasting this into Chat Gpt, then you have your memory and stuff at play to kind of like, give that grounding.\n \n 602\n 01:07:42.750 --> 01:07:53.100\n Vaibhav Gupta: So the name main thing that you'll notice here is I, I'm actually gonna change this. I'm gonna make this a lot better. I'm gonna say that this is I wanna meet these people value. And then it's gonna dump out the reason for why.\n \n 603\n 01:07:53.380 --> 01:07:59.349\n Vaibhav Gupta: And you notice that actually changed out a lot of the more general, generally specific ones like this was very\n \n 604\n 01:08:00.030 --> 01:08:04.559\n Vaibhav Gupta: like random, but this is a lot more pointed, oriented. I can go act on this.\n \n 605\n 01:08:04.700 --> 01:08:07.179\n Vaibhav Gupta: What else I can do here is, I can say, like.\n \n 606\n 01:08:07.390 --> 01:08:09.880\n Vaibhav Gupta: I can actually change this. I like entity\n \n 607\n 01:08:13.960 --> 01:08:26.500\n Vaibhav Gupta: last company, right company, name, last person, type.\n \n 608\n 01:08:27.029 --> 01:08:30.369\n Vaibhav Gupta: And see you want this.\n \n 609\n 01:08:30.960 --> 01:08:45.810\n Vaibhav Gupta: And now, when I go run this, it should actually spit out what I actually want. So now, I can actually go like specifically look these up. And I can build a small little ui around this like a react component that actually renders these in with like Linkedin searches and follow up sequences on top of that.\n \n 610\n 01:08:46.270 --> 01:08:58.950\n Vaibhav Gupta: So then I can just go ahead and say, Oh, here's a link to the company's URL. Here's who they are, and here's how they are. And this is just like Aiml. Speakers cool. No one specific was highlighted on there. So I don't actually have, like anyone ambiguous people are ambiguous. There.\n \n 611\n 01:08:59.420 --> 01:09:23.650\n Dexter Horthy: But if you put 1st name last name you could also probably force it to like it wouldn't even output that right like if you. Wanna if you want to drive the output to the point where it's like, Okay, I only want things that are actually useful. I don't want this kind of like hallucinating, sloppy like talk to aiml speakers like, Okay, that's bullshit, like I. I only want like you to pull out people with actual names. So it's like, if there was a speaker name in the description of like, this person will be speaking, then it could go tell you some things about them.\n \n 612\n 01:09:28.160 --> 01:09:31.730\n Vaibhav Gupta: And we can guarantee that at least the 1st name or the last name exists.\n \n 613\n 01:09:32.340 --> 01:09:34.890\n Vaibhav Gupta: and then all other entities will just get dropped.\n \n 614\n 01:09:36.420 --> 01:09:37.999\n Vaibhav Gupta: So we still get these.\n \n 615\n 01:09:38.370 --> 01:10:04.459\n Vaibhav Gupta: But then we they actually just get dropped from our final parsing, because, like, it doesn't meet the constraint that we need, which is 1st and last name need to actually exist. So even if they all generates it, you can drop it. But the whole point of this is, instead of actually having the model spit out the string. What I really did is I focus on what I care about what I want to see and what I want to personally derive out of this prompt, which is, I think, what John you're trying to do is like, see if things are going to help you like grow out of these events.\n \n 616\n 01:10:04.590 --> 01:10:09.549\n Vaibhav Gupta: So then I would just focus the specific stuff on here to say, like.\n \n 617\n 01:10:09.970 --> 01:10:14.919\n Vaibhav Gupta: focus on how it helps me and myself. It is to myself and my career, goals.\n \n 618\n 01:10:15.250 --> 01:10:23.969\n Dexter Horthy: Yeah, guide the reasoning with as much context as possible. And I bet if you took this Json object and dropped into V 0, you could make a nice ui for this, and you know 60 seconds.\n \n 619\n 01:10:24.620 --> 01:10:30.690\n Vaibhav Gupta: Oh, yeah, I bet this is same in line with this.\n \n 620\n 01:10:31.170 --> 01:10:33.670\n Vaibhav Gupta: Make a ui, for\n \n 621\n 01:10:41.910 --> 01:10:43.610\n Vaibhav Gupta: I'll probably go do something.\n \n 622\n 01:10:45.025 --> 01:10:52.400\n Vaibhav Gupta: And I'll go build some out something ui for me. And now we have a full app that we can just go use directly without having to think about it.\n \n 623\n 01:10:54.200 --> 01:10:56.439\n Vaibhav Gupta: with small little rendering stuff as well.\n \n 624\n 01:10:57.120 --> 01:10:58.909\n Vaibhav Gupta: Come on. This takes a while.\n \n 625\n 01:10:59.440 --> 01:11:01.520\n Vaibhav Gupta: and then you can. Do you want with your app?\n \n 626\n 01:11:04.200 --> 01:11:05.319\n Dexter Horthy: We got time for one more prompt\n \n 627\n 01:11:09.200 --> 01:11:11.120\n Dexter Horthy: saw someone else typing in.\n \n 628\n 01:11:12.540 --> 01:11:13.579\n sahil: Sorry. Go ahead.\n \n 629\n 01:11:13.850 --> 01:11:16.700\n sahil: Can I just drop the prompt in the chat, or should I.\n \n 630\n 01:11:16.700 --> 01:11:20.709\n Vaibhav Gupta: I'll probably be too long, but you will have to do it in the discord sadly.\n \n 631\n 01:11:20.710 --> 01:11:21.999\n sahil: Oh, yeah, yeah, okay. Cool.\n \n 632\n 01:11:22.000 --> 01:11:28.049\n Dexter Horthy: Prashant had another one as well. That was answering questions with like verbosity, and things like that.\n \n 633\n 01:11:28.050 --> 01:11:31.960\n Prashanth Rao: Yeah. So so actually, you kind of answered many of these in the previous example.\n \n 634\n 01:11:31.960 --> 01:11:32.809\n Vaibhav Gupta: Have a nice day.\n \n 635\n 01:11:33.510 --> 01:11:34.150\n Dexter Horthy: Okay.\n \n 636\n 01:11:36.336 --> 01:11:42.150\n Vaibhav Gupta: And then we'll do the last one really fast. While we're out here, and let's while while visa is loading.\n \n 637\n 01:11:43.540 --> 01:11:47.350\n Vaibhav Gupta: I hate this. I. This is the part I hate the most about. V. 0, it takes so long.\n \n 638\n 01:11:49.120 --> 01:11:50.050\n Vaibhav Gupta: Okay, well.\n \n 639\n 01:11:50.050 --> 01:11:52.090\n Dexter Horthy: Lot of deterministic code.\n \n 640\n 01:11:53.280 --> 01:11:57.890\n Vaibhav Gupta: You are tasked with a video editing plan. Okay, I'm gonna.\n \n 641\n 01:11:57.890 --> 01:11:58.560\n Dexter Horthy: Sick.\n \n 642\n 01:11:59.180 --> 01:12:05.699\n Vaibhav Gupta: Okay, I'm just gonna go do this alright. So right over here. By the way, we can see this.\n \n 643\n 01:12:06.730 --> 01:12:15.569\n Vaibhav Gupta: So now it has a fun, little ui for me to go. Do build this in not not to edit, just to view the final outcome.\n \n 644\n 01:12:16.460 --> 01:12:17.170\n Vaibhav Gupta: Oh.\n \n 645\n 01:12:21.990 --> 01:12:26.050\n Dexter Horthy: Oh, do you find the frowny face makes Vercel make better content.\n \n 646\n 01:12:26.220 --> 01:12:28.779\n Vaibhav Gupta: No, I was just annoyed that it did the wrong thing.\n \n 647\n 01:12:30.070 --> 01:12:30.770\n Vaibhav Gupta: Video.\n \n 648\n 01:12:30.770 --> 01:12:33.749\n Dexter Horthy: Well, maybe if you went and read your prompt.\n \n 649\n 01:12:35.320 --> 01:12:39.409\n Vaibhav Gupta: That. Well, I can't read the V 0 prompt. So it's a little bit harder.\n \n 650\n 01:12:40.351 --> 01:12:46.129\n Vaibhav Gupta: Insert script expert here. What is this trying to do. Do you have your? Do you have your data models and everything else on here?\n \n 651\n 01:12:48.160 --> 01:13:01.359\n Vaibhav Gupta: If you don't, then I I can try. But it's harder to do without like actual function types, because this prompt is a little bit more complex. But let me just give you some general guidelines that I see right off this right off my top right off the top of my head\n \n 652\n 01:13:01.780 --> 01:13:06.779\n Vaibhav Gupta: when I read this from the 1st thing that I see is.\n \n 653\n 01:13:07.220 --> 01:13:11.779\n Vaibhav Gupta: I don't actually think you need all this data like this is a lot more redundant.\n \n 654\n 01:13:12.000 --> 01:13:26.370\n Vaibhav Gupta: You're I'm not sure if this is all a system prompt or a user prompt. But when I go look at this, the 1st thing that I see is that this is not it's like mixing and matching both the content and the instructions all over the place.\n \n 655\n 01:13:26.580 --> 01:13:34.229\n Vaibhav Gupta: because, like you're listing out your, you have instructions, content instructions, content, instructions.\n \n 656\n 01:13:35.070 --> 01:13:38.270\n Vaibhav Gupta: instructions. It looks like more content.\n \n 657\n 01:13:38.580 --> 01:13:40.580\n Dexter Horthy: Oh, that's this is the output schema.\n \n 658\n 01:13:40.580 --> 01:13:43.810\n Vaibhav Gupta: Oh, this is the output format. Yeah, so it looks like you're.\n \n 659\n 01:13:43.810 --> 01:13:45.370\n Dexter Horthy: But then there's more instructions.\n \n 660\n 01:13:45.370 --> 01:13:49.120\n Vaibhav Gupta: Yeah, it just feels like you're we're mixing a lot of instructions, and it doesn't read\n \n 661\n 01:13:49.685 --> 01:13:53.270\n Vaibhav Gupta: in the way that I would write this if I were a human.\n \n 662\n 01:13:53.470 --> 01:14:10.579\n Vaibhav Gupta: And we're also writing a lot of things that's like you are a blah blah blah like the model doesn't care who it is, it just has to know the job it wants to do. You don't need to tell it. This is my role. If you notice in any of the prompts. I didn't. I didn't like. I wasn't like you're a senior engineer that does blah blah blah. I just like write the code from this prompt.\n \n 663\n 01:14:11.170 --> 01:14:13.719\n Vaibhav Gupta: That's like the 1st thing I would do. So let's just like.\n \n 664\n 01:14:14.090 --> 01:14:19.030\n Vaibhav Gupta: there you go. And, by the way, for people generating this, now, you can generate this kind of ui automatically from here.\n \n 665\n 01:14:19.380 --> 01:14:32.990\n Vaibhav Gupta: and this would be super super easy for me to go coach, and then I could put buttons on here that I'll call like Enrich, which calls another Lm function that finds all the data about that company using like a research thing that I go built. Sorry I context which really fast.\n \n 666\n 01:14:35.130 --> 01:14:42.379\n Vaibhav Gupta: But let me go back really fast and start a new chat thing make this prompt better.\n \n 667\n 01:14:42.770 --> 01:14:50.440\n Vaibhav Gupta: No. Xml and the error rendering Markdown is the thing that hopefully we'll fix in.\n \n 668\n 01:14:51.050 --> 01:15:09.330\n Dexter Horthy: Yeah, prashant the the ura. We were just talking about this before the episode that, like asking models to adopt a role is, I think the best prompt engineers out there have been talking for months about, if not longer, about how that doesn't really work very well or like. It doesn't have that much effect on the output.\n \n 669\n 01:15:09.770 --> 01:15:17.339\n sahil: The funny thing is that this comes right out of Claude from generation as well.\n \n 670\n 01:15:19.330 --> 01:15:20.949\n Vaibhav Gupta: I bet this is my.\n \n 671\n 01:15:20.950 --> 01:15:25.029\n Dexter Horthy: Because there's a lot of data in the training set doesn't mean it's correct or good data.\n \n 672\n 01:15:25.480 --> 01:15:29.839\n Vaibhav Gupta: Yeah, just like the most code out there is kind of shit you probably shouldn't follow most code.\n \n 673\n 01:15:31.045 --> 01:15:31.600\n Vaibhav Gupta: But\n \n 674\n 01:15:33.300 --> 01:15:40.390\n Vaibhav Gupta: a lot of code is still very good, and you should follow that. But it's all about finding the right segments. So in this case the 1st thing I do is like, get rid of this.\n \n 675\n 01:15:42.480 --> 01:15:50.800\n Vaibhav Gupta: create a segmentation plan for the following trip. Breaking logic for each segment, ensure it contains complete thought or idea. Estimate a reasonable time. Consider the pacing\n \n 676\n 01:15:51.445 --> 01:15:55.130\n Vaibhav Gupta: and it's important to kind of like, describe what these mean\n \n 677\n 01:15:55.540 --> 01:16:04.009\n Vaibhav Gupta: cause it probably doesn't actually know. And I I have no idea what it actually means for fast, slower medium like, I'm just it just made stuff up. You need to go and actually understand your own.\n \n 678\n 01:16:04.550 --> 01:16:07.780\n Vaibhav Gupta: I think, for that and like, if you.\n \n 679\n 01:16:07.780 --> 01:16:19.930\n Dexter Horthy: Or you could even force it in the schema. Right? You could be like, Okay, cool. I know how long this is, and I can say. I know I want exactly, you know. Do it in code, and say, I want exactly 40 cuts, because I want 30 to 40 cuts versus something else.\n \n 680\n 01:16:20.400 --> 01:16:22.510\n Vaibhav Gupta: I want a.\n \n 681\n 01:16:23.390 --> 01:16:25.750\n Dexter Horthy: Because then we're not making the model count.\n \n 682\n 01:16:35.280 --> 01:16:35.870\n Dexter Horthy: There you go.\n \n 683\n 01:16:35.870 --> 01:16:38.499\n Vaibhav Gupta: And instead of actually outputting all the stuff.\n \n 684\n 01:16:39.240 --> 01:16:42.119\n Vaibhav Gupta: I will actually just literally tell the model to go. Do this.\n \n 685\n 01:16:42.230 --> 01:16:50.589\n Vaibhav Gupta: I will literally tell it exactly what I want the pacing to be. Instead of describing all the pacings, I will specifically only admit the pacing that's actually relevant to the model.\n \n 686\n 01:16:50.880 --> 01:17:00.549\n Dexter Horthy: And that's the same thing, the user and the program. See a single world fast. But then you translate that into more verbose instructions, but only the Llm. Sees that part.\n \n 687\n 01:17:00.740 --> 01:17:07.150\n Vaibhav Gupta: And the Lm. Is not seeing everything else. So if I change this from slow to fast, it sees this one, whereas in this one it sees slow.\n \n 688\n 01:17:08.820 --> 01:17:12.369\n Vaibhav Gupta: right? So now it's able to actually go. Do this along the way.\n \n 689\n 01:17:13.204 --> 01:17:14.859\n Vaibhav Gupta: And now, when I.\n \n 690\n 01:17:14.860 --> 01:17:15.769\n Dexter Horthy: You can run it.\n \n 691\n 01:17:16.060 --> 01:17:17.540\n Vaibhav Gupta: Why not? Yeah? Why not?\n \n 692\n 01:17:21.090 --> 01:17:25.060\n Vaibhav Gupta: And I don't even know what transition is like. If transitions have a separate cut\n \n 693\n 01:17:25.670 --> 01:17:27.390\n Vaibhav Gupta: like, sure, let's do that.\n \n 694\n 01:17:28.520 --> 01:17:30.670\n Vaibhav Gupta: Let's let's just run this way.\n \n 695\n 01:17:33.390 --> 01:17:38.660\n Vaibhav Gupta: and it's able to go do this. Now. Duration is kind of is kind of misleading, and the description is kind of\n \n 696\n 01:17:40.470 --> 01:17:42.000\n Vaibhav Gupta: 30 seconds.\n \n 697\n 01:17:42.460 --> 01:17:43.770\n Vaibhav Gupta: I'm gonna change this.\n \n 698\n 01:17:46.690 --> 01:17:47.680\n Vaibhav Gupta: Alias.\n \n 699\n 01:17:53.430 --> 01:17:59.470\n sahil: I don't think we need duration, because the duration is essentially the content, so we can skip it.\n \n 700\n 01:17:59.470 --> 01:18:07.730\n Vaibhav Gupta: Yes, but you might benefit from actually having a duration in there, just so that a model can like plan\n \n 701\n 01:18:08.080 --> 01:18:09.260\n Vaibhav Gupta: for each segment.\n \n 702\n 01:18:09.870 --> 01:18:11.839\n Vaibhav Gupta: It's the same thing. It's like.\n \n 703\n 01:18:11.840 --> 01:18:13.189\n Dexter Horthy: Duration. Kind of Right.\n \n 704\n 01:18:13.490 --> 01:18:29.010\n Vaibhav Gupta: Cause you have. You have a thing in there where you're thinking about prompting, but you want the model to also be thinking about duration like the amount of inference it has. It's about the amount caches. Why do we have a Redis cache? Not because we can't go to the database because we don't want to go to the database all the time.\n \n 705\n 01:18:29.180 --> 01:18:33.159\n Vaibhav Gupta: Why are you putting duration here? The model can just like kind of think about this.\n \n 706\n 01:18:33.550 --> 01:18:37.769\n Vaibhav Gupta: Now we see that this content is like pretty short form.\n \n 707\n 01:18:37.940 --> 01:18:41.000\n Vaibhav Gupta: which is totally fine. But if you want this to be the full content.\n \n 708\n 01:18:41.280 --> 01:18:42.700\n Vaibhav Gupta: then we can just do this.\n \n 709\n 01:18:43.270 --> 01:18:47.150\n Vaibhav Gupta: We can. We can guide the model to generate more text, use.\n \n 710\n 01:18:47.150 --> 01:18:58.189\n Dexter Horthy: I think your input test case is really is really small. I think this is actually the right, the right text straight from the input. Thing. So like, we need like a way longer script to really test this. Anyways.\n \n 711\n 01:18:58.830 --> 01:19:00.909\n sahil: Can I drop in a can I drop in a script?\n \n 712\n 01:19:01.020 --> 01:19:01.660\n sahil: I have one.\n \n 713\n 01:19:01.660 --> 01:19:02.510\n Vaibhav Gupta: Yeah, dropping us.\n \n 714\n 01:19:02.510 --> 01:19:03.679\n Dexter Horthy: Yes, that's a script.\n \n 715\n 01:19:05.410 --> 01:19:06.540\n Dexter Horthy: Fuck. Yeah.\n \n 716\n 01:19:07.240 --> 01:19:09.100\n Dexter Horthy: On the fucking. AI that works.\n \n 717\n 01:19:09.100 --> 01:19:09.749\n sahil: There you go.\n \n 718\n 01:19:10.660 --> 01:19:12.140\n sahil: History of computing.\n \n 719\n 01:19:13.610 --> 01:19:19.080\n Dexter Horthy: I like this, we should do this more. We should. We should take people's real problems and solve them.\n \n 720\n 01:19:19.820 --> 01:19:20.699\n Vaibhav Gupta: Let's run it\n \n 721\n 01:19:26.020 --> 01:19:26.840\n Vaibhav Gupta: right?\n \n 722\n 01:19:28.080 --> 01:19:29.819\n Vaibhav Gupta: So you can actually see what it did.\n \n 723\n 01:19:30.040 --> 01:19:32.799\n Vaibhav Gupta: It actually spit out all the content as a line.\n \n 724\n 01:19:34.500 --> 01:19:37.689\n sahil: But the duration seconds is 60 for everything now.\n \n 725\n 01:19:37.750 --> 01:19:41.309\n Dexter Horthy: Do you still want it to be a list by Bob? Or do you want to just be a single strength.\n \n 726\n 01:19:42.059 --> 01:19:47.280\n Vaibhav Gupta: We can. Oh, sorry, yes, estimated\n \n 727\n 01:19:48.780 --> 01:19:54.030\n Vaibhav Gupta: seconds. Let's give it some description like, what? How? How do you estimate duration?\n \n 728\n 01:19:57.253 --> 01:20:04.980\n sahil: Let's say every 1,000 characters is a minute or 60 seconds, or.\n \n 729\n 01:20:05.850 --> 01:20:08.709\n Dexter Horthy: Oh, are we gonna make the model count characters.\n \n 730\n 01:20:09.870 --> 01:20:12.009\n Vaibhav Gupta: Every like. Let's let's try this. I want that.\n \n 731\n 01:20:12.010 --> 01:20:18.490\n sahil: Every every so typically every 1 20 boats per minute. So\n \n 732\n 01:20:19.027 --> 01:20:22.399\n sahil: there you can count words or characters. I don't know.\n \n 733\n 01:20:23.200 --> 01:20:26.850\n Vaibhav Gupta: Words per minute, what is average\n \n 734\n 01:20:28.870 --> 01:20:31.249\n Vaibhav Gupta: right? And we might actually find that like, hey.\n \n 735\n 01:20:31.370 --> 01:20:36.399\n Vaibhav Gupta: if we do this, it's actually when we do slower pacing. It's gonna be a little bit. It's about a hundred words per minute.\n \n 736\n 01:20:38.120 --> 01:20:43.840\n Vaibhav Gupta: If we do this, it's gonna be like a hundred 20, and we do fast. It's gonna be like a hundred 50.\n \n 737\n 01:20:44.490 --> 01:20:53.829\n Vaibhav Gupta: So you might actually like find that it's useful to actually guide the model appropriately for the different use cases, because that's what I would do. I would I would have a slightly talk faster voice in general, not just like the pacing.\n \n 738\n 01:20:57.480 --> 01:21:03.769\n Dexter Horthy: It would be interesting to also have this like start suggesting like, Hey, what do you want to show on the screen during this cut? Right.\n \n 739\n 01:21:04.360 --> 01:21:05.900\n Vaibhav Gupta: Exactly so now.\n \n 740\n 01:21:05.900 --> 01:21:08.140\n Dexter Horthy: Do like a image, search and pull that in.\n \n 741\n 01:21:08.530 --> 01:21:11.119\n Vaibhav Gupta: Background image. So let's do that.\n \n 742\n 01:21:12.690 --> 01:21:21.849\n Dexter Horthy: This would be a fun building, like an example of this end to end of like, how to just like generate automated video content from little scripts, an end to end content. Pipeline.\n \n 743\n 01:21:23.560 --> 01:21:26.769\n sahil: To make you can come, help me build my my company.\n \n 744\n 01:21:27.440 --> 01:21:31.762\n Dexter Horthy: I was gonna say, yeah, we have to be careful not to build a open source competitor to sail.\n \n 745\n 01:21:31.990 --> 01:21:34.540\n sahil: I would love for that.\n \n 746\n 01:21:37.995 --> 01:21:44.529\n Vaibhav Gupta: a description description, that is, that is.\n \n 747\n 01:21:44.760 --> 01:22:00.249\n sahil: So I have a couple of questions over here. So earlier in the example you were, you were showing how we can create indexes, and to to make sure that we are not spitting out so much text and saving tokens. I know, like, obviously, this is slightly\n \n 748\n 01:22:01.110 --> 01:22:06.819\n sahil: different case where we have to spit out the text. Are there any tips or tricks we could use to\n \n 749\n 01:22:08.050 --> 01:22:12.209\n sahil: do that index thing in here in any way, shape or form?\n \n 750\n 01:22:12.850 --> 01:22:21.669\n Vaibhav Gupta: Well, I don't actually know if you have to spit out the text and form like, honestly, you could just make this a lookup table based on strings like you just spit out every line, every sentence into itself.\n \n 751\n 01:22:22.560 --> 01:22:25.640\n Vaibhav Gupta: As like a thing, and then you could have the model spit out like a span.\n \n 752\n 01:22:26.700 --> 01:22:33.580\n Vaibhav Gupta: so like from dialogue, one to dialog. 7. Do this dialogue one to 3, and they'll naturally find breakpoints\n \n 753\n 01:22:34.040 --> 01:22:52.539\n Vaibhav Gupta: in the dialog. And now you can go. Do that. You can ask. You can build a separate pipeline that says, if you really care about like cost and latency, I would build a separate pipeline that says, Given all these dialogues, what is the most intuitive breakpoints to inject into here, and then you go get, generate the background, image and everything off of that.\n \n 754\n 01:22:53.260 --> 01:22:59.359\n Vaibhav Gupta: So you can solve this problem in many different ways, but it's more about identifying the indexes of where the breakpoint should be, for where transition should happen.\n \n 755\n 01:23:00.290 --> 01:23:10.490\n Dexter Horthy: Oh, so it becomes similar to kind of almost the diarization where maybe you just wanted to output like the first, st like the the biggest, like the smallest unique chunk that like offsets the text. There.\n \n 756\n 01:23:10.860 --> 01:23:13.059\n Vaibhav Gupta: Exactly cool. Exactly. Where would you go?\n \n 757\n 01:23:15.150 --> 01:23:15.690\n Dexter Horthy: Cool.\n \n 758\n 01:23:15.690 --> 01:23:27.579\n Dexter Horthy: We're 90 min, we should probably wrap it up. This was super fun. Y'all. Thank you so much by Bob for sharing your prompting wisdom for those of you who made it to the very end. Congrats.

Create Google Cloud Project\n1. Go to [Google Cloud Console](https://console.cloud.google.com/)\n2. Click \"New Project\" or use the project selector\n3. Name: `ai-content-pipeline`\n4. Click \"Create\"\n\n### 2. Enable YouTube Data API\n1. In the Google Cloud Console, go to \"APIs & Services\" → \"Library\"\n2. Search for \"YouTube Data API v3\"\n3. Click on it and press \"Enable\"\n\n### 3. Create OAuth 2.0 Credentials\n1. Go to \"APIs & Services\" → \"Credentials\"\n2. Click \"Create Credentials\" → \"OAuth 2.0 Client ID\"\n3. If prompted, configure OAuth consent screen first:\n - Choose \"External\" for user type\n - Fill in required fields:\n - App name: `AI Content Pipeline`\n - User support email: your email\n - Developer contact: your email\n - Add scopes: `https://www.googleapis.com/auth/youtube.upload`\n - Add test users if needed\n4. Create OAuth 2.0 Client ID:\n - Application type: \"Desktop application\"\n - Name: `AI Content Pipeline Desktop`\n - Click \"Create\"\n\n### 4. Download Credentials\n1. Click the download button next to your newly created OAuth client\n2. Save the JSON file as `google_credentials.json` in your backend directory\n3. **NEVER commit this file to version control**\n\n### 5. Required Scopes\n- `https://www.googleapis.com/auth/youtube.upload` - Upload videos\n- `https://www.googleapis.com/auth/youtube.readonly` - Read channel info\n\n## Zoom API Setup\n\n### 1. Create Zoom App\n1. Go to [Zoom Marketplace](https://marketplace.zoom.us/)\n2. Sign in with your Zoom account\n3. Click \"Develop\" → \"Build App\"\n4. Choose \"Server-to-Server OAuth\" app type\n5. Fill in app details:\n - App name: `AI Content Pipeline`\n - Company name: Your company\n - Developer contact: your email\n\n### 2. Get API Credentials\n1. Go to your app's \"App Credentials\" page\n2. Copy the following:\n - **Account ID**: Your Zoom account ID\n - **Client ID**: Your app's client ID\n - **Client Secret**: Your app's client secret\n3. Add required scopes:\n - `meeting:read` - Read meeting details\n - `recording:read` - Access recordings\n\n### 3. Environment Variables Setup\n```bash\n# Add to backend/.env\nZOOM_ACCOUNT_ID=your_account_id_here\nZOOM_CLIENT_ID=your_client_id_here\nZOOM_CLIENT_SECRET=your_client_secret_here\n```\n\n## OAuth Token Generation\n\nUse the provided OAuth setup script to generate initial tokens:\n\n```bash\ncd backend\nuv run python oauth_setup.py\n```\n\nThis will:\n1. Generate Google OAuth tokens for YouTube API access\n2. Test Zoom API connection\n3. Save tokens securely for backend use\n\n## Security Best Practices\n\n### Google Credentials\n- Store `google_credentials.json` outside of version control\n- Use environment variables for sensitive data\n- Rotate credentials regularly\n- Use service accounts for production\n\n### Zoom Credentials\n- Never expose client secrets in frontend code\n- Use server-to-server OAuth for backend operations\n- Store tokens securely with proper encryption\n- Implement token refresh logic\n\n## Troubleshooting\n\n### Google OAuth Issues\n- **Invalid client**: Verify credentials file path\n- **Access denied**: Check OAuth consent screen configuration\n- **Quota exceeded**: Monitor API usage in Google Cloud Console\n\n### Zoom API Issues\n- **Invalid credentials**: Verify Account ID, Client ID, and Client Secret\n- **Insufficient permissions**: Check app scopes in Zoom Marketplace\n- **Rate limiting**: Implement proper backoff strategies\n\n## Testing OAuth Setup\n\n```bash\n# Test Google OAuth\ncd backend\nuv run python -c \"from oauth_setup import test_google_auth; test_google_auth()\"\n\n# Test Zoom API\ncd backend \nuv run python -c \"from oauth_setup import test_zoom_auth; test_zoom_auth()\"\n```" }, { "path": "2025-06-24-ai-content-pipeline/frontend/.gitignore", "content": "# See https://help.github.com/articles/ignoring-files/ for more about ignoring files.\n\n# dependencies\n/node_modules\n/.pnp\n.pnp.*\n.yarn/*\n!.yarn/patches\n!.yarn/plugins\n!.yarn/releases\n!.yarn/versions\n\n# testing\n/coverage\n\n# next.js\n/.next/\n/out/\n\n# production\n/build\n\n# misc\n.DS_Store\n*.pem\n\n# debug\nnpm-debug.log*\nyarn-debug.log*\nyarn-error.log*\n.pnpm-debug.log*\n\n# env files (can opt-in for committing if needed)\n.env*\n\n# vercel\n.vercel\n\n# typescript\n*.tsbuildinfo\nnext-env.d.ts\n" }, { "path": "2025-06-24-ai-content-pipeline/frontend/README.md", "content": "This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).\n\n## Getting Started\n\nFirst, run the development server:\n\n```bash\nnpm run dev\n# or\nyarn dev\n# or\npnpm dev\n# or\nbun dev\n```\n\nOpen [http://localhost:3000](http://localhost:3000) with your browser to see the result.\n\nYou can start editing the page by modifying `app/page.tsx`.
