You represent that if you do not own copyright in the code that you have the authority to submit it under the [Project's license](./LICENSE.md). All feedback, suggestions, or contributions are not confidential.

The Project abides by the Organization's [code of conduct](https://github.com/guidance-ai/governance/blob/main/CODE-OF-CONDUCT.md) and [trademark policy](https://github.com/guidance-ai/governance/blob/main/TRADEMARKS.md).

# Development Notes

We welcome contributions to `guidance`, and this document exists to provide useful information contributors.

## Developer Setup

Start by creating a fresh environment with something similar to:
```bash
conda create --name guidancedev python=3.12
conda activate guidancedev
```

Install guidance (without CUDA):
```bash
python -m pip install -e .[all,test,llamacpp,transformers]
```

Alternatively, install guidance with CUDA support. There are various ways to do this. We recommend:
```bash
conda install pytorch pytorch-cuda=12.1 -c pytorch -c nvidia
CMAKE_ARGS="-DGGML_CUDA=on" python -m pip install -e .[all,test,llamacpp,transformers]
```

## Running Tests

To run a basic test suite locally:
```bash
python -m pytest ./tests/
```
which runs our basic test suite.
Where an LLM is required, this will default to using GPT2 on the CPU.

To change that default, run
```bash
python -m pytest --selected_model <MODELNAME> ./tests/
```
where `<MODELNAME>` is taken from one of the selected_model_name options defined in `./tests/conftest.py`.

Alternatively, the default value for `--selected_model` can be set via the `GUIDANCE_SELECTED_MODEL` environment variable.
This may be useful when trying to use a debugger when running `pytest`, and setting the extra command line argument in the debugger configuration is tricky.
Just remember that the environment variable needs to be set _before_ starting PyCharm/VSCode etc.

## Adding LLMs to the test matrix

Our tests run on a variety of LLMs.
These fall into three categories: CPU-based, GPU-based and endpoint-based (which need credentials).

### New CPU or GPU-based models

Due to the limited resources of the regular GitHub runner machines, the LLM under test is a dimension of our test matrix (otherwise the GitHub runners will tend to run out of RAM and/or hard drive space).
New models should be configured in `conftest.py`.
The model will then be available via the `selected_model` fixture for all tests.
If you have a test which should only run for particular models, you can use the `selected_model_name` fixture to check, and call `pytest.skip()` if necessary.
An example of this is given in `test_llama_cpp.py`.

### New endpoint based models

If your model requires credentials, then those will need to be added to our GitHub repository as secrets.
The endpoint itself (and any other required information) should be configured as environment variables too.
When the test runs, the environment variables will be set, and can then be used to configure the model as required.
See `test_azureai_openai.py` for examples of this being done.

## Formatting & Linting

We use `ruff` to format our codebase.
To install the correct version, run `pip install -e .[dev]`.
You can then run `ruff format /path/to/modified/file.py` to format the code.
The path can also be an entire directory, or omitted entirely to format all files beneath the current directory.
There are (rare) cases where manual formatting is preferable; for these [`ruff` provides pragmas for suppression](https://docs.astral.sh/ruff/formatter/#format-suppression).
To sort imports, use `ruff check --select I /path/to/modified/file.py --fix`.
These commands are run (but not enforced *yet*) in the build.

**Guidance is an efficient programming paradigm for steering language models.** With Guidance, you can control how output is structured and get high-quality output for your use case—*while reducing latency and cost vs. conventional prompting or fine-tuning.* It allows users to constrain generation (e.g. with regex and CFGs) as well as to interleave control (conditionals, loops, tool use) and generation seamlessly.

   * [Install](#install)
   * [Features](#features)


## Install
Guidance is available through PyPI and supports a variety of backends (Transformers, llama.cpp, OpenAI, etc.).
If you already have the backend required for your model, you can simply run
```bash
pip install guidance
```

## Features

### A Pythonic interface for language models

When using Guidance, you can work with large language models using common Python idioms:

```python
from guidance import system, user, assistant, gen
from guidance.models import Transformers

# Could also do LlamaCpp or many other models
phi_lm = Transformers("microsoft/Phi-4-mini-instruct")

# Model objects are immutable, so this is a copy
lm = phi_lm

with system():
    lm += "You are a helpful assistant"

with user():
    lm += "Hello. What is your name?"

with assistant():
    lm += gen(max_tokens=20)

print(lm)
```
If run at the command line, this will produce output like:
```
<|system|>You are a helpful assistant<|end|><|user|>Hello. What is your name?<|end|><|assistant|>I am Phi, an AI developed by Microsoft. How can I help you today?
```
However, if running in a Jupyter notebook, then Guidance provides a widget for a richer user experience:

<img src="docs/figures/widget_basic_example_20250703.png" alt="Guidance widget showing HTML generation" />

With Guidance, it's really easy to capture generated text:

```python
# Get a new copy of the Model
lm = phi_lm

with system():
    lm += "You are a helpful assistant"

with user():
    lm += "Hello. What is your name?"

with assistant():
    lm += gen(name="lm_response", max_tokens=20)

print(f"{lm['lm_response']=}")
```

```
lm['lm_response']='I am Phi, an AI developed by Microsoft. How can I help you today?'
```

### Guarantee output syntax with constrained generation

Guidance provides an easy to use, yet immensely powerful syntax for constraining the output of a language model.
For example, a `gen()` call can be constrained to match a regular expression:

```python
lm = phi_lm

with system():
    lm += "You are a teenager"

with user():
    lm += "How old are you?"

with assistant():
    lm += gen("lm_age", regex=r"\d+", temperature=0.8)

print(f"The language model is {lm['lm_age']} years old")
```

```
The language model is 13 years old
```

Often, we know that the output has to be an item from a list we know in advance.
Guidance provides a `select()` function for this scenario:

```python
from guidance import select

lm = phi_lm

with system():
    lm += "You are a geography expert"

with user():
    lm += """What is the capital of Sweden? Answer with the correct letter.

    A) Helsinki
    B) Reykjavík 
    C) Stockholm
    D) Oslo
    """

with assistant():
    lm += select(["A", "B", "C", "D"], name="model_selection")

print(f"The model selected {lm['model_selection']}")
```

```
The model selected C
```

The constraint system offered by Guidance is extremely powerful.
It can ensure that the output conforms to any context free grammar (so long as the backend LLM has full support for Guidance).
More on this below.

### Debug grammars offline (no model API calls)

When iterating on constraints, you can validate candidate strings locally and test a full run with the `Mock` model.

```python
from guidance import gen
from guidance.models import Mock

grammar = "expr=" + gen(regex=r"\d+([+*]\d+)*", name="expr")

# 1) Validate strings directly against the grammar
assert grammar.match("expr=12+7*3") is not None
assert grammar.match("expr=12+*3") is None

# 2) Run the same grammar with a local mock model
lm = Mock(b"<s>expr=12+7*3")
lm += grammar
print(lm["expr"])  # 12+7*3
```

### Create your own Guidance functions

With Guidance, you can create your own Guidance functions which can interact with language models.
These are marked using the `@guidance` decorator.
Suppose we wanted to answer lots of multiple choice questions.
We could do something like the following:

```python
import guidance

from guidance.models import Model

ASCII_OFFSET = ord("a")

@guidance
def zero_shot_multiple_choice(
    language_model: Model,
    question: str,
    choices: list[str],
):
    with user():
        language_model += question + "\n"
        for i, choice in enumerate(choices):
            language_model += f"{chr(i+ASCII_OFFSET)} : {choice}\n"

    with assistant():
        language_model += select(
            [chr(i + ASCII_OFFSET) for i in range(len(choices))], name="string_choice"
        )

    return language_model
```
Now, define some questions:
```python
questions = [

We can use our decorated function like `gen()` or `select()`.
The `language_model` argument will be filled in for us automatically:
```python
lm = phi_lm

with system():
    lm += "You are a student taking a multiple choice test."

for mcq in questions:
    lm_temp = lm + zero_shot_multiple_choice(question=mcq["question"], choices=mcq["choices"])
    converted_answer = ord(lm_temp["string_choice"]) - ASCII_OFFSET
    print(lm_temp)
    print(f"LM Answer: {converted_answer},  Correct Answer: {mcq['answer']}")
```

Guidance functions can be composed, in order to construct a full context free grammar.
For example, we can create Guidance functions to build a simple HTML webpage (note that this is _not_ a full implementation of HTML).
We start with a simple function which will generate text which does not contain any HTML tags.
The function is marked as `stateless` to indicate that we intend to use it for composing a grammar:

```python
@guidance(stateless=True)
def _gen_text(lm: Model):
    return lm + gen(regex="[^<>]+") 
```

We can then use this function to generate text within an arbitrary HTML tag:
```python
@guidance(stateless=True)
def _gen_text_in_tag(lm: Model, tag: str):
    lm += f"<{tag}>"
    lm += _gen_text()
    lm += f"</{tag}>"
    return lm
```
Now, let us create the page header. As part of this, we need to generate a page title:
```python
@guidance(stateless=True)
def _gen_header(lm: Model):
    lm += "<head>\n"
    lm += _gen_text_in_tag("title") + "\n"
    lm += "</head>\n"
    return lm
```
The body of the HTML page is going to be filled with headings and paragraphs.
We can define a function to do each:
```python
from guidance.library import one_or_more

@guidance(stateless=True)
def _gen_heading(lm: Model):
    lm += select(
        options=[_gen_text_in_tag("h1"), _gen_text_in_tag("h2"), _gen_text_in_tag("h3")]
    )
    lm += "\n"
    return lm

@guidance(stateless=True)
def _gen_para(lm: Model):
    lm += "<p>"
    lm += one_or_more(
        select(
            options=[
                _gen_text(),
                _gen_text_in_tag("em"),
                _gen_text_in_tag("strong"),
                "<br />",
            ],
        )
    )
    lm += "</p>\n"
    return lm
```
Now, the function to define the body of the HTML itself:
```python
@guidance(stateless=True)
def _gen_body(lm: Model):
    lm += "<body>\n"
    lm += one_or_more(select(options=[_gen_heading(), one_or_more(_gen_para())]))
    lm += "</body>\n"
    return lm
```
Next, we come to the function which generates the complete HTML page.
We add the HTML start tag, then generate the header, then body, and then append the ending HTML tag:
```python
@guidance(stateless=True)
def _gen_html(lm: Model):
    lm += "<html>\n"
    lm += _gen_header()
    lm += _gen_body()
    lm += "</html>\n"
    return lm
```
Finally, we provide a user-friendly wrapper, which will allow us to:
- Set the temperature of the generation
- Capture the generated page from the Model object
```python
from guidance.library import capture, with_temperature

@guidance(stateless=True)
def make_html(
    lm,
    name: str | None = None,
    *,
    temperature: float = 0.0,
):
    return lm + capture(
        with_temperature(_gen_html(), temperature=temperature),
        name=name,
    )
```
Now, use this to generate a simple webpage:
```python
lm = phi_lm

with system():
    lm += "You are an expert in HTML"

with user():
    lm += "Create a simple and short web page about your life story."

with assistant():
    lm += make_html(name="html_text", temperature=0.7)
```

When running in a Jupyter Notebook so that the widget is active, we get the following output:

<img src="docs/figures/widget_make_html_20250703.png" alt="Guidance widget showing HTML generation with token fast-forwarding" />

Note the varying highlighting of the generation.
This is showing another of Guidance's capabilities: fast-forwarding of tokens.
The constraints imposed by a grammar often mean that some tokens are known in advance.
Guidance doesn't need the model to generate these; instead it can insert them into the generation.
This saves forward passes through the model, and hence reduces GPU usage.
For example, in the above HTML generation, Guidance always knows the last opening tag.
If the last opened tag was `<h1>` (for example), then as soon as the model generates `</`, Guidance can fill in `h1>` without needing the model to perform a forward pass.

### Generating JSON

A JSON schema is actually a context free grammar, and hence it can be used to constrain an LLM using Guidance.
This is a common enough case that Guidance provides special support for it.
A quick sample, based on a Pydantic model:
```python
import json
from pydantic import BaseModel, Field

from guidance import json as gen_json

class BloodPressure(BaseModel):
    systolic: int = Field(gt=300, le=400)
    diastolic: int = Field(gt=0, le=20)
    location: str = Field(max_length=50)
    model_config = dict(extra="forbid")

lm = phi_lm

with system():
    lm += "You are a doctor taking a patient's blood pressure taken from their arm"

with user():
    lm += "Report the blood pressure"

with assistant():
    lm += gen_json(name="bp", schema=BloodPressure)

print(f"{lm['bp']=}")

# Use Python's JSON library
loaded_json = json.loads(lm["bp"])
print(json.dumps(loaded_json, indent=4))

# Use Pydantic
result = BloodPressure.model_validate_json(lm["bp"])
print(result.model_dump_json(indent=8))
```
```
lm['bp']='{"systolic": 301, "diastolic": 15, "location": "arm"}'
{
    "systolic": 301,
    "diastolic": 15,
    "location": "arm"
}
{
        "systolic": 301,
        "diastolic": 15,
        "location": "arm"
}
```
Note that the generated blood pressure is not one the model will have seen for a human.
When generating JSON, a substantial number of tokens can often be fast-forwarded, due to the structural constraints imposed by the schema.

**Guidance** enables you to control modern language models more effectively and efficiently than traditional prompting or chaining. Guidance programs allow you to interleave generation, prompting, and logical control into a single continuous flow matching how the language model actually processes the text.

Install
=======

Guidance can be installed from `PyPI <https://pypi.org/project/guidance>`_::

   pip install guidance

        >>> lm += gen("my_generation", max_tokens=10)
        >>> print(lm["my_generation"])
        some text from the LLM

    Parameters
    ----------

        name : str or None
            If this is not None then the the results of the generation will be saved as a variable on
            the Model object (so you can access the result as `lm["var_name"]`).

        max_tokens : int
            The maximum number of generation tokens we should use. Note that this limit is not exact when
            regular expression pattern constraints are present, but guidance does attempt to end the generation
            as soon as possible while keeping the regex constraints satisfied.

        list_append : bool
            If this is True then the results saved to `lm[name]` will not be written directly but rather appended
            to a list (if no list with the current name is present one will be created). This is useful for
            building lists inside python loops.

        regex : str or None
            This is a regular expression that will be used to constrain the generation. The model is only allowed
            to generate tokens that match this regular expression. Note that for variable length expressions the
            model is free to continue the expression after a complete match, but generation will terminate as soon
            as the model generates anything that does not match the pattern (this ending behavior may change a bit we
            update guidance to maintain the grammar parsing state between calls).

        stop : str or list or None
            The stop string (or list of strings) we should use for terminating this generation segment.

        stop_regex : str or list or None
            The stop regular expression (or list of regular expressions) we should use for terminating this generation segment.

        save_stop_text : bool or str
            If True then this saves the captured stop text or regex into a variable of the name `str(name) + "_stop_text"`. If
            a string is given then the captured stop text is saved under that name.

        temperature : float
            The temperature to use during this generation call. Note that when parsing ambiguous grammars that include
            multiple conflicting temperatures (for example from multiple possible `gen` calls inside a `select`) the highest
            temperature of all options is used by the model (since we only want to run the model once, not once for every
            possible parse path).

        top_p : float
            TODO! Will control the models top_p generation parameter, but has been yet been implemented beyond top_p=1.0.

        n : int
            TODO! Will control the number of parallel generation calls made during gen.

        tools : Tool or list or None
            A list of `guidance.Tool` or Python functions (which will be converted to `guidance.Tool`).
            When using `tools` you must specify `max_tokens` and cannot use `regex`.

        hide_tool_call : bool
            Controls if we should hide the text generated by the model to trigger a tool call. You may want to hide the tool
            call from the model's context if you plan to change its format after the call is made.

    Not all parts of `JSON schema <https://json-schema.org/>`_ are supported. Indeed some parts
    (such as bounds on numbers) cannot really be supported in the context of LLM generation.

    Using a JSON schema:

        >>> schema = ''{ "type": "object", "properties": { "a" : {"type": "integer"} } }'
        >>> schema_obj = json.loads(schema)
        >>> lm += json(name="generated_object", schema=schema_obj)
        >>> print(json.loads(lm["generated_object"]))

    Using a ``pydantic.BaseModel``:

        >>> class Schema(BaseModel):
        ...     b: bool
        >>> lm += json(name="generated_object", schema=Schema)
        >>> print(json.loads(lm["generated_object"]))

    "\n",
    "This (written jointly with <a href=\"https://medium.com/@marcotcr\">Marco Tulio Ribeiro</a>) is part 2 of a series on <b>the art of prompt design</b> (part 1 <a href=\"https://medium.com/towards-data-science/the-art-of-prompt-design-use-clear-syntax-4fc846c1ebd5\">here</a>), where we talk about controlling large language models (LLMs) with <a href=\"https://github.com/microsoft/guidance\">`guidance`</a>.\n",
    "\n",
    "In this post, we'll discuss how the greedy tokenization methods used by language models can introduce unintended token splits into your prompts, leading to puzzling generations.\n",
    "\n",
    "Language models are not trained on raw text, but rather on tokens, which are chunks of text that often occur together, similar to words. This impacts how language models 'see' text, including prompts (since prompts are just sets of tokens). GPT-style models utilize tokenization methods like [Byte Pair Encoding](https://en.wikipedia.org/wiki/Byte_pair_encoding) (BPE), which map all input bytes to token ids in an optimized/greedy manner. This is fine for training, but it can lead to subtle issues during inference, as shown in the example below.\n",
    "\n",
    "<!-- TODO\n",
    "Standard greedy token mapping works well during training, but it can lead to subtle issues during prompting and inference. These issues arise because the greedy token boundaries often don't line up with the end of the prompt, especially when considering the generated tokens that will come next. While the end of a prompt will always align with a token boundary in practice, as the prompt is tokenized before being extended by the model, there may be instances where the first characters of the completion are part of a longer token that would span the prompt boundary. In such cases, the longer token cannot be used even though the model would expect it based on the training data.\n",

    "The inability to use tokens that span prompt boundaries can lead to subtle yet important biases in the model's output. -->\n"

    "## What about subword regularization?\n",
    "\n",
    "If you are familiar with how language models are trained, you may be wondering how <a href=\"https://arxiv.org/abs/1804.10959\">subword regularization</a> fits into all this. Subword regularization is a technique where during training sub-optimial tokenizations are randomly introduced to increase the model's robustness to token boundary issues. This means that the model does not always see the best tokenization. Subword regularization is great at helping the model be more robust to token boundaries, but it does not remove the bias that the model has towards the standard optimized (near greedy) tokenization. This means that while depending on the amount of subword regularization during training models may exhibit more or less token boundaries bias, all models still have this bias. And as shown above it can still have a powerful and unexpected impact on the model output."

This easy-to-miss source of bias can impact your results in surprising and unintended ways.\n",

    "The ReAct prompting strategy (by <a href=\"https://arxiv.org/abs/2210.03629\">Yao et al.</a>) consists of prompting a language model to generate explicit reasoning traces that contain an \"action\" step. The action step selects actions to execute in order to gain more information. ReAct can be viewed as a specific form of chain of thought combined with tool use. To execute the ReAct pattern we just need to follow the standard tool use paradigm of executing the selected actions and injecting the result (aka. Observation) back into the prompt and repeating the process until a final answer is found. This \n",

    "\n",
    "This notebook demonstrates how to get LLMs to call external tools when needed. Tools use can be implementated many ways, because there are many possible ways to design prompts that then produce outputs that can be parsed to trigger external tool calls. You can create and parse of all this syntax yourself, but Guidance also has special support commands for this that align with both the way LLMs are actually executed and with popular APIs like OpenAI. Using this syntax will also help ensure you align your prompts with any fine-tuning the LLM may have undergone for tool use (assuming the corresponding LLM object in Guidance has support built in)."

This means you give the model the actual function definition text the model sees, and you watch for the text generated by the model when it wants to make a function call. While the OpenAI Chat API abstracts away all these details, Guidance re-exposes them so you can interact with OpenAI models in the same way you would interact with any other model.\n",
    "\n",
    "So in the examples below you will see text going into the model's system prompt, and function calls coming out of the model as though you were watching the raw model output inside the `assistant` role. But behind the scenes the `guidance.llms.OpenAI` class translates this text into the corrresponding API calls. Note that the text that Guidance puts into the system prompt follows the TypeScript format that ChatGPT claims to expect on the backend, so you are seeing what things look like to the LLM itself (we just asked ChatGPT what it expects in order to get this format)."

    "\n",
    "**Function definition**: There are many ways you can tell the LLM about functions it can use, but in Guidance by convention we use the `tool_def` partial to write this definition. Each LLM object defines `tool_def` so that you can use it and know that if your model was fine tuned for tool use you will align with how the model was trained. The `tool_def` program is (normally) defined by the LLM running your program and it will convert a list of function definitions into a format that the model understands (where the function definitions are the same as the OpenAI API expects). For OpenAI models the text generated by `tool_def` is TypeScript type definitions and belongs at the end of the `system` message. *Note: Any variables not found in the current program scope fall back to the LLM object, so writing `tool_def` falls back to `llm.tool_def` unless you have explicitly defined a custom `tool_def` variable in the current program.*\n",
    "\n",
    "**Call detection:** Calls to functions by the LLM can be detected manually by setting the `stop` or `stop_regex` parameters of the `gen` command to something that signifies that the LLM is making a function call. But a cleaner way is to use the `function_call=\"auto\"` parameter. This will get passed directly to the LLM object so that it can set the appropriate `stop_regex` parameter or API parameter (to change how this work you can override the `function_call_stop` or `function_call_stop_regex` variables). There is also a `extract_function_call` variable that allows you to extract a callable object from the text returned by `gen` calls. Rather that calling this manually you can also treat the returned text just like a function and Guidance will use the `extract_function_call` command in the background, so calling the string will result in calling the tool call embedded in that string. This makes it easy to work with tool call outputs in the same way you work with other outputs from the LLM.\n",

    "- `extract_function_call`: A function that takes the text returned by the LLM and extracts a callable object from it.\n",
    "- `function_call_stop`: A string that is used to detect when the LLM is making a function call.\n",

    "Whenever you are building a prompt to control a model it is important to consider not only the content of the prompt, but also the `syntax`. Clear syntax makes it easier to parse the output, helps the LLM produce output that matches your intent, and lets you write complex multi-step programs. While even a trivial example (listing common OS commands) benefits from clear syntax, most tasks are much more complex, and benefit even more. We hope this post gives you some ideas on how to use clear syntax to improve your prompts.\n",
    "\n",
    "Also, make sure to check out <a href=\"https://github.com/guidance-ai/guidance\">`guidance`</a>. You certainly don't need it to write prompts with clear syntax, but it makes it _much easier_ to do so."

    "## Introduction\n",
    "**Note: This notebook is the code and examples from a related [the blog post](https://medium.com/@marcotcr/exploring-chatgpt-vs-open-source-models-on-slightly-harder-tasks-aa0395c31610) written jointly by Marco Tulio Ribeiro and Scott Lundberg.**  \n",

    "Open-source LLMs like [Vicuna](https://lmsys.org/blog/2023-03-30-vicuna/) and [MPT](https://www.mosaicml.com/blog/mpt-7b#building-with-mosaicml-platform) are popping up all over the place.  \n",
    "There's been [discussion](https://www.semianalysis.com/p/google-we-have-no-moat-and-neither) about how these models compare to commercial LLMs like ChatGPT or Bard, but most of the comparison has been around answers to simple questions.  \n",
    "\n",
    "As an example, the folks at [LMSYSOrg](https://lmsys.org/) did [an interesting analysis](https://lmsys.org/blog/2023-03-30-vicuna/) (+1 for being automated and reproducible) comparing Vicuna-13B to ChatGPT on various short questions, which is great as a comparison of the models as simple chatbots. However, many interesting ways of using these LLMs typically require complex instructions and/or multi-turn conversations, and some prompt engineering.\n",
    "In the 'real world', most people will want to compare different LLM offerings on _their_ problem, with a variety of different prompts.  \n",
    "\n",
    "This notebook is an example of what such an exploration might look like, comparing two open source models (Vicuna-13B, MPT-7b-Chat) with ChatGPT on tasks of varying complexity.\n",
    "\n",
    "The notebook is included here because it is also an example of how Guidance can be used to compare various models easily. We have shortened the discussion and commentary that are in the blog post, but the code and examples are here."

    "This will be similar to the Math category in [here](https://lmsys.org/blog/2023-03-30-vicuna/), with the difference that we will evaluate models as correct / incorrect on ground truth, rather than using GPT-4 to rate the output."

And they just say there’s not enough people to police this stuff. Particularly around hate speech in the company. Is that something that you-\n",
    "Elon Musk: What hate speech are you talking about? I mean, you use Twitter?\n",
    "Interviewer: Right.\n",
    "Elon Musk: Do you see a rise in hate speech? Just your personal anecdote, do you? I don’t.\n",
    "Interviewer: Personally, my For You, I would see I get more of that kind of content. Yeah. Personally. But I’m not going to talk for the rest of Twitter.\n",
    "Elon Musk: You see more hate speech personally?\n",
    "Interviewer: I would say see more hateful content in that.\n",
    "Elon Musk: Content you don’t like, or hateful. Describe a hateful thing?\n",
    "Interviewer: Yeah, I mean just content that will solicit a reaction. Something that may include something that is slightly racist or slightly sexist. Those kinds of things.\n",
    "Elon Musk: So you think if it’s something is slightly sexist it should be banned?\n",
    "Interviewer: No, I’m not saying anything. I’m saying-\n",
    "Elon Musk: I’m just curious. I’m trying to understand what you mean by “hateful content.” And I’m asking for specific examples. And you just said that if something is slightly sexist, that’s hateful content. Does that mean that it should be banned?\n",
    "Interviewer: Well, you’ve asked me whether my feed, whether it’s got less or more. I’d say it’s got slightly more.\n",
    "Elon Musk: That’s why I’m asking for examples. Can you name one example?\n",
    "Interviewer: I honestly don’t…\n",
    "Elon Musk: You can’t name a single example?\n",
    "Interviewer: I’ll tell you why. Because I don’t actually use that For You feed anymore. Because I just don’t particularly like it. Actually a lot of people are quite similar. I only look at my following.\n",
    "Elon Musk: You said you’ve seen more hateful content, but you can’t name a single example. Not even one.\n",
    "Interviewer: I’m not sure I’ve used that feed for the last three or four weeks. And I honestly couldn’t-\n",
    "Elon Musk: Then how could you see the hateful content?\n",
    "Interviewer: Because I’ve been using it. I’ve been using Twitter since you’ve taken it over for the last six months.\n",
    "Elon Musk: Then you must have at some point seen the For You hateful content. I’m asking for one example.\n",
    "Interviewer: Right.\n",
    "Elon Musk: And you can’t give a single one.\n",
    "Interviewer: And I’m saying-\n",
    "Elon Musk: Then I say, sir, that you don’t know what you’re talking about.\n",
    "Interviewer: Really?\n",
    "Elon Musk: Yes. Because you can’t give a single example of hateful content. Not even one tweet. And yet you claimed that the hateful content was high. That’s false.\n",
    "Interviewer: No. What I claimed-\n",

    "Large language models are great at generating useful outputs, but they are not great at guaranteeing that those outputs follow a specific format. This can cause problems when we want to use the outputs of a language model as input to another system. For example, if we want to use a language model to generate a JSON object, we need to make sure that the output is valid JSON. This can be a real pain with standard APIs, but with `guidance` we can both accelerate inference speed and ensure that generated JSON is always valid.\n",

    "While you can specify any constraint you want with raw guidance functions/grammars, it is often useful to enforce very simple patterns on our `gen()` calls. To do this you can specify regular expression formats to which generated text must adhere. Internally these expressions are converted to native guidance grammars (set of guidance functions).\n",

    "# Token healing\n",
    "\n",
    "Guidance uses what we call \"token healing\" to fix tokenization artifacts that normally arise at the boundary between the end of a prompt and the beginning of a set of generated tokens. Note that token healing requires direct endpoint integration to run effciently, so it currently supported only for the `guidance.models.LlamaCpp` and `guidance.models.Transformers` LLM backends.\n",
    "\n",
    "## Why token healing is needed\n",
    "Language models process tokens, which are chunks of text that often are similar to a word. This impacts how language models see text, and also how we can prompt them, since every prompt has to be a set of tokens. Encodings like [BPE](https://en.wikipedia.org/wiki/Byte_pair_encoding) that are used by GPT-style models map all input bytes to token ids in an optimized manner. This works well during training, but can lead to some subtle issues during prompting and inference because the token boundaries often don't line up with the end of the prompt if we consider the generated tokens that will also come next. Of course the end of a prompt will always align with a token boundary because the prompt is tokenized before being extended by the model, but if the first characters of the completion are part of a longer token that would span the prompt boundary, that longer token cannot be used (even though that is what the model would expect based on training data). \n",
    "\n",
    "To see why token healing is important consider the prompt \"This is a \", which is then completed with \"fine day.\" by the model, so resulting in the final string \"This is a fine day.\". If we tokenize the prompt \"This is a \" with GPT2 BPE we get `[1212, 318, 257, 220]`, and the tokenization of the extention \"fine day.\" is `[38125, 1110, 13]`. This results in a final prompt + generation token sequence of `[1212, 318, 257, 220, 38125, 1110, 13]`. If however we were to tokenize the whole string \"This is a fine day.\" jointly we instead get `[1212, 318, 257, 3734, 1110, 13]`. Which tokenization is correct? Well, the correct tokenization is the one that best communicates intent to the model. Since the model learned intent based on a optimized tokenization of the training text, that means the joint tokenization that also uses optimized matching will better align with how the model processed the training data, and so it is also likely to better communicate intent to the model. This is the reason why ending your prompt with a space is almost always a bad idea in GPT models since most word-based tokens have the space before the word, not after it.\n",

    "Note that another way to see that the \"standard\" prompt-boundary-based encoding is worse than the joint one we get with token healing is to observe that 38125 (the token id for \"fine\") is a large number, this means it is uncommon to see that token in the training data (since BPE encodings are built up greedily based on frequency). In contrast 3734 (the token id for \" fine\") is a much more common token and so more likely to clearly communicate intent to the model (since the model has seen it many times and hence had more opportunity to learn its meaning in many contexts).\n",
    "\n",
    "## How token healing works\n",
    "Guidance avoids the above tokenization artifacts automatically using a method we call \"token healing\" that backs up the generation process by one or more tokens before the end of the prompt, then constrains the first tokens generated to have a prefix that matches the last token in the prompt. This allows the generated text string to have the token encoding that the model would expect based on its training data, not an unusual alternative encoding forcing by the prompt boundary. Token healing allows you to express your prompts however you wish, without worrying about boundaries (which effect many tokens, not just space characters)."

    "While it may seem strange to us why GPT2 does not put a \"//\" after the colon character (instead writing a space), it makes sense if we think about the tokens involved. If a \"//\" was likely to come after the space, then it would have been included using the token \"://\". By sending the token id 25 (a colon) by itself to the model we are communicating that what comes next is not something that is in a token that starts with a colon (since otherwise the greedy/optimized tokenization would have used it). So GPT2 picks something that cannot be consumed into a larger token, a space character (since \": \" is not a GPT2 token)."
