      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the

      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,

      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

# ComfyUI_MiniCPM-V-4_5

This is an implementation of [MiniCPM-V-4_5](https://github.com/OpenBMB/MiniCPM-V) by [ComfyUI](https://github.com/comfyanonymous/ComfyUI), including support for text-based queries, video queries, single-image queries, and multi-image queries to generate captions or responses.

---

## Recent Updates

- Added `keep_model_loaded` parameter

By default, this parameter is set to False, which indicates that the model will be unloaded from GPU memory after each prediction is made.

However, if set to True, the model will remain loaded in GPU memory. This is particularly useful when multiple predictions with the same model are needed, eliminating the need to reload it between uses.

- Added `seed` parameter

This parameter enables the setting of a random seed for the purpose of ensuring reproducibility in results.

---

## Basic Workflow

- **Text-based Query**: Users can submit textual queries to request information or generate descriptions. For instance, a user might input a description like "What is the meaning of life?"

> <span style="color: green;">Chat_with_text_workflow_polished preview</span>
> ![Chat_with_text_workflow_polished preview](examples/Chat_with_text_workflow_polished.png)

- **Video Query**: When a user uploads a video, the system can analyze the content and generate a detailed caption for each frame or a summary of the entire video. For example, "Generate a caption for the given video."

> <span style="color: green;">Chat_with_video_workflow_polished preview</span>
> ![Chat_with_video_workflow_polished preview](examples/Chat_with_video_workflow_polished.png)

- **Single-Image Query**: This workflow supports generating a caption for an individual image. A user could upload a photo and ask, "What does this image show?" resulting in a caption such as "A majestic lion pride relaxing on the savannah."

> <span style="color: green;">Chat_with_single_image_workflow_legacy preview</span>
> ![Chat_with_single_image_workflow_legacy preview](examples/Chat_with_single_image_workflow_legacy.png)
> <span style="color: green;">Chat_with_single_image_workflow_polished preview</span>
> ![Chat_with_single_image_workflow_polished preview](examples/Chat_with_single_image_workflow_polished.png)

- **Multi-Image Query**: For multiple images, the system can provide a collective description or a narrative that ties the images together. For example, "Create a story from the following series of images: one of a couple at a beach, another at a wedding ceremony, and the last one at a baby's christening."

        "This image is a highly detailed, computer-generated depiction of Earth from space. The perspective showcases the planet's curvature prominently in the center of the frame against an expansive black background that accentuates its vibrant colors and intricate details.\n\nThe continents are vividly rendered with rich green hues representing landmasses, particularly noticeable on North America where Canada, parts of the United States, Mexico, and Central America stand out clearly. South America occupies the lower right portion of the globe. Above these regions lies the Arctic area, distinguished by patches of white snow covering northern Canada and surrounding areas.\n\nThe oceans appear as deep blue, providing a stark contrast to the earthy tones of the continents. Scattered across various sections of the ocean are small white specks symbolizing clouds, adding depth and realism to the atmospheric portrayal.\n\nIn the upper left corner of the image, swirling patterns resembling whirlwinds or cloud formations add dynamic visual interest. A bright sun glows softly near the top edge of the composition, casting subtle light onto part of the atmosphere above North America. This interplay of natural elements creates a captivating snapshot of our home planet set within the vastness of outer space."

Towards the upper right corner of the image, there's an intriguing element resembling either another celestial body or perhaps atmospheric phenomena such as a solar flare emitting bright light. This adds a sense of depth and mystery to the overall composition.\n\nOverall, this captivating portrayal emphasizes both the beauty and complexity of our home planet while hinting at its enigmatic surroundings in space."

When sunlight passes through the Earth's atmosphere, it collides with particles such as nitrogen and oxygen molecules. These collisions cause the light to scatter in different directions. Blue light has a shorter wavelength than other colors of light, so it is scattered more easily by these particles. This results in our eyes perceiving the color blue when we look up at the sky on a clear day."

        "The video features a striking sunset scene. The sun is prominently positioned near the horizon, casting an intense glow of orange and yellow hues across the sky. This creates a dramatic backdrop with rich gradients from bright yellows at the sun to deeper oranges and reds further away.\n\nIn the foreground, there's a silhouette of a leafless tree on the right side of the frame. Its intricate branches stand out starkly against the vibrant colors of the setting sun, adding depth and contrast to the composition. Above the tree, several birds are captured in mid-flight, their small shapes creating dynamic movement within the serene landscape.\n\nThe overall atmosphere evokes tranquility and beauty as day transitions into night. There are no visible texts or human figures in the image, allowing nature’s elements—the sun, trees, and birds—to dominate the visual narrative."
