Llama 3.2 Vision in Workflows

Are you ready to make a difference this Hacktoberfest? We’re excited to invite you to contribute by integrating LLama 3.2 Vision into our Workflows ecosystem! This new block for image generation will be a fantastic addition, broadening the horizons of what our platform can achieve.

Join us in enhancing our capabilities and empowering users to harness the power of vision technology. Whether you're a seasoned developer or just starting your journey in open source, your contributions will play a vital role in shaping the future of our ecosystem. Let’s collaborate and bring this innovative functionality to life!

Task description

• The task is to integrate the new Llama 3.2 Vision into workflows
• We haven't discover the model capabilities yet - that is also the part of the task 🥳
• We prefer light integration to REST API through requests library - we've found that OpenRouter provides REST API access (see this) - but if you find a better option - feel free to discuss
• We imagine the model can be implemented in similar way as other VLMs:
  • OpenAI GPT
  • Gemini
  • Claude
  • Florence 2
• please raise any issues with the task in the discussion below

Cheatsheet

• Contributor guide
• Workflows docs
• Creating Workflow block - tutorial

@PawelPeczek-Roboflow Can I have a go at it ? And can you tell me what is expected, are we talking about complete integration end to end or breaking down this issue into sub issues which can be tackled.

[PawelPeczek-Roboflow]

Hi @AHB102, thanks for engaging into the issue.

Sure, you can pick up the task - so the point is we would like to:
a) find a suitable hosted version of Llama vision model such that we can integrate via making HTTP requests
b) once this is agreed - we need to create Workflow blocks similar to https://github.com/roboflow/inference/blob/main/inference/core/workflows/core_steps/models/foundation/openai/v2.py wrapping up the model prompting for various tasks - that would require a little bit of exploration of model capabilities

[PawelPeczek-Roboflow]

First step would definitely be agreeing on API that host llama
Options I see:

• https://www.llama-api.com/
• https://openrouter.ai/meta-llama/llama-3.2-11b-vision-instruct:free

but was not investigating all of the options, which would be good to do.

I would try to find cheap and reliable third party

[AHB102]

@PawelPeczek-Roboflow I looked into hosted Llama 3.2 Vision APIs and found a few options: Together.ai (https://api.together.xyz/models) , Google Vertex AI (https://cloud.google.com/blog/products/ai-machine-learning/llama-3-2-metas-new-generation-models-vertex-ai) , Azure (https://techcommunity.microsoft.com/blog/machinelearningblog/meta%E2%80%99s-new-llama-3-2-slms-and-image-reasoning-models-now-available-on-azure-ai-m/4255167) and AWS Bedrock(https://aws.amazon.com/blogs/machine-learning/vision-use-cases-with-llama-3-2-11b-and-90b-models-from-meta/).Except Together.ai all of the other options have massive scale , it would be reliable and cheap. Hugging face also has a offering for inferencing. I checked out OpenRouter's API limits. The Llama 3.2 11B model is currently free, and the usage rates are pretty good. I think 20 requests per minute should be plenty for most things Any thoughts ?

[PawelPeczek-Roboflow]

I do not have particular bias towards any of the vendor - I even see that the decision which is most handy for people to use is strictly related to individual preferences of the consumer.
I believe AWS / Google / MS would be the "stable" choice, whereas I expect other third parties to be more attractive cost-wise.
One thing to keep in mind is also how easy it is to integrate - I remember that at least part of google API clients are bulky and require setting API key at process-level, not for individual invocation (which is 🔴 flag for multi-tennant deployments which we do with workflows).

I see the construction of the block in the following way:

• we support parameters required to deal with model
• and on the "orthogonal" axis - we do support 2 parameters - api_key and provider - which will choose backend to use. This approach do also have cons, but at least we do not need multiple blocks to handle the same model from different providers
• we could start easy with one provider, ensuring extensibility for the future
  wdyt?

[AHB102]

That sounds great! This approach provides a solid foundation for future scalability and flexibility. By not committing to a single vendor upfront, we can adapt to evolving needs and avoid potential vendor lock-in.

To start, I suggest we explore OpenRouter. It offers free API usage for Llama 2.3 11B, making it ideal for initial testing and development. Additionally, its compatibility with familiar libraries like requests and openai can streamline the integration process and minimize security risks.

Once we have a robust core structure in place, we can easily pivot to other providers. wdyt ?

[PawelPeczek-Roboflow]

yeah, that sounds right

[AHB102]

I've been diving into the Workflow Block (https://github.com/roboflow/inference/blob/main/inference/core/workflows/core_steps/models/foundation/openai/v2.py) and feel comfortable with the workings of the OpenAIBlockV2 class. I'm about to start writing code. Any advice for getting the most out of it? When modifying the inference core, I understand that I need to include test cases, right?

[PawelPeczek-Roboflow]

yeah, tests are recommended.

Here is our block creation guide: https://inference.roboflow.com/workflows/create_workflow_block/

[PawelPeczek-Roboflow]

you can find information how to run development smoothly

to test remote apis - we usually create unit-tests agains mocks - and place some integration test skipped if API key not provided

[PawelPeczek-Roboflow]

example integration test: https://github.com/roboflow/inference/blob/main/tests/workflows/integration_tests/execution/test_workflow_with_open_ai_models.py

and unit test for the same block: https://github.com/roboflow/inference/blob/main/tests/workflows/unit_tests/core_steps/models/foundation/test_openai.py

[AHB102]

@PawelPeczek-Roboflow Let's get v1.py for Llama working, I'll be focusing on getting it functional before tackling test cases. I'll definitely ask for your input and help along the way, and I'll keep you updated on how it's going. Thanks for the docs 😁

[PawelPeczek-Roboflow]

hi there :) anything I can help you with?
