In this blog, we will guide you through utilizing the LLaVA models with the llama.cpp framework for efficient image-text processing. The recent updates have made these integrations smoother, but it is essential to understand how to ensure proper functioning.

Getting Started with LLaVA and llama.cpp

To begin using LLaVA with llama.cpp, follow these steps:

• Ensure you have the latest version of llama.cpp installed in your environment.
• Download the LLaVA models from the GitHub repository.
• Integrate the image-text processing capabilities into your existing codebase, ensuring that you adhere to the new updates and best practices.

Understanding the New Updates

The recent PR merge allows llama.cpp to natively support various LLaVA models. This significantly enhances how questions are processed by using images as prompts. However, it’s crucial to verify that the processing fulfills certain token thresholds.

• When you submit a simple question using an image, the prompt must utilize at least 1200 tokens. If your prompt only totals around 576 tokens, that indicates you may still be using llava-1.5 code or the projector, which is not compatible with llava-1.6.
• Always verify that your implementation aligns with the non-default settings mentioned in the llama.cpp LLaVA readme. This ensures seamless integration across different models.

Choosing the Right Model for Optimal Performance

It is critical to choose the appropriate model for your needs, especially considering the different fine-tunes available:

• The mmproj files associated with LLaVA-1.6 can potentially have updated ViTs (Vision Transformers), which may significantly impact performance.
• Using incompatible ViTs could lead to suboptimal results, so ensure to match these with the specified mmproj of your chosen model. Mixing quantizations is permissible, but the models need to align properly.

Analogous Explanation of Token Usage

Think of tokens as ingredients in a recipe. Just like you cannot make a dish with just one or two basic ingredients, the same goes for processing a complex image-text query. You need a rich set of ingredients (tokens) to create a delightful and effective dish (the output from your model). If your recipe (prompt) consists of too few ingredients (tokens) or the wrong type of ingredients (model versions), the end dish may not turn out as expected.

Troubleshooting Common Issues

If you run into issues while setting up or running your models, consider the following troubleshooting ideas:

• Double-check your token usage by monitoring prompts against the required thresholds.
• Ensure that you are using the correct models and settings as per the LLaVA repository documentation.
• If performance issues arise, review the compatibility of the ViT models you are integrating.
