Summary of Changes

Hello @pan-x-c, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the system's capability to work with multi-modal models. It involves a comprehensive refactoring of multi-modal data handling, from how data is formatted and tokenized to how it's passed to the underlying language models for SFT. The changes ensure that the system can effectively process and utilize combined text, image, and video inputs for training and inference, laying the groundwork for more advanced multi-modal AI applications.

Highlights

  • Multi-modal Refactoring: Existing multi-modal related functions have been refactored to improve their structure and maintainability, particularly in how multi-modal data is handled and processed.
  • SFT with Multi-modal Data: The system now supports Supervised Fine-Tuning (SFT) using multi-modal data, allowing models to be trained with inputs that combine text, images, and videos.
  • Formatter Enhancements: The SFT formatter has been updated to correctly process multi-modal inputs, including loading images and videos, and integrating them into the chat template for tokenization.
  • VLLM Model Integration: The VLLM model has been adapted to handle multi-modal inputs for both chat and generation functions, ensuring compatibility with the new multi-modal data processing pipeline.

Code Review

This pull request significantly enhances support for multi-modal models by refactoring existing functions and adding support for SFT with multi-modal data. The changes are well-structured and improve code clarity and maintainability. Key changes include refactoring formatters to lazy-load tokenizers, cleaning up the multi-modal utility functions, and making the model APIs more explicit and type-safe. I've provided a few suggestions to further improve maintainability, such as replacing a magic number with a constant, moving local imports to the top of files, and using more specific type hints.
