Summary of Changes

Hello @chenyushuo, 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 refactors the inference model architecture by introducing a new BaseInferenceModel class. This change aims to improve code organization and reduce redundancy by abstracting common functionalities such as chat template application, prompt truncation, and message-to-experience conversion into a shared base class. Concrete model implementations like TinkerModel and vLLMRolloutModel now inherit from this base class, simplifying their structure and making them more maintainable by delegating these common tasks.

Highlights

  • Introduction of BaseInferenceModel: A new BaseInferenceModel class has been introduced to centralize common logic shared across different inference model implementations, promoting code reuse and maintainability.
  • Centralized Chat Template Application: The logic for applying chat templates, previously duplicated in concrete model classes, has been moved into a new apply_chat_template method within BaseInferenceModel.
  • Consolidated Prompt Truncation: Prompt truncation logic is now encapsulated in the _handle_prompt_truncation method of BaseInferenceModel, reducing redundancy and simplifying prompt handling.
  • Unified Message-to-Experience Conversion: The convert_messages_to_experience method has been relocated to BaseInferenceModel, ensuring consistent conversion of messages into experience objects across all derived inference models.
  • Simplified Derived Models: TinkerModel and vLLMRolloutModel now inherit from BaseInferenceModel, allowing them to leverage the shared functionalities and significantly reducing their individual codebases by removing duplicated logic.

Code Review

This pull request introduces a solid refactoring by creating a BaseInferenceModel to abstract away common logic from TinkerModel and vLLMRolloutModel. This change significantly reduces code duplication and enhances maintainability. The implementation is well-executed. I have a couple of minor suggestions to further improve the readability of the new base class.
