Summary of Changes

Hello @DeiuDesHommies, 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 enhances the openai_api_compatible plugin by integrating support for Zhipu AI's distinct thinking mode parameter structure. The change ensures that the plugin can seamlessly handle Zhipu's thinking parameter, which specifies whether thinking mode is enabled or disabled, while also preserving full compatibility with existing vLLM/SGLang chat template configurations. This update improves the plugin's adaptability across various large language model providers.

Highlights

• Zhipu AI Thinking Mode Support: Added support for Zhipu AI's specific top-level thinking parameter format, allowing the plugin to correctly interpret {"type": "enabled"} or {"type": "disabled"}.
• Backward Compatibility: Maintained compatibility with existing vLLM/SGLang chat_template_kwargs for enable_thinking and thinking parameters.
• Version Bump: The plugin version has been updated from 0.0.28 to 0.0.29.

Code Review

This pull request correctly adds support for Zhipu AI's 'thinking' mode by including a top-level thinking parameter in the API request, while maintaining backward compatibility with the existing chat_template_kwargs format. The version bump is also appropriate. The changes are logical and well-contained. I have provided one suggestion to improve code readability and minor efficiency by refactoring how the chat_template_kwargs are handled. Overall, this is a good enhancement.
