Summary of Changes

Hello @wggcch, 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 ChatLitellm node by integrating image upload capabilities. This upgrade allows users to leverage vision-enabled models through LiteLLM, providing a more versatile chat experience. The changes include new UI parameters for controlling image input and resolution, along with underlying code modifications to process these multimodal inputs effectively.

Highlights

• Image Upload Capability: The ChatLitellm node now supports image uploads, bringing parity with vision models from providers like Azure and OpenAI.
• New Configuration Options: Introduced 'Allow Image Uploads' (boolean) and 'Image Resolution' (options: Low, High, Auto) parameters to the ChatLitellm node for controlling image input.
• Version Update & Description: The ChatLitellm node's version has been updated to 2.0, and its description now clarifies that image uploads require a LiteLLM model marked with supports_vision=true.
• Internal Multimodal Integration: The implementation now utilizes FlowiseChatOpenAI and its setMultiModalOption method to handle multimodal input, specifically for images.

Code Review

This pull request adds image upload support to the ChatLitellm node, bringing it to feature parity with the ChatOpenAI node. The changes are well-implemented, introducing new optional parameters for enabling image uploads and setting image resolution. The code correctly uses a custom FlowiseChatOpenAI wrapper to handle the multimodal configuration, following the existing pattern in the codebase. The changes are consistent and appear to be correct. I have no specific comments for improvement.
