📄 Description

Related Issues or Context

This PR improves the handling of Gemini model configurations and cleans up the model list.

Key Changes:

  • Deprecations:

    • Added deprecated: true to several experimental and legacy Gemini models in their YAML configs.

  • Refactoring ( GoogleLargeLanguageModel ):

    • Fix: Introduced a temporary blacklist to prevent errors when setting thinking_config on incompatible models (e.g., gemini-2.0-flash-preview-image-generation, nano-banana). This is a short-term fix.
    • Feature: Configured correct response modalities for models with mixed-mode outputs (image, audio).
    • Refactoring: Extracted chat parameter and tool calling logic into dedicated methods (_set_chat_parameters, _set_tool_calling) to improve code organization.
    • Goal: The overall refactor makes handling different model types more robust and centralized.

  • Configuration & Validation:

    • Improvement: Replaced the legacy credentials validation method with a direct API call using genai.Client for more reliable validation at no cost.
    • Update: Changed the default model used for validation from gemini-2.0-flash-lite to gemini-2.5-flash.

  • Bug Fixes:

    • Fix: Correctly set the mime type to text/markdown for Markdown (.md) document uploads, ensuring proper handling by the Gemini API.
