Ported from ComfyUI-IF_Gemini to support Gemini 3.0 API. Please NOTE: Open Router Functionality has been removed.

This port is for my own personal use, I am sharing back to the community as a number of people have expressed an interest in having this functionality back in CommfyUI. I am happy to accept PRs and bug reports and will integrate or resolve as possible

Features

• Text Generation: Create content, answer questions, and generate creative text formats
• Image Analysis: Describe, analyze, and extract information from images
• Image Generation: Generate images with Gemini 3's advanced image generation capabilities
• Multi-Modal Input: Combine text and images in your prompts
• Gemini 3 Enhanced Features:
  • Thinking Level control for adjustable reasoning depth
  • Media Resolution control for optimized image/video processing
  • Advanced structured output capabilities
• Customizable Parameters: Control temperature, output tokens, and other generation settings
• Chat Mode: Maintain conversation history for interactive sessions
• Batch Processing: Generate multiple outputs with a single prompt

1. Verify your API key using the "Verify API Key" button in the node

2. Configure the node:

   • For text generation, set "operation_mode" to "analysis" or "generate_text"
   • For image generation, set "operation_mode" to "generate_images"
   • Connect reference images (optional) for style-based generation

3. Set additional parameters as needed:

   • Prompt: Your text instructions
   • Model version: Select appropriate Gemini model
   • Temperature: Controls randomness (0.0-1.0)
   • Thinking Level (Gemini 3 only): Controls how much the model "thinks" before responding
     • none: Standard response (default)
     • low: Brief reasoning (1024 token budget)
     • medium: Moderate reasoning (4096 token budget)
     • high: Extensive reasoning (16384 token budget)
   • Media Resolution (Gemini 3 only): Controls image/video processing resolution
     • 1K
     • 2K
     • 4K
   • Chat Mode: Enable conversation history for interactive sessions
   • Clear History: Clear chat history when enabled (works with Chat Mode)
   • Seed: For reproducible results

Troubleshooting

• If you encounter API key errors, use the "Verify API Key" button to check its validity
• For image safety errors, try modifying your prompt to avoid content that may trigger safety filters
• Ensure your Gemini API has appropriate quotas for your usage
