Installation

1. Clone this repository into your ComfyUI custom nodes folder:

cd ComfyUI/custom_nodes
git clone https://github.com/if-ai/ComfyUI-IF_Gemini

2. Install the required Python packages:

cd ComfyUI-IF_Gemini
pip install -r requirements.txt

Usage

The Gemini node appears in the "ImpactFrames💥🎞️/LLM" category in the ComfyUI node browser.

3. Restart ComfyUI

4. Add your Gemini API key using one of these methods:

   • Shell configuration file (recommended for macOS/Linux):

     # In ~/.zshrc, ~/.bashrc, or ~/.bash_profile:
     export GEMINI_API_KEY=your_api_key_here
     

     Then restart your terminal or run source ~/.zshrc (or relevant file)

   • System environment variable:

     export GEMINI_API_KEY=your_api_key
     

   • Directly in the node: Enter your API key in the "external_api_key" field

   • In a .env file in the custom node directory:

     GEMINI_API_KEY=your_api_key
     

5. Add the "IF LLM Gemini AI" node to your workflow

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

7. 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

8. Set additional parameters as needed:

   • Prompt: Your text instructions
   • Model version: Select appropriate Gemini model
   • Temperature: Controls randomness (0.0-1.0)
   • 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
