This plugin provides integration with various models available through the OpenRouter API via the ElizaOS platform.

Add the plugin to your character configuration:

"plugins": ["@elizaos/plugin-openrouter"]

The plugin requires the OpenRouter API key and can be configured via environment variables or character settings.

Character Settings Example:

"settings": {
  "OPENROUTER_API_KEY": "your_openrouter_api_key",
  "OPENROUTER_BASE_URL": "https://openrouter.ai/api/v1", // Optional: Default is OpenRouter endpoint
  "OPENROUTER_SMALL_MODEL": "google/gemini-flash", // Optional: Overrides default small model
  "OPENROUTER_LARGE_MODEL": "google/gemini-pro", // Optional: Overrides default large model
  "OPENROUTER_IMAGE_MODEL": "x-ai/grok-2-vision-1212", // Optional: Overrides default image model
  // Fallbacks if specific OPENROUTER models are not set
  "SMALL_MODEL": "google/gemini-flash",
  "LARGE_MODEL": "google/gemini-pro",
  "IMAGE_MODEL": "x-ai/grok-2-vision-1212"
}

.env File Example:

OPENROUTER_API_KEY=your_openrouter_api_key
# Optional overrides:
OPENROUTER_BASE_URL=https://openrouter.ai/api/v1
OPENROUTER_SMALL_MODEL=google/gemini-flash
OPENROUTER_LARGE_MODEL=google/gemini-pro
OPENROUTER_IMAGE_MODEL=x-ai/grok-2-vision-1212
# Fallbacks if specific OPENROUTER models are not set
SMALL_MODEL=google/gemini-flash
LARGE_MODEL=google/gemini-pro
IMAGE_MODEL=x-ai/grok-2-vision-1212

• OPENROUTER_API_KEY (required): Your OpenRouter API key.
• OPENROUTER_BASE_URL: Custom API endpoint (default: https://openrouter.ai/api/v1).
• OPENROUTER_SMALL_MODEL: Specific model to use for TEXT_SMALL and OBJECT_SMALL. Overrides SMALL_MODEL if set.
• OPENROUTER_LARGE_MODEL: Specific model to use for TEXT_LARGE and OBJECT_LARGE. Overrides LARGE_MODEL if set.
• OPENROUTER_IMAGE_MODEL: Specific model to use for IMAGE_DESCRIPTION. Overrides IMAGE_MODEL if set.
• SMALL_MODEL: Fallback model for small tasks (default: "google/gemini-flash"). Used if OPENROUTER_SMALL_MODEL is not set.
• LARGE_MODEL: Fallback model for large tasks (default: "google/gemini-pro"). Used if OPENROUTER_LARGE_MODEL is not set.
• IMAGE_MODEL: Fallback model for image analysis (default: "x-ai/grok-2-vision-1212"). Used if OPENROUTER_IMAGE_MODEL is not set.

The plugin currently provides these model types:

• TEXT_SMALL: Optimized for fast, cost-effective text generation using the configured small model.
• TEXT_LARGE: For more complex text generation tasks requiring larger models, using the configured large model.
• OBJECT_SMALL: Generates structured JSON objects based on a prompt, using the configured small model.
• OBJECT_LARGE: Generates structured JSON objects based on a prompt, using the configured large model.
• IMAGE_DESCRIPTION: Analyzes images and provides descriptive text and titles, using the configured image model.

Note: Features like Image Generation, Audio Transcription, and Embeddings are not currently implemented in this specific OpenRouter plugin.
