The openrouter plugin accesses various image generation models through OpenRouter, providing:

  • Access to multiple AI models (DALL-E, Stable Diffusion, Flux, etc.)
  • Unified API for different providers
  • Image generation with colour extraction

Requirements​

  • OpenRouter API key from openrouter.ai
  • Set OPENROUTER_API_KEY environment variable

How it works​

  1. Request: Send prompt to OpenRouter API
  2. Model routing: OpenRouter routes to selected model
  3. Generation: Image generated by chosen model
  4. Response: Base64 image returned
  5. Caching: Image cached locally
  6. Extraction: K-means colour extraction
  7. Wallpaper: Image provided to output plugins

Generated image location​

Images are cached in:

~/.cache/tinct/openrouter/

Negative prompts​

Use negative prompts to exclude unwanted elements:

# Avoid certain styles
--openrouter.negative "cartoon, anime, illustration"

# Avoid artifacts
--openrouter.negative "blurry, low quality, distorted"

# Avoid elements
--openrouter.negative "text, watermark, people"
