OpenRouter

OpenRouter aggregates models from multiple providers behind a single API key. Useful as a fallback provider or when you want access to models not directly supported by ModelReins.

Setup

Section titled “Setup”
Terminal window
export MODELREINS_PROVIDER=openrouter
export OPENROUTER_API_KEY=sk-or-...

Configuration

Section titled “Configuration”
{
  "provider": "openrouter",
  "openrouter": {
    "apiKey": "${OPENROUTER_API_KEY}",
    "model": "anthropic/claude-3-haiku",
    "maxTokens": 4096
  }
}

When to use OpenRouter

Section titled “When to use OpenRouter”
  • As a fallback when your primary provider hits rate limits
  • To access models not directly integrated (Cohere, Perplexity, etc.)
  • For automatic provider failover in production
  • To compare models from different providers without managing multiple API keys
