OpenRouter

OpenRouter Overview

OpenRouter is the unified interface for LLMs — one API to access 500+ models from every major provider with the best prices, automatic fallbacks, and smart routing. Find the best model and price for your prompts through a single OpenAI-compatible endpoint.

  • 500+ Models in One API: Access frontier and open-weight models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and more through a single unified endpoint.
  • Best Price Discovery: Compare live prices per model and per prompt to find the cheapest provider for your exact request.
  • Intelligent Routing: Route each prompt to the best model with automatic fallbacks when providers fail, time out, or degrade.
  • Prompt Caching: Automatic prompt caching cuts cost and latency by reusing cached prefixes across requests.
  • Per-Prompt Model Selection: Choose a different model for every prompt — quality-first when it matters, cost-first when it doesn't.
  • Rankings & Leaderboards: Compare models side-by-side with human-preference rankings to pick the best model for your use case.
  • Unified API & SDKs: OpenAI-compatible API with official SDKs for Python, JavaScript, and more — switch models with a single string change.
