The unified interface for LLMs
OpenRouter is a managed LLM gateway providing a single OpenAI-compatible API to access 300+ AI models from 60+ providers. It enables developers to swap models without rewriting code with automatic failover and consolidated billing.
Access models from 60+ providers through a single OpenAI-compatible endpoint
Automatic failover with continuous health monitoring
Routes queries to optimal models based on complexity and cost
Send images, PDFs, audio through the unified API
Zero-logging by default with data policy routing
Built-in caching, budgets, and spend controls
Integrates with 15+ monitoring platforms
TypeScript and Python SDKs with OAuth and streaming
Different models for different tasks through one API
Reliable model access with failover and dynamic selection
Benchmark models without separate accounts
Auto-routing minimizes costs
Best for developers who want to compare models through hands-on testing rather than reading benchmarks. The unified API removes the friction of managing multiple provider integrations.
Best for prompt engineers who need model flexibility — test across 300+ models, avoid provider lock-in, and use intelligent routing to optimize cost vs. quality for every query.
