OpenRouter

OpenRouter is a single interface for accessing leading LLMs and other AI models through one API. It acts as a routing layer between providers: integrate once, then switch between hundreds of models and dozens of vendors without rebuilding your stack.

One API for many models

OpenRouter supports 500+ models and 60+ active providers, spanning major commercial options and open models. It’s compatible with the OpenAI SDK, so you can connect it to existing projects with minimal code changes.

Reliability and failover

With distributed infrastructure, OpenRouter can automatically reroute requests to alternative providers when one is unavailable. This improves uptime and keeps AI applications stable under higher load.

Cost and performance control

OpenRouter helps you manage spend by choosing models based on price, speed, and output quality.

• Compare and test different models for your use case
• Pick the best balance of cost vs. performance
• No subscriptions; pay only for actual token usage

Built for developers and teams

OpenRouter fits independent developers and startups as well as larger companies that need scalability, redundancy, and broad model choice through a single API.
