About OpenRouter

OpenRouter is the largest, most battle-tested AI model exchange: 400+ models from 60+ providers, processing 25+ trillion tokens weekly. Instead of hand-rolling routing logic and juggling provider keys, you route through OpenRouter once and let Auto Router pick the best execution path for every request — with automatic failover when providers degrade. *openrouter.ai*

Why OpenRouter?

OpenRouter gives you a single API key to 400+ AI models - from free open-source options to the latest frontier models - so you can prototype fast, swap models in one line of code, and pick the best tool for each job without juggling multiple provider accounts.

Your credits go further than you'd expect: efficient models cover thousands of API calls, easily enough to build, iterate, and ship a real product over a span of a few weeks. Start with free models to learn and experiment at zero cost, then use your credits on more powerful models when you need peak performance.

Whether you're building an AI agent, a RAG pipeline, a coding assistant, or something nobody's thought of yet, OpenRouter lets you focus on creating value instead of managing infrastructure.
