OpenRouter is a battle-tested AI model exchange with 400+ models from 60+ providers, processing 25+ trillion tokens weekly. Instead of hand-rolling routing logic and juggling provider keys, route through OpenRouter once and let Auto Router pick the best execution path, with automatic failover when providers degrade.

With a single API key, you can access models from free open-source options to the latest frontier models, prototype quickly, swap models in one line of code, and choose the right tool without managing multiple provider accounts.

Whether you are building an AI agent, a RAG pipeline, or a coding assistant, OpenRouter helps you focus on creating value instead of managing infrastructure. Explore the model catalogue.
