OpenRouter is the AI model exchange, enabling developers and enterprises to access, route, and optimize across hundreds of AI models through a single API.

Founded in 2023, the company sits between agents, applications and the model ecosystem, standardizing access to leading providers through one unified interface.

Organizations can enforce controls like per-request data handling policies, team-level access and routing permissions, spend visibility, and audit-friendly usage reporting. Intelligent routing improves cost and performance while automated failover increases reliability, and multi-provider interoperability reduces lock-in and vendor risk.
