OpenRouter is a unified AI model aggregation platform and API gateway. Instead of developers having to sign up, configure billing, and maintain separate integrations for every single AI lab (Anthropic, OpenAI, Google, Meta, Mistral, Cohere, etc.), OpenRouter serves as a single "hub."

Through one OpenAI-compatible endpoint, developers can query 400+ different frontier and open-source models.
