The product is an inference routing API that reduces model inference cost by finding cheaper providers within a user-defined time window. It is for developers and data teams in business environments building applications on OpenAI, Anthropic, and Gemini models. It is delivered as a hosted API and infrastructure service where clients point their existing SDK base URL to the router and add a start_within parameter, with bring-your-own-key or managed-key options.
