OpenRouter Founding Team
Alex Atallah and Louis Vichy started OpenRouter as a marketplace for language models. The early goal was to let developers try models from different providers through one interface and choose among them for each task.

A Single Endpoint for Multiple Model Providers
OpenRouter built its early offering around using many providers through one API. Routing then made the shared endpoint useful beyond initial experimentation, giving applications a place to select a model or provider without maintaining each integration separately.
OpenRouter Competitive Landscape
Routing Models or Hosting Them
Baseten serves models through dedicated infrastructure. OpenRouter routes requests across a catalog of models and providers. A team comparing the two should decide how much control it needs over deployment and how often it expects to change providers.
