# NagaAI documentation

> Guides and reference for the NagaAI API, which serves models from many providers in the OpenAI and Anthropic request formats.

NagaAI serves models from many providers behind one API. You send a request in the OpenAI Chat Completions, OpenAI Responses or Anthropic Messages format. NagaAI picks a provider that serves the model, converts the request for it and returns the answer in the format you sent.
