  title: Chat Chutes API
  description: 'Specification of the Chutes API. Chutes is a permissionless, serverless AI compute platform on Bittensor Subnet 64. It exposes two REST surfaces: an OpenAI-compatible inference endpoint at https://llm.chutes.ai/v1 for chat completions and model listing across hundreds of open-source models, and a management API at https://api.chutes.ai for building images and deploying, listing, and operating chutes (serverless AI apps). All requests authenticate with a Bearer API key (prefix `cpk_`).'
