REST API to list, retrieve, deploy, update, and delete chutes (serverless AI apps), plus templated vLLM/diffusion deploys, warmup, utilization, miner means, and TEE attestation evidence.

title: 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_`).
