OpenAPI Specification

openapi: 3.1.0
info:
  title: vLLM OpenAI-Compatible Server Audio API
  version: '1'
  description: 'vLLM is a high-throughput open-source inference and serving engine for

    LLMs. Running `vllm serve` exposes an OpenAI-compatible REST API plus

    vLLM-specific endpoints. Authentication is via a server-startup

    `--api-key` flag; clients supply it as a Bearer token in the

    Authorization header (matching the OpenAI Python client).
