  title: CometAPI Unified Audio Images API
  description: CometAPI is an OpenAI-compatible aggregator that exposes a single REST surface for 500+ AI models from multiple vendors (OpenAI, Anthropic, Google, xAI, DeepSeek, Alibaba, and more). Endpoints follow OpenAI's request/response shapes for chat, embeddings, images, video, and speech, so existing OpenAI SDK clients can switch by changing only the base URL and API key.
