Moonshot AI

Kimi Model API

Moonshot AI's Kimi model family excels at long-text understanding, multi-turn conversations, and creative writing. Examples here default to OpenAI Chat Completions; the same model ID can also be called via the Anthropic Messages or Responses API protocols, depending on model support.

POSThttps://nexusflow.hk/v1/chat/completions

This is the default example endpoint. For multi-protocol usage, see Multi-Protocol Support, Anthropic Messages, and Responses API.
