  Moonshot AI is a Beijing-based AI lab that develops the Kimi family of
  long-context multilingual large language models. The consumer assistant is
  available at kimi.com (and kimi.ai); the developer platform at
  platform.moonshot.cn (also platform.kimi.com / platform.kimi.ai) exposes
  an OpenAI-compatible REST API for chat completions, embeddings, file
  management, fine-tuning, and model listing. Kimi models advertise very long
  context windows (8K, 32K, 128K, with newer K2.x models pushing toward 256K)
  and the platform offers multimodal text, image, and video inputs on the
  flagship Kimi K2.x line. Open-source weights for prior Kimi releases live
  under the MoonshotAI GitHub organization.
