**APIs profiled:** 13

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.
