Moonshot AI (moonshot.ai) is a Chinese foundation model company whose stated mission is "to seek the optimal conversion from energy to intelligence", best known for Kimi, a family of large language models with long-context capabilities (Kimi K3.1 Pro advertises a 1M-token context window) and the consumer Kimi assistant at kimi.com. The Kimi API Platform (platform.kimi.ai, formerly platform.moonshot.ai; platform.kimi.com in China) exposes OpenAI-compatible chat completion, Anthropic Messages-compatible, files, batch, models, balance, and token-estimation APIs, and the company publishes open-weight Kimi models on GitHub.
