Kimi Large Language Model

Kimi is an advanced large language model (LLM) developed by the Chinese artificial intelligence startup Moonshot AI. Officially launched to the public in late 2023, Kimi gained significant traction for its industry-leading long-context window, which allows it to process and analyze massive amounts of text in a single prompt. The brand represents a new wave of Chinese AI innovation aimed at providing safe, helpful, and highly accurate conversational experiences.

The product is primarily a software-based service hosted on servers located in China. It is designed to excel in both Chinese and English language processing. In early 2025 and 2026, the brand expanded its capabilities with the release of multimodal versions like Kimi k2.5, which support image understanding and complex data processing.

Moonshot AI, the ultimate owner, was founded by Yang Zhilin, a prominent computer scientist. The company is headquartered in Beijing and remains one of the most valuable AI 'unicorns' in the region. The brand focuses on building a seamless interface for users to interact with artificial intelligence via web, mobile, and specialized API services for developers.
