Chat & Assistants
Kimi is developed by Beijing-based Moonshot AI and is known for its extremely large context window — capable of processing hundreds of thousands of tokens — making it useful for long documents, codebases, and deep research tasks. It supports Chinese and English fluently and competes with frontier models on reasoning and comprehension benchmarks. Kimi is available via a web chat interface and API. It is particularly popular among users who need to process large volumes of text in a single session.
