Kimi AI is the flagship chatbot developed by Beijing-based startup Moonshot AI. Established in 2023 by Tsinghua University alumnus Yang Zhilin, Moonshot AI has focused intensely on solving the long-context window challenge, leading China's "context length war."
Kimi AI made headlines by supporting a context window of up to 2 million Chinese characters (equivalent to roughly 1 million English words) in a free consumer product. This allows users to upload multiple thick books, financial reports, or entire code repositories, and ask Kimi to summarize, cross-reference, and analyze the contents in seconds.
Kimi AI is heavily integrated with search capabilities, providing highly accurate answers sourced from the live web. It has become the go-to tool for academic researchers, financial analysts, and legal professionals in China who need to process massive amounts of documentation daily.
