About Kimi

Kimi, developed by Moonshot AI, is a proprietary model with a 2 million token context window, one of the largest available from any AI provider. The model specializes in processing extremely long documents, research papers, entire books, and extensive codebases in a single request. Its massive context window enables use cases like comprehensive literature reviews, full-repository code analysis, and multi-document legal review that would require multiple passes with shorter-context models. Kimi powers Moonshot AI's consumer chatbot of the same name, which has gained significant traction in the Chinese market. The model handles Chinese and English with strong bilingual capabilities. Its extreme context length positions it for research-intensive and document-heavy enterprise applications where processing large volumes of text without chunking or summarization loss is critical.
