Kimi is an advanced artificial intelligence chatbot developed by Beijing-based company Moonshot AI. Launched in October 2023, Kimi has rapidly gained popularity, boasting over 36 million monthly active users by October 2024.

One of Kimi’s standout features is its exceptional capacity to process extensive textual inputs. Initially, it supported up to 200,000 Chinese characters in a single prompt, and by March 2024, this capability expanded to an impressive 2 million characters. This vast context window enables Kimi to efficiently analyze and summarize lengthy documents, making it an invaluable tool for researchers and professionals dealing with substantial textual data.

In January 2025, Moonshot AI introduced Kimi k1.5, an enhanced version of the original model. Kimi k1.5 is a multimodal AI system adept at understanding and processing both textual and visual inputs, including photos and videos. It has demonstrated superior performance in areas such as mathematics, coding, and multimodal reasoning, even surpassing some of OpenAI’s models in these domains.

Kimi’s development reflects China’s rapid advancements in the AI sector, with companies like Moonshot AI emerging as significant contributors to the global AI landscape.
