What is Kimi (Moonshot AI)?

Advanced AI assistant by Moonshot AI featuring the K2.5 multimodal model with long-context processing, visual coding, agent swarm orchestration, and deep research capabilities.

Kimi is the flagship AI assistant developed by Moonshot AI, a Beijing-based company founded in March 2023 by Yang Zhilin, Zhou Xinyu, and Wu Yuxin — all Tsinghua University alumni. Moonshot AI has rapidly become one of China's most prominent AI companies, often grouped among the country's so-called AI Tigers for its ambitious pursuit of artificial general intelligence through large language models.

The platform's most recent milestone is the Kimi K2.5 model, released in January 2026. K2.5 is a multimodal upgrade that added native vision capabilities through a 400-million-parameter vision encoder called MoonViT. This model can process both images and video input, enabling agentic tasks such as replicating website user journeys from video demonstrations alone. The K2.5 release came just three months after the K2 model, reflecting Moonshot's aggressive development cadence.
