Kimi K2.5

Kimi K2.5 is the flagship AI model released and open-sourced by Moonshot AI (月之暗面) on January 27, 2026, positioned as the company's most intelligent and capable model to date . It features a native multimodal architecture supporting both vision and text inputs, toggling between thinking and non-thinking modes, and handling both conversational and agent tasks . The model offers four usage modes: fast, thinking, agent (for deep research and document generation across Word, Excel, PPT, and PDF), and agent-swarm (parallel processing for complex tasks) .

The release drove a sharp commercial inflection: within roughly 20 days, Kimi's cumulative revenue exceeded its entire 2025 full-year total, with overseas revenue surpassing domestic for the first time . BlueRun Ventures, an early and repeat investor in Moonshot AI, noted that K2.5 achieved open-source state-of-the-art results on agent, coding, image, video, and general intelligence benchmarks . The model is accessible through Kimi.com, the Kimi App, the Kimi Open Platform API, and the programming assistant product Kimi Code .
