About Kimi K3

Kimi K3 is a state-of-the-art open-source AI model developed by Moonshot AI. With 2.8 trillion total parameters in a sparse mixture-of-experts architecture (896 experts, 16 activated per token) and Kimi Delta Attention hybrid attention, it represents a significant leap forward in accessible, high-performance artificial intelligence.

Our Mission

We believe that advanced AI should be accessible to everyone. By open-sourcing Kimi K3 under a Modified MIT license, we empower developers, researchers, and organizations to build, customize, and deploy cutting-edge AI on their own terms.
