Moonshot AI unveils Kimi K3.1 Pro, its most capable 3T-class open-weight model: 1M-token context, MoE with 2.8T total/104B active params, multimodal. Highlights include full-project coding (games in Unreal, Unity & Godot), parametric 3D modeling in Blender/CAD, and finance work with hallucinations down 65%, matching the strongest proprietary models on coding, agentic and knowledge benchmarks. A 2-3x faster Highspeed variant ships alongside; both are live on Kimi.ai, Kimi Work, Kimi Code and the API, with full weights promised by Nov 4.
