月之暗面发布 Kimi K3.1 Pro，称其为最强的 3T 级开源权重模型：1M token 上下文，2.8T 总参数 / 104B 激活参数（MoE），支持多模态。
官方发布给出参数规模、上下文长度和基准对比数据，开放权重时间也已明确，便于读者评估是否跟进使用。
Introducing Kimi K3.1 Pro: our most capable 3T-class open-weight model.
🔹 1M-token context, 2.8T total / 104B active params (MoE), Multimodal.
🔹 Full-project coding: games in Unreal, Unity & Godot.
🔹 Excels at parametric 3D modeling in Blender & CAD.
🔹 More reliable at finance work: Accurate modeling with hallucination down by 65%.
🔹 Matching the strongest proprietary models across coding, agentic and knowledge benchmarks.
Kimi K3.1 Pro and K3.1 Pro Highspeed (2–3× faster) are now live on http://Kimi.ai, Kimi Work, Kimi Code, and the Kimi API.
Open weights by Nov 4, 2026.
