Kimi 发布 K3.1 Pro 开源权重模型，2.8T 总参数、1M token 上下文
Introducing Kimi K3.1 Pro: our most capable 3T-class open-weight model.
Kimi 发布 K3.1 Pro，这是其最强的 3T 级开源权重模型，采用 MoE 架构，总参数 2.8T、激活参数 104B，支持 1M token 上下文与多模态。官方称其在编码、智能体和知识类基准上可对标最强闭源模型，并支持 Unreal、Unity、Godot 全项目游戏开发与 Blender、CAD 参数化 3D 建模，金融场景幻觉下降 65%。K3.1 Pro 与速度提升 2–3 倍的 K3.1 Pro Highspeed 已在 Kimi 官网、Kimi Work、Kimi Code 和 Kimi API 上线，开源权重计划于 2026 年 11 月 4 日发布。

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 https://t.co/85jA71X9gw, Kimi Work, Kimi Code, and the Kimi API.
