腾讯混元跻身最强开源模型！一手实测Hy4：搭配WorkBuddy，多模态Agent交付力拉满 闻乐 2026-11-09 16:44:00 来源： 量子位 闻乐 发自 凹非寺 量子位 | 公众号 QbitAI 混元Hy4正式交卷了！ 腾讯这次上来根本不跟你客气，态度就明晃晃写在脸上： 跻身最强开源模型之列 。 770B总参数、49B激活参数， 首次引入原生视觉能力、首次支持电脑操作 。 指令遵循、长文理解和长程Agent能力也一起升级 ，电脑操作、长程Agent任务都挤进了开源阵营前排。 从preview到正式版，Hy4显著扩展了预训练和后训练的数据与训练规模，甚至还直接跑去跟一线业务搞起了“Co-Design”联合打磨。 WorkBuddy国内版、国际版已经同步完成首发接入！ 我就先在WorkBuddy里给它出了个难题：给我搓一把完全可交互的3D机械键盘出来。 75%配列、84键，键帽、轴体、定位板、PCB、电池和外壳，六层结构都安排上了。 鼠标拽着能原地炸开看内部做工，装回去还能直接上手敲，连按键下压、弹簧受力回弹的物理动效都给你算进去了。 这么一看，制作新品展示demo的活儿不就有人干了？你说是吧Hy4～ Hy4已经在腾讯云TokenHub、WorkBuddy/CodeBuddy、元宝、企业微信智能助理大圆、ima等产品上线；API同步接入OpenRouter、Hermes、OpenCode等平台。 QQ、王者荣耀、和平精英、微信读书、腾讯新闻等腾讯系产品也在持续接入中。 模型权重也将于近期开源。 那咱也话不多说，先来实测一波。 像素级视觉感知 Hy4首次引入的视觉理解，细节识别已经精细到 能够在28亿像素航拍图中，定位约2米的屋顶构件 。 这眼神儿是真不错。 那咱接下来也考考它的眼力。 第一道题， 照着一张设计截图，做一个复古风格的音乐播放器 。 先不说高清航拍图，我就想看看，它到底能不能看懂排版细节。 Hy4接单之后先把图里的配色、字体、布局挨个拆了一遍，连左侧栏宽多少像素都量好了，然后才开始写代码，把页面和播放功能一起搭起来。 中间裁切工具出了点偏差，它还换了个办法，直接分析像素来定位线条、提取颜色。 行，做题还自带尺子和色卡。 看到成品的那一刻，我盯着屏幕看了足足半分钟，不er，这还原度得99.9%吧—— 米色打底、橙红点缀、黄绿配色，再加上粗粗的大标
