腾讯混元发布 Hy4 正式版。相比 8 月的 Preview，进一步扩大了预训练和后训练规模，提升编程、长程 Agent、金融分析等能力，并首次加入视觉理解和电脑操作。腾讯公布的多项评测显示，其综合表现已进入开源模型第一梯队。 Hy4 现在可以结合屏幕画面、鼠标键盘和命令行操作电脑，完成跨软件任务。腾讯为此搭建了部署数百款软件的沙箱，让模型反复练习并验证结果。游戏开发方面，GameDev 和 GameLogic 评测较 Preview 分别提升 19.1% 和 9.8%。 科研任务也有新进展。腾讯称，Hy4 在无人干预下，用 1.5 小时完成了近 700 万个细胞的小鼠胚胎三维重建；还能自主定位模型训练系统的性能瓶颈，将内部测试中的训练吞吐提升 20.1%。 正式版维持 Preview 的 API 定价，腾讯云标准 API 调用在 12 月 31 日前限时五折，Token Plan 订阅在 11 月 18 日前享积分消耗 2.5 折。模型已上线腾讯云、OpenRouter 等平台，权重计划近期开源。
