腾讯发布Hy4，支持视觉与电脑操作
腾讯混元于11月4日发布Hy4正式版，相比Hy4 preview扩大预训练和后训练规模，并首次加入视觉感知与电脑操作能力。腾讯称，Hy4提升了指令遵循、长上下文理解、长程任务和深度研究表现，现已接入WorkBuddy、CodeBuddy、TokenHub和OpenRouter等产品。第三方实测显示其在编程、视觉设计和智能体工作流方面表现 promising，但部分任务仍较困难，实际效果因任务而异。
Hy4将多模态感知、电脑操作和长程智能体工作流结合起来，并通过腾讯自有产品及第三方平台开放，为用户提供了较为丰富的实际测试入口。

Introducing Hy4
Today, we’re releasing Hy4, another major leap forward that places Hy among the strongest open-source models for the first time.
Compared with Hy4 preview, Hy4 substantially scales up both pre-training and post-training. It adds vision capabilities for the first time and delivers major gains in instruction following, long-context understanding, long-horizon tasks, deep research, and more.
Unlocking real-world productivity
With broad improvements in core capabilities and ongoing co-design with product teams across Tencent, Hy4 moves beyond benchmarks to open up more real-world use cases.
