Tencent releases Hunyuan Hy4, and says weights will follow
Tencent’s November 4, 2026 post says Hy4 is live in its products, adds vision and computer use, and keeps preview pricing. Open weights are described as coming later, not as a download link.
On November 4, 2026, Tencent posted that Hunyuan had released Hy4. The post says that, compared with Hy4 preview, Hy4 scales up pre-training and post-training data and compute, adds vision understanding for the first time, and adds computer use for the first time, across a command line and a graphical interface. It also says the team trained specifically for software such as Blender and CAD, and for tasks that cross applications.
The same post says Hy4’s weights will be open-sourced soon, along with a model system card, with attention to cyber and biological safety. The November 4 post describes that as a plan. It does not give a download URL. This article does not treat “soon” as a published weight release.
Tencent says Hy4 is already live on Tencent Cloud TokenHub, WorkBuddy / CodeBuddy, Yuanbao, the WeCom assistant 大圆, and ima. It says the API is also connected to OpenRouter, Hermes, and OpenCode. QQ, Honor of Kings, Game for Peace, WeChat Reading, and Tencent News are described as still being connected.
Pricing is unchanged from the preview, the post says: 6 yuan per million input tokens, 18 yuan per million output tokens, and 0.3 yuan per million tokens on a cache hit. From the post date through December 31, 2026, Hy4 on Tencent Cloud TokenHub is billed at half the list price. WorkBuddy / CodeBuddy offer a free quota from November 4 through November 15. Hy4 Flash is described as coming later. No date is given.
This directory does not have a published Hy4 or Yuanbao tool page, so there is no related-tool card on this item.
