Hy4 is Tencent’s flagship model, and this full release follows the Hy4 Preview from August. It adds two big things: it can see, and it can use a computer.
Here’s what’s new:
Visual understanding for fine-grained images, complex charts and math diagrams
Computer use across command-line and graphical interfaces, with training on professional software like Blender and CAD
Better instruction following, long-context comprehension and long, multi-step agent tasks
An internal hallucination rate that fell from 12.95% to 7.2%, and errors from unsupported assumptions that fell from 23.1% to 5.6%
On Tencent’s own tests, Hy4 scored 3.04 in a blind financial evaluation (213 professionals, 579 tasks), ahead of DeepSeek-V4.1-Flash-1017 at 2.97 and Kimi K3.1 Pro and GLM-5.3 at 2.68. It also scored 83.18 on WorkBuddy with a 96.15% pass rate. These are Tencent’s own results, not independent tests.
It’s aimed at office tasks, financial analysis and game development, and Tencent says product teams helped train and evaluate it against real workflows.
Availability: it’s on Tencent Cloud TokenHub, OpenRouter, Hermes and OpenCode, and inside Tencent’s apps WorkBuddy, CodeBuddy, Yuanbao, ima and WeCom’s AI assistant. WorkBuddy and CodeBuddy are free from November 4 to 15, and TokenHub has 50% off through December 31. The model weights aren’t out yet, and Tencent says they’ll come in the coming days, along with system cards.
Good fit if you build agents or workflows that need a model that can read charts and documents and operate software, and you want to try it before the weights land.
