What changed
Tencent has released its AI model Hy4, which can analyze images and operate software on its own. The model was specifically optimized for coding, finance, and office work. Tencent claims it ranks second among Chinese models in independent tests, though it falls behind top models like Claude Opus 5.5 on hard math and coding tasks. The model weights will be released at a later date, and Hy4 is currently available through Tencent Cloud, OpenRouter, and Tencent apps like the Yuanbao chatbot.
What this means in practice
Hy4's image understanding capabilities allow it to recognize fine details in photos and complex diagrams. In a demo, it identified a roughly two-meter component on a warehouse roof within a massive aerial image. The model can also operate a computer for the first time, controlling software on its own. It was trained on professional tools like Blender and CAD programs, as well as tasks requiring multiple applications in sequence.
In finance and office applications, Hy4 performed well in tests with over 200 finance professionals, ranking ahead of Chinese rivals like Deepseek V4.1 Flash, Kimi K3.1 Pro, and GLM-5.3 Flash.
It also reduced hallucination rates during web research, dropping from nearly 16 to about 5 percent in internal tests. The model can collaborate with humans in real-time on Word, Excel, and PowerPoint files.
Limitations and availability
Tencent admits Hy4 still lags behind the best commercial models on hard tasks like advanced math, longer coding projects, and complex image analysis. A faster, cheaper variant called Hy4 flash is planned. The model's performance on Hy-FrontierMath T5 is significantly lower than top models, scoring 13.0 points compared to 97.5 for GPT 6.1 Sol and 91.3 for Claude Opus 5.5.
The model weights are not yet available, and Hy4 is only accessible through Tencent Cloud, OpenRouter, and Tencent apps. Pricing remains the same as the preview, with one million input tokens costing about $0.83 and one million output tokens running about $2.50. A detailed safety report will follow alongside the model weights.
