Tencent Hunyuan Releases Hy4 Flagship with Vision and Computer-Use Capabilities

On November 4, Tencent Hunyuan officially released its flagship model Hunyuan Hy4. Compared with the preview version, the official release significantly scales up both pretraining and post-training, adds vision capabilities and computer-use support for the first time, and is claimed by the company to rank among the strongest open-source models overall.

Confirmed

• Hy4 adds fine-grained image processing, chart analysis, and command-line vision and computer-operation capabilities; it can drive terminals and control a computer via the screen, making it the first vision-capable model in the Hy series
• The model is now available on Tencent Cloud, OpenRouter, CodeBuddy, WorkBuddy, and Hy AI Studio
• The company announced it will open-source the Hy4 weights
• It scores 78.9 on the OSWorld 2.1 benchmark, narrowing the gap with Claude Opus 5.5 (81.8) to single digits, ahead of GLM 5.3, DeepSeek-V4.1-Flash, Kimi K3.1 Pro, and GPT 6.1
• Official use cases listed include finance, frontend development, gaming, office work, and research, with emphasis on responsible building in cybersecurity and biosafety
• Blogger XianbaoQIAN, resharing the release news, praised the HY series for its honest evaluation practices and noted that paper author Shunyu Yao contributed to the work; the shared chart covers a 12-benchmark comparison, with Hy4 standing out on ProgramBenCh, FrontierCode 2, and others

Why it matters

Hy4 is closing in on frontier closed-source models on benchmarks like OSWorld that reflect real-world computer use; combined with the plan to open-source the weights, it further narrows the open/closed gap on agent and computer-use tasks, giving the open-source community a strong new contender.
