01tencent hy4: overview
What happened
On November 4 Tencent released Hy4, its latest large language model, and said it will publish weights and a system card in the coming days with attention to cybersecurity and biosafety. Hy4 adds visual understanding for the first time, covering fine-grained image processing, complex charts and mathematical visual reasoning, and also adds computer use across command-line and graphical interfaces, with dedicated training on professional software such as Blender and CAD. According to SiliconANGLE, the Hy4 Preview released on August 28 has 770 billion parameters with 49 billion active, and both versions support a 1 million-token context. Hy4 is live on Tencent Cloud TokenHub, WorkBuddy, CodeBuddy, Yuanbao, WeCom's AI assistant and ima, and through third parties such as OpenRouter, at the same price as the Preview, about $0.90 per million input tokens.
Why it matters
Together with this week's Kimi K3.1 Pro weights, Hy4 extends Chinese open-weight models into computer use and long-horizon agents, capabilities previously offered mainly by closed models. Tencent ties the model closely to its own office products such as WorkBuddy and WeCom and reports internal WorkBuddy results (average score 83.18, pass rate 96.15%); these are vendor figures without third-party replication. The actual release date of the weights, the licence terms and the system card are still to be confirmed.
Who it affects
Enterprises and developers that self-host models, Tencent Cloud and WeCom users, and teams building computer-use and office-automation agents.
