Tencent's Hy3 AI Model So Popular It Crashed Servers—Emergency Fix Deployed

Tencent's latest AI model, Hunyuan Hy3, launched on July 6, has proven to be a victim of its own success. The model, which debuted on the office assistant platform WorkBuddy, saw such overwhelming demand that it strained computing resources, leading to service delays and user queues.

On July 8, starting around 10 AM, the platform's computing power hit a peak. At one point, over half of model calls were stuck in a queue, putting serious pressure on the system. The joint team behind WorkBuddy and Hunyuan quickly jumped into action, coordinating available resources to expand capacity and reconfigure the setup. The emergency upgrade is now complete, and the system is handling user requests normally again.

Why the Frenzy?

Hy3 isn't just another AI model—it's built for productivity. It focuses on Agent intelligence and office tasks, like document processing, PPT generation, code writing, and workflow automation. Compared to its predecessor, the preview version, Hy3's task completion success rate jumped from 72% to 90%, while average task time dropped by 34%. That kind of performance boost is a big deal for office workers and developers looking for efficient tools.

Even before the official launch, the preview version of Hy3 had already seen massive interest. Its total token call volume was 10 times that of the previous model Hy2, and in intelligent agent applications like WorkBuddy, usage surged over 16.5 times. The official release only amplified that demand, highlighting a strong market appetite for lightweight, high-performance domestic AI office tools.

User Feedback and Future Plans

The team has opened a feedback channel for users to share their experiences and suggestions. Both WorkBuddy and the Hunyuan team expressed gratitude for users' patience and enthusiasm. They're committed to continuously optimizing computing power scheduling and model service capabilities, with plans to roll out further product updates to ensure a smoother, more stable AI office experience.
