AI TRENDS | Tencent Hunyuan Says Hy4 Preview Calls Surge, WorkBuddy Expands Capacity

According to Jin10, Tencent Hunyuan said Hy4 preview calls have surged since its first launch on WorkBuddy on August 28, 2026, and WorkBuddy has urgently expanded capacity. The company said the model's significantly improved agent capabilities drew positive feedback from users and developers, caused queueing in WorkBuddy's task queue on the first day, and led it to apologize for the inconvenience. Tencent Hunyuan said it has urgently expanded the Hy4 preview inference cluster and will continue to dynamically allocate resources, but queueing may still occur at certain times because of limited high-end computing capacity and concentrated peak concurrency.
