TREE NEWS update: Tencent’s Hunyuan Hy4 model debuted on WorkBuddy on November 4, and the team has urgently scaled its inference cluster tenfold and raised users’ free trial quota to handle the surge in calls. High-end compute constraints and peak concurrency mean some periods may still hit usage limits; users are advised to switch to Hy3, whose free access on WorkBuddy is extended to November 15, 2026, or to use off-peak evening hours.
Tencent Hunyuan Hy4 Sees Surge in WorkBuddy Calls, Cluster Scaled 10x
The tenfold cluster expansion within days of launch is the real signal here: demand for Hunyuan Hy4 on WorkBuddy outran Tencent's provisioning, and the fallback to Hy3 plus off-peak steering shows capacity, not features, is the binding constraint. That matters for anyone building on Chinese model APIs, where high-end compute scarcity can turn a launch-day spike into a throttled experience. The open question is whether the cluster build-out keeps pace with sustained usage, or whether quota caps and model downgrades become a recurring pattern around peak concurrency.
