❯ Tencent Hunyuan apologizes for Hy4 preview queues, expands its inference cluster

apologyTencent Hunyuan said that after Hy4 preview debuted in WorkBuddy on August 28, a surge in usage driven by its improved agent capability left tasks queuing on day one, and apologized. The bottleneck hit the task queue, not conversational responses.

responseHunyuan says it has urgently expanded the Hy4 preview inference cluster and continues to reallocate resources dynamically, but stated plainly that limits on total high-end compute and peak concurrency mean queues may still appear at times, advising users to switch to Hy3 or shift off-peak. For context, WorkBuddy’s domestic version gave Hy4 preview a two-week free window and extended Hy3’s free tier to the end of September — the free access is itself part of the congestion.

real constraintQueues on launch day, plus a free promotion that has to ask users to spread out, means the binding constraint is capacity, not the model. The standard Chinese playbook of trading free usage for adoption now has to clear whether the inference cluster can take it — promotion length and concurrency caps have moved from a marketing decision to a joint one with the data center. Next to watch: whether paid conversion after the September 10 cutoff holds the traffic.
