Tencent Hunyuan Hy4 calls surge, WorkBuddy has expanded capacity tenfold

Tencent Hunyuan’s Hy4 model debuted on WorkBuddy on November 4, prompting the team to expand its inference cluster tenfold and raise free usage quotas after a surge in calls. High-end compute constraints and peak concurrency mean some periods may still hit limits, and users are advised to switch to Hy3 or use the service later in the evening. Hy3’s free-access period on WorkBuddy has been extended to November 15, 2026, at 23:59. The moves highlight how inference capacity, rather than model launches alone, is becoming the binding constraint for AI product rollouts. Watch whether Tencent adds further compute and how usage limits affect adoption.
