TencentHunyuan · x · 2026-11-06

Tencent's Hunyuan Hy4 triggered usage limits across huge user numbers on its first day in WorkBuddy (Nov 4), prompting an emergency 10x expansion of the inference cluster plus raised free quotas. Hy3 stays free in WorkBuddy until Nov 15 as a fallback.

Third-party numbers: Hy4 scored 35 on Artificial Analysis Intelligence Index v5 — #2 among open models, tied with Grok 4.7, just behind Kimi K3.1 Pro (46) and 1 point from Claude Haiku 5.5, at $0.78 per task. It leads Chinese open models on agentic coding (31% on FrontierCode 2.0) while undercutting Qwen3.8 Max pricing by 13x.
