Tencent Hunyuan — the Hy line

Tencent’s Hunyuan Hy line is the native lineup of BD LLM Token Hub: Hy4-preview (770B MoE, Apache 2.0) is already served on Tencent Cloud TokenHub, with Hy3 and the Hy-MT2 translation family below it.

Hy4-preview hit #1 on OpenRouter’s weekly board (14.7T tokens, +379% WoW) in early September.

Who they are

Tencent builds the Hunyuan family for its own products and clouds. Hy4-preview is its largest open-weight release (Apache 2.0, FP8 variant included), used in WorkBuddy, CodeBuddy, Yuanbao and ima — and served directly through Tencent Cloud TokenHub.
