Description
Tencent Hy4 preview is a mixture-of-experts model from Tencent's Hunyuan team, released August 28, 2026, with 49B active parameters out of 770B total and a context window over 1M tokens under Apache 2.0. It roughly doubles Hy3's parameter count and is notable as the first Hunyuan model Tencent says participated in optimizing its own training and inference infrastructure; positioned for coding, office productivity, and scientific-research agents rather than general chat.
