Tencent launches Hy3, a 295B MoE model competing with GLM-5.2

Tencent has released Hy3, an open weights model with 295 billion parameters distributed across 192 experts and 21 billion active parameters. The model supports a 256K context window, integrates natively with vLLM, and achieves up to 2.95x speed improvements on NVIDIA and AMD hardware.

WHY IT MATTERS

Hy3 is a competitive alternative to proprietary models in the open model universe and highlights that open-source solutions are becoming increasingly powerful. Optimization for standard infrastructure and speculative decoding make it practical for production deployment.
