Tencent Releases Hunyuan Hy3: 295B Open-Weight MoE Under Apache 2.0
Tencent
Tencent released the full version of Hunyuan Hy3 on July 6: a 295B-parameter Mixture-of-Experts model with 21B active parameters, a 256K-token context window, and three selectable inference modes (fast, slow, hybrid). The full Apache 2.0 release removes geographic restrictions from the April preview and adds a 3.8B Multi-Token Prediction layer; hallucination rates fell from 12.5% to 5.4% vs. the preview. API pricing starts at ¥1 (~$0.15) per million input tokens.
Why it matters
Hy3 brings Tencent fully into the open-weight camp alongside DeepSeek and Qwen, with competitive pricing and Apache 2.0 licensing that allows unrestricted commercial use.
