Hy3
Hy3 is Tencent’s stable follow-up to Hy3 Preview, trained with higher-quality post-training data and feedback from deployed products. It retains a 295B-parameter sparse architecture with 21B active parameters and a 256K context. The model supports both fast responses and slower reasoning, with improvements to tool use, coding, and productivity workflows. Apache-licensed weights replace the preview’s custom community license. Official API access and integration into Tencent products provide hosted alternatives to private deployment.
