Tencent Officially Releases Hunyuan Hy3: 295B MoE Model with Agent and Reasoning Capabilities
Tencent
Tencent officially launched Hy3, a 295B-parameter Mixture-of-Experts model with 21B active parameters and a 256K-token context window, under Apache 2.0. The model achieves 90% agent task-completion on Tencent's enterprise platform WorkBuddy, 78.0 on SWE-Bench Verified, and 90.4 on GPQA Diamond. Weights are available on Hugging Face (tencent/Hy3 and tencent/Hy3-FP8) and ModelScope; free API access via OpenRouter runs through July 21.
Why it matters
Hy3 matches or exceeds open-source models 2–5× its active-parameter count; at ¥1 per million input tokens it significantly undercuts Western frontier pricing. Already deployed across ~50 Tencent consumer and enterprise products at launch.
Importance: 5/5
Major open-weights release with frontier-competitive benchmarks; ≥5 independent confirmations; broadly deployed across Tencent products at launch.
