Hy3 is Tencent Hunyuan's production-grade Mixture-of-Experts model — 295B total parameters with only 21B active per pass (192 experts, top-8 routing), the upgraded release built on the Hy3-preview line. It expands RL-training scale and post-training data quality for further gains in reasoning, long-context, and agentic tasks, reaching results comparable to flagship models several times its parameter size. It serves a 256K-token context window (text in, text out) with configurable reasoning effort, and is built for real-world coding, tool use, and multi-step agent workflows at a strong quality-to-cost ratio.
