Why we picked it

Cost-per-task of US$0.57 with top-5 agentic performance makes Hy4 a strong price-performance option for agent workloads. Developers evaluating Chinese alternatives to US frontier models can compare it directly on Agent Arena's session-based leaderboard. The model is relevant to ASEAN teams building on Tencent's ecosystem, where Hunyuan integration is already common.

Tencent Hunyuan's Hy4 is now the #1-ranked Chinese model on Agent Arena. The ranking is based on more than 12,000 real-world long-horizon agentic sessions from the platform's global user community. Hy4 delivers a +5.4% net improvement and is the only Chinese lab model inside the top 5. It sits on the Agent Arena Pareto frontier with a median cost of US$0.57 per task.

Tencent Hunyuan releases Hy-Nomas open source interactive video world model

Consumer-GPU inference lowers the hardware barrier that keeps most world models out of hobbyist and lab budgets, and LoRA hooks make it a practical base for robotics simulation. Developers building interactive video, embodied AI or game prototyping can grab the weights from Hugging Face and fine-tune on their own data. Compared with closed world models behind APIs, Hy-Nomas gives full control over generation pipelines.

Tencent Hunyuan releases WorkForge for training work agents

The dual programmatic-plus-semantic verifier design addresses the hardest part of agent training: rewarding long-horizon tasks without human grading. Teams building enterprise work agents can reuse the recipe to generate their own verifiable task suites from internal workflows rather than hand-crafted benchmarks. It sits alongside agent-environment efforts like task synthesis pipelines from other labs but anchors everything in expert-derived, evidence-backed tasks.
