Hy4 matches a top open model on agentic performance at roughly a third of the cost per task, shifting the price-performance frontier for long-horizon agent workloads. Teams building finance, frontend, research or office automation agents can try it now via Tencent's preview page and should benchmark it against Kimi K3.1 Pro before committing. If Tencent open-weights the model as signalled, it becomes a strong free-tier candidate for cost-sensitive deployments across ASEAN and beyond.
