PHYSIX OBSERVATION

Hy4 packs visual understanding into the agent workflow, letting the model watch video to replicate games and operate Blender - a stronger signal than topping the benchmarks. With low API prices plus a free window, Tencent is courting long-horizon task developers, but real-world stability still needs testing in real scenarios.
