PlayGen2 Real-Time World Model Uses Explicit 3D State
The architectural split between 3D state prediction and rendering avoids the drift that plagues video-frame-recurrent world models, and the laptop-scale latency shows the approach runs on consumer hardware rather than data-centre GPUs. Developers building playable-world or interactive-simulation demos can download the code and weights and extend the framework to other games or rule-based gameplay. It compares with video-only world models like Genie-style systems by trading appearance realism for spatial persistence and control.
