Record completeness
Claims
Pretrained on 1,000+ games, our IPR performs robustly on levels from primitive intuition to goal-driven reasoning, and even surpasses GPT-5 overall. We find that performance improves with more training games and interaction steps, and that the model also zero-shot transfers to unseen games.
That world-model rollouts capture true underlying physics and causality rather than visual patterns, and that the G2U benchmark's visual domain gaps and heterogeneous games sufficiently isolate core mechanisms from superficial appearance.
IPR uses world-model rollouts to reinforce a VLM policy via PhysCode on a 1000+ game benchmark, achieving robust physical reasoning that improves with experience and transfers zero-shot to unseen games while surpassing GPT-5.
