A new research paper introduces a novel evaluation protocol for world-model cascades, focusing on how a medium-level model can predict when switching to a more computationally intensive full model would improve decision-making. The proposed method uses paired exact-reset physical outcomes to audit routing decisions. Experiments on a PushT bank environment demonstrated that this prediction-derived router, while not always saving compute, could lower decision costs compared to standalone medium or full models, and a task-only router. A PyBullet audit further supported the composite task-prediction-regime router, though its advantages were limited to low compute prices. AI
