A new benchmark, WRBench, has been introduced to evaluate the persistent state capabilities of world models in AI. Current models struggle to maintain an evolving internal world state when unobserved, instead treating camera motion as a mere tracking shot. This failure persists across various model families, scales, and control paradigms, indicating a need to prioritize the stability of physical states and worldline consistency in world model design.
