The argument goes as follows. VLMs are not explicitly trained to predict the future, and are thus unreliable at the kind of geometric, spatial, and physical reasoning abilities needed to predict fine-grained consequences of actions. In contrast, a world model allows a robot to “imagine” the future in order to plan, e.g., by (1) generating a video of imagined success and using an inverse dynamics model to infer
