The model is predicting what the state of the world would look like after a given action.

Along with entertainment, they can be used for simulation training for robots. And allow for imagining potential trajectories

Marble is not that type of world model. It generates static Gaussian Splat assets that you can render using 3D libraries.

Whenever I see these and play with models like this (and the demos on this page), the movement in the world always feel like a dolly zoom. Things in the distance tend to stay in the distance, even as the camera moves in that direction, and only the local area changes features.
