What a robot needs from a world model

Perceive

Represent geometry and scene state.

Predict

Estimate how actions change the world.

→

Plan

Choose actions that remain valid outside the screen.

Why builders care

Creative users value cinematic motion, keyframe control and fast previsualization workflows.

What still limits it

Robotics needs dependable contact, depth and causality, not merely plausible-looking video.
