World model

Sketch: a thought bubble pictures the pool ball's path before the shot; then the ball follows that path into the pocket.

A world model is an AI model that learns how the world works so it can predict what happens next, especially after an action.

Think of it like this: It is a driving simulator inside the car’s head: before turning, it pictures where the car will end up. Robots use this to plan.
