## Plain English

A model that generates a place you can move around in, not just a picture of one.

## Example

A robot-learning team generates thousands of simulated kitchen variants with Genie 3 and trains a manipulation policy inside them instead of teleoperating real robots for months.

## Why it matters

World models are the training substrate of the physical-AI wave: simulated experience is becoming the training data, and 24 fps interactive generation makes it usable live.
