ONE BIG THINGThe AI industry’s biggest names are investing billions in ‘world models,’ writes Fortune’s Sharon Goldman.

Unlike existing models, these AI systems are designed not just to recognize patterns in text or images, but also to simulate how the physical world behaves. By training on millions of hours of video, these models can build an accurate internal picture of how the world works, physics and all—a crucial capability for a wide range of technologies, whether it’s to help a self-driving car predict what happens if a child runs into the street; help a home robot learn how to fold clothes; or simulate surgical procedures before a single incision is made.
