Most AI today (like ChatGPT) learns by guessing the next word/token. That’s why it’s great at talking, but not at truly understanding the world.

World Models are different. Instead of predicting words, they try to learn how reality works, things like objects, movement, and cause–effect. This is closer to how humans learn by watching and experiencing.

In short:

LLMs = smart autocomplete

World Models = learning how the world behaves

This shift could shape the future of AI, robotics, and real intelligence.
