World Model

AI system's internal representation of how the world works.

In Simple Terms

AI system's internal representation of how the world works.

What is World Model?

World models are internal representations that AI systems build of how the world operates—physics, causality, social dynamics. They enable prediction, planning, and reasoning about novel situations. Whether LLMs have true world models is debated; they show some world knowledge but fail at tasks requiring deep understanding. Building better world models is a key AI research direction.
