Yann LeCun, a pioneering AI researcher, provides his definition of what constitutes a world model in this X post. A world model is an AI system's internal representation of how the physical world works, enabling it to predict outcomes of actions and understand environmental dynamics without explicit programming. This concept is fundamental to developing more intelligent AI systems capable of reasoning and planning in complex environments.
