World Model

An AI system's internal representation of how the world works — understanding physics, cause and effect, and spatial relationships.

An AI system's internal representation of how the world works — understanding physics, cause and effect, and spatial relationships. Building better world models is seen as key to achieving AGI. Current LLMs have surprisingly good implicit world models but still make basic physical reasoning errors.
