World model
A world model is an AI system's internal representation of how its environment works, which it can use to predict what will happen next, including what will follow from its own actions. With one, a system can plan by imagining outcomes before acting. Some world models are trained on video to generate or simulate whole scenes that a user or robot can move through.
Why it comes up
LeCun and Fei-Fei Li argue that world models, not language models alone, are the route to human-level intelligence; Hassabis's Google DeepMind builds them too (Genie), and Hinton argues large language models already have a working model of the world.
