Fei-Fei Li has proposed a framework to clarify the definition of world models in AI, categorizing them into three core functions: rendering, simulation, and planning. She argues that while rendering focuses on visual fidelity and planning on action sequences, simulation is the crucial bridge connecting the two by ensuring geometric, physical, and dynamic consistency. Li also highlights a trend towards the convergence of these functions within a single model, suggesting that a unified world model could understand, imagine, reason, and interact with the physical world.
