Fei-Fei Li at Stanford: World Models Break Down into Rendering, Simulation, and Planning
Scobleizer · x · 2026-08-10
During a talk at Stanford, Fei-Fei Li, co-founder and CEO of World Labs, provided a clear framework for understanding "World Models," breaking them down into three distinct layers:
- Rendering: Answering "what does the world look like?" This is where most current video generation models operate, primarily serving human visual consumption.
- Simulation: Addressing "how does the world actually work?" Models must understand physics, spatial relationships, and causality (e.g., how water flows), serving both humans and machines.
- Planning: Deciding "what should happen next?" based on environmental understanding.
