New Penn world models course offers public materials

A Penn instructor announced CIS 6280 · World Models on September 11, 2026, saying the course was already six lectures in. Slides, demos and readings were public, with more materials planned throughout the fall. The instructor frames world models as a way for AI to learn from observing and interacting with the world, beyond what humans have written down. Planned hands-on work includes building an environment, training a world model and learning a policy, plus a final research project with a leaderboard.
