Lecture Abstract：
World models learn to predict how an environment evolves and are fast becoming a foundation for
physical AI. This talk reviews recent progress, from model-based reinforcement learning (DreamerV3) and
generative interactive world models (Genie, NVIDIA Cosmos) to self-supervised, prediction-based models
such as Meta's V-JEPA and V-JEPA 2. It then turns to world-action models, which couple a learned world
model with action for planning and control. Through examples such as V-JEPA 2-AC and Cosmos Policy, it
shows how these models enable zero-shot robot planning, before closing with the main open challenges
and opportunities.
