MBZUAI Releases PAN 2, an Open 29B World Model Simulating Robots Folding Shirts

MBZUAI's Institute of Foundation Models (IFM) has released PAN 2, an open foundation world model for physical intelligence, built around "simulative reasoning" — letting an agent play out what happens before it acts.

It splits reasoning into two roles: a conceptual LLM works out what happens, when, and how the camera moves, writing it down as text; a perceptual 29B model renders how the physical world changes.
The demo shows robot hands folding a shirt — sleeves in, sides in, fold, flip — where each step builds on the previous fabric state, so every simulated step must hold for later ones to remain valid.
The model is open-sourced as a foundation for physical intelligence research.
