IFM launches PAN 2 world model grounded in time, physics and space for agent what-if simulation
kimmonismus · x · 2026-11-11
The Institute of Foundation Models (IFM) launched PAN 2, a world model built so AI agents can rehearse what-ifs before acting.
PAN 2's core claim is grounding in three axes:
- Time: actions stay in causal order, each step setting up the next;
- Physics: swap a strawberry for a rubber duck or change the liquid, and it correctly simulates how the splash changes;
- Space: scenes stay coherent as the camera moves and objects leave the frame.
The author's framing: physics correctness is what matters most — if the world model gets it wrong, the agent acting on it gets it wrong too. Three demos follow, one per axis.
