IFM releases PAN 2, an open world model that predicts the next world, not word

IFM's PAN team announced PAN 2, an open foundation world model for physical intelligence built on a Generative Latent Prediction (GLP) architecture. Instead of predicting the next word, PAN 2 predicts the next world after each action, grounded in time, physics and space. Xing frames it as operating in an "Aristotelian" rather than "Platonic" world: six capability dimensions (obeying physics, coherence over history, persistence beyond sight, constraint conformity, viewpoint invariance, objective dynamism) plus three advanced functions — an action/plan-steerable world simulator, enabling simulative reasoning and thought experiments so agents can solve complex tasks, all fully auditable. Full paper to follow.
