MBZUAI’s IFM Releases PAN 2, an Open 29B World Model for Physical AI

What happened

The Institute of Foundation Models at MBZUAI released PAN 2, an Apache 2.0 world model that couples an LLM (the kind of AI system trained on text to produce text) planner with a 29B diffusion transformer to simulate up to 20 seconds of action outcomes as video. The Institute of Foundation Models (IFM) at MBZUAI released PAN 2 , an open world model for physical intelligence.

IFM announced it on X on November 10, 2026. Performance: Leads 6 tested models on full plans.

The PAN 2 world model takes a scene and a text action and simulates the outcome as video. For robotics and agent developers, the pitch is simple: test a plan in simulation before acting on it.

Inputs: text plus an optional first frame. Each worker holds the full 29B model in BF16, with block offloading as fallback.

Trails MiniMax-H3 on single actions and human preference. Worst: About 2 in 3 plans miss a step.

Worst: long plans still fail often, and hardware needs are high. PAN 2 is a general-purpose world model from IFM that simulates how a scene changes after an action.
