MBZUAI's IFM releases PAN 2, an Apache 2.0 world model with a 29B diffusion transformer

The Institute of Foundation Models (IFM) at MBZUAI released PAN 2, an open world model under the Apache 2.0 license. According to MarkTechPost, PAN 2 couples an LLM planner with a 29B-parameter diffusion transformer and simulates up to 20 seconds of action outcomes as video.

What was released

• Model: PAN 2, described as a world model for physical AI
• Developer: Institute of Foundation Models (IFM) at MBZUAI
• License: Apache 2.0
• Architecture: an LLM planner paired with a 29B diffusion transformer
• Output: video simulating the outcomes of actions, up to 20 seconds long

Context window, API pricing, benchmark scores and training cutoff date are not yet disclosed.

How it works

PAN 2 splits the task into two components. The LLM planner handles the action side, and the 29B diffusion transformer renders the simulated outcome as video. The simulation horizon is up to 20 seconds per run.

What this means

PAN 2 pairs language-model planning with video-based simulation of action outcomes, and it ships under Apache 2.0. Teams working on physical AI can examine the two-part design and the 29B diffusion transformer directly. Performance comparisons will depend on benchmark results and technical documentation from IFM, which are not yet available here.
