The Institute of Foundation Models at MBZUAI released PAN 2, a world model whose 29-billion-parameter diffusion backbone simulates the outcome of actions described in text as a video of up to 20 seconds at 704x1248 and 24 frames a second. The weights and code are on Hugging Face under the Apache License 2.0; the model card strongly recommends a separate guardrail, which in internal tests cut the share of harmful text-to-video requests yielding an unsafe video from 33.9% to 1.5%. The card says about two in three simulated multi-step plans contain at least one step that is not carried out.

Why it matters

Robotics and agent developers can run an open world model locally under Apache 2.0 to simulate actions before taking them, with the card warning its videos are not evidence of real events.
