PAN 2

PAN 2 is an open 29B-parameter diffusion transformer that simulates how a scene changes after a text action, outputting video up to 20 seconds at 704×1248 and 24 fps. It pairs an LLM planner for structured world-state reasoning with a video model trained from scratch. IFM self-reports 34.0% full-plan completion on 100 multi-step tasks, the highest of the models it tested, but MiniMax-H3 leads on single actions and human preference. Weights, training code and inference code are released under Apache 2.0.
