PAN 2 世界模型亮相，可按描述的动作生成后续视频

Agents learn from trial and error. The expensive part is the error. A world model moves the error into simulation, which is the whole case for something like PAN 2. This is a free, open "action-conditioned world model". Takes an action you describe, and generates up to 20 seconds of video showing what would physically happen next. Its new trick is splitting the job in 2: a language model first works out the plot, then a 29B video model renders it.

Introducing PAN 2: an open foundation world model for physical intelligence. A language model predicts the next word. PAN 2 predicts the next world: what happens after each action, grounded in time, physics and space. Towards AI that simulates “what if?” before it acts. More details: https://t.co/lUX7igPOiF
