Researchers have developed a method to identify physical plausibility in video diffusion models by analyzing intermediate denoising representations. They found that these models encode signals predictive of physical accuracy, even at high noise levels. This signal can be distilled into a lightweight physics verifier, which can then be used to improve inference-time mechanisms like progressive trajectory selection and reward-gradient guidance. Experiments on various video diffusion models demonstrated that these techniques can enhance physical consistency and reduce inference time without requiring fine-tuning of the generator. AI
