Jorge Diaz Chao, Konpat Preechakul, Yuxi Liu, Yutong Bai

When one ball strikes another, then another, video models should predict the consequences of each bounce. In controlled experiments on multi-ball hard-sphere dynamics, we find that the performance of standard bidirectional video diffusion degrades as the causal chain lengthens, e…Read more
