Global Transport Couplings Improve Classifier-Free Guided Flows at High CFG

Alexander Tong's team introduced Global Transport (GT), label-free batch-wise optimal transport couplings for classifier-free guided flow models. GT improves generation stability under strong CFG, achieving FID 1.91 on ImageNet-256.
