New method enhances few-step generation for diffusion models

Researchers have developed a new method called Reflow with Marginal Distribution Alignment to improve the efficiency of diffusion and continuous-flow generative models. These models, which solve learned ODE dynamics for high-quality generation, often require many steps for accurate discretization. The new approach addresses a limitation in existing reflow-based distillation techniques, which can under-determine the distribution induced by the student model. By introducing a marginal-alignment regularizer, the framework ensures better alignment between the student and teacher model distributions, leading to improved generation quality with fewer steps. Experiments on benchmark models demonstrate the effectiveness of this method for few-step generation. AI
