Continuous-Time Distribution Matching for Few-Step Diffusion Distillation

Step distillation accelerates diffusion models, with Distribution Matching Distillation and Consistency Distillation as leading methods. Continuous-Time Distribution Matching advances this by enforcing distribution matching along full PF-ODE trajectories for fewer steps.

Researchers released a paper on Continuous-Time Distribution Matching, a new distillation method for diffusion models. It extends Distribution Matching Distillation to continuous time, enabling few-step sampling without full trajectory self-consistency. This addresses limitations in prior paradigms like DMD and…
