NVIDIA's PDD Accelerates Diffusion Models by Predicting Multiple ODE Steps
ArashVahdat · x · 2026-07-30
NVIDIA researchers introduced Parallel Decoding Distillation (PDD) to accelerate diffusion and flow models. While traditional trajectory distillation merges consecutive ODE steps into one larger step, PDD predicts multiple ODE steps in a single network evaluation, offering an elegant and efficient solution.
