Consistency Models introduces a function that is consistent along probability-flow ODE trajectories, allowing direct mapping from noise to data. The paper presents distillation and standalone training, and demonstrates one- and few-step generation plus zero-shot inpainting, colorization and super-resolution. Latent Consistency Models apply the idea to latent diffusion models. Reported quality and step counts are specific to the datasets and settings evaluated.
A consistency function maps different noisy points on one trajectory toward the same clean endpoint.
Consistency distillation trains from a pretrained diffusion trajectory.
Standalone consistency training learns the consistency relation without a pretrained teacher.
Latent Consistency Models apply consistency-style distillation in latent space for few-step image synthesis.
Compare consistency-based samplers with diffusion baselines at matched compute and quality. Track the number of network evaluations and errors under each setting. The cited papers do not establish one-step generation as universally equivalent to long diffusion sampling.
