The Image Model Learned in Latents, Then Finished in Pixels
A latent-to-pixel training recipe matched or beat latent diffusion baselines while cutting reported inference time by 3.18 to 4.75 times.
Summary
A latent-to-pixel training recipe matched or beat latent diffusion baselines while cutting reported inference time by 3.18 to 4.75 times.
Direct large-scale pretraining in pixel space converged much more slowly than latent-space training in the authors’ study. Their recipe first acquires generative priors in latent space, then moves to pixels during post-training while tuning initialization, data mix, prediction target, decoder and noise schedule. The resulting models matched or outperformed the tested latent counterparts and delivered reported end-to-end speedups of 3.18 to 4.75 times. Those gains belong to the evaluated architectures and training setup, not every text-to-image system.
