Title: PixelGen: Improving Pixel Diffusion with Perceptual Supervision
Abstract:
arXiv:2602.02493v2 Announce Type: replace-cross Abstract: Pixel diffusion generates images directly in pixel space, avoiding the VAE artifacts and representational bottlenecks of two-stage latent diffusion. Recent JiT further simplifies pixel diffusion with x-prediction, where the model predicts clean images rather than velocity. However, the standard pixel-wise diffusion loss treats all pixels equally, spending model capacity to perceptually insignificant signals and often leading to blurry sam
