Latent SDS Causes Pixel Artifacts via VAE-Induced Drift
August 12, 2026
Latent Score Distillation Sampling (SDS) produces structured color artifacts and high-frequency noise due to VAE-induced pixel drift. The issue arises because the optimized image can move in pixel-space directions that the VAE encoder cannot effectively constrain.
