Researchers have introduced EMPURPLE, a novel training-free method designed to improve the quality of distilled diffusion models. These distilled models, while faster, often suffer from degraded performance metrics like FID. EMPURPLE addresses this by recycling intermediate latents from the original diffusion model, which helps mitigate distribution mismatch issues that arise during the distillation process. This approach has demonstrated significant FID improvements, ranging from 7% to 20%, across various distillation methods including DMD2, Hyper-SD, FlashSD, and SDXL-Lightning. AI
