SD3.5-Flash: few-step distillation brings quality image generation to consumer devices
ducha_aiki · x · 2026-09-12
The ECCV 2026 paper SD3.5-Flash introduces an efficient few-step distillation framework that brings high-quality Stable Diffusion 3.5 image generation to consumer devices.
Key methods:
- Reformulated distribution-matching objective tailored for few-step generation of rectified flow models
- "Timestep sharing" reduces gradient noise; "split-timestep fine-tuning" improves prompt alignment
- Pipeline optimizations (text encoder restructuring, specialized quantization) enable fast, memory-efficient deployment
Large-scale user studies show it consistently outperforms existing few-step methods, spanning phones to desktops and making generative AI practical on-device.
