MIT’s DRiffusion Achieves 1.4–3.7× Faster Diffusion Sampling via Draft‑and‑Refine Parallelism

MIT researchers introduce DRiffusion, a draft‑and‑refine parallel framework that uncovers intrinsic parallelism in diffusion models, delivering 1.4–3.7× speedup on three GPUs while preserving near‑lossless image quality across Stable Diffusion 2.1, SDXL and SD3 evaluated on MS‑COCO.
