MrFlow

Training-free acceleration for flow-matching text-to-image models: generate low-res, upsample in pixel space with Real-ESRGAN x2, re-encode with scheduler-consistent noise injection, then 1-step high-res refine; 10x+ speedup on Qwen-Image, works on FLUX.1-dev, Z-Image and distilled models, with ComfyUI support.
