First 6-step LoRA adapters with no upsampling step, ~5x faster [N]

Summary

PrunaAI released 6-step LoRA adapters for Qwen-Image-2.1 that cut image generation from 40 steps to 6, with one variant removing the prompt-upsampling step entirely for ~5x faster end-to-end generation.

Hey! We published a set of 6-step LoRAs, one without the upsampling step: https://huggingface.co/PrunaAI/P-Q-Image-2.1 - Generate or edit images in just 6 steps instead of 40. Use 6-steps for preserving inputs when editing and 6-steps-upsampled for improved visual quality and shorter end-to-end generation. - 6-step distillation provides improved quality with few generation steps. 6-steps-upsampled is the first distillation that removes the need for a separate prompt-upsampling step. This means 41 to 80 seconds saved, depending on your prompt style. - The LoRA adapters load directly on top of Qwen-Image-2.1, so the pipeline stays unchanged. Few-step distillation cuts the diffusion cost, and the upsampled adapter also removes the prompt-upsampling step before image generation.
