AI 导读

PrunaAI 在 Hugging Face 发布 P-Q-Image-2.1 的 6 步 LoRA 适配器，把图像生成或编辑从 40 步降到 6 步。其中 6-steps-upsampled 版本去掉了单独的提示词上采样步骤，按提示词风格可节省 41 到 80 秒。适配器直接加载在 Qwen-Image-2.1 之上，原有流程无需改动。

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.
