    LCM-LoRA - Acceleration Module!


    Tested with ComfyUI, although I hear it's working with Auto1111 now!

    Step 1) Download LoRA

    Step 2) Add LoRA alongside any SDXL Model (or 1.5 model, if using the SD 1.5 version)

    Step 3) Set CFG to ~1.5 and Steps to 3

    Step 4) Generate images in ~<1 second (instantaneously on a 4090)

    Basic LCM Comfy workflow attached as "Training Images" in zip format.

    Could you make an Illustrious XL version?

    You probably figured that out, but you can use DMD 4step LoRA instead. I think there is even 1-step UNET version.

    @Mescalamba what do you mean? please elaborate, can you send the links? edit: nvm easily found in huggingface.co

    @Mescalamba The 1-step UNET version doesn't work, probably needs a specific inference script

    MescalambaOct 25, 2025

    @2P2 Ah, its quite possible, might be reason why its not used. Can look into it, eventually. Got bit too long TODO list tho.
