I couldn't find the DMD2 LoRA on Civitai, so I copied it from https://huggingface.co/tianweiy/DMD2 . It is similar to the LCM-LoRA and Lightning-LoRA in that it accelerates image generation while approximately preserving quality. Apparently DMD2 must be used with the LCM scheduler and CFG 1.0 (can't handle CFG > 1.0). Steps should be 4, but slightly more seems to improve the quality. The absence of CFG (my guess) means that prompt adherence is not perfect.
