LCM/LCM-LoRA

• Download LCM-LoRA form https://huggingface.co/latent-consistency/lcm-lora-sdv1-5
• Specify LCM-LoRA by adding <lora:lcm-lora-sdv1-5:1> to prompt
• It's advisable to set --cfg-scale to 1.0 instead of the default 7.0. For --steps, a range of 2-8 steps is recommended. For --sampling-method, lcm/euler_a is recommended.

Here's a simple example:

./bin/sd -m ../models/v1-5-pruned-emaonly.safetensors -p "a lovely cat<lora:lcm-lora-sdv1-5:1>" --steps 4 --lora-model-dir ../models -v --cfg-scale 1

without LCM-LoRA (--cfg-scale 7)	with LCM-LoRA (--cfg-scale 1)
