"SPIN-Diffusion generates images with superior visual appeal than previous fine-tuning methods"

It's sort of like DPO, since it has been trained on human-preferred aesthetic images. Or can be used like a detail enhancer.

I'm still experimenting with it what it can do, but have provided a few different sizes of LoRA to play with. You can try it with different weighting for variety, or just stick with 1.0.

FYI Clip weight LoRA parameter will have no effect, since this was trained on the U-Net model only

The original model can be found here: https://huggingface.co/UCLA-AGI/SPIN-Diffusion-iter3. I merged the U-Net weights with SD 1.5 base and extracted into some LoRAs of varying dimension. reprinted from: https://huggingface.co/otterpupp/spin-diffusion-v3-sd15/tree/main/loras
