DPO (Direct Preference Optimization) LoRA for XL and 1.5 OpenRail++

__html__What is DPO?DPO is Direct Preference Optimization, the name given to the process whereby a diffusion model is finetuned based on human-chosen images. Meihua Dang et. al. have trained Stable Diffusion 1.5 and Stable Diffusion XL using this method and the Pick-a-Pic v2 Dataset, which can be found at https://huggingface.co/datasets/yuvalkirstain/pickapic_v2, and wrote a paper about it at https://huggingface.co/papers/2311.12908.What does it Do?The trained DPO models have been observed to produce higher quality images than their untuned counterparts, with a significant emphasis on the…__html__What is DPO?DPO is Direct Preference Optimization, the name given to the process whereby a diffusion model is finetuned based on human-chosen images.

These LoRA can bring that prompt adherence to other fine-tuned Stable Diffusion models.Who Trained This?These LoRA are based on the works of Meihua Dang (https://huggingface.co/mhdang) athttps://huggingface.co/mhdang/dpo-sdxl-text2image-v1 and https://huggingface.co/mhdang/dpo-sd1.5-text2image-v1, licensed under OpenRail++.How were these LoRA Made?They were created using Kohya SS by extracting them from other OpenRail++ licensed checkpoints on CivitAI and HuggingFace.1.5: https://civitai.com/models/240850/sd15-direct-preference-optimization-dpo extracted from https://huggingface.co/fp16-guy/Stable-Diffusion-v1-5_fp16_cleaned/blob/main/sd_1.5.safetensors.XL: https://civitai.com/models/238319/sd-xl-dpo-finetune-direct-preference-optimization extracted from https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/sd_xl_base_1.0_0.9vae.safeنمایش بیشتر
