-This repository contains offset versions of https://huggingface.co/mhdang/dpo-sdxl-text2image-v1 and https://huggingface.co/mhdang/dpo-sd1.5-text2image-v1.
+
+# Contents
+
+This repository contains:
+1. Half-Precision LoRA versions of https://huggingface.co/mhdang/dpo-sdxl-text2image-v1 and https://huggingface.co/mhdang/dpo-sd1.5-text2image-v1.
+2. Full-Precision offset versions of https://huggingface.co/mhdang/dpo-sdxl-text2image-v1 and https://huggingface.co/mhdang/dpo-sd1.5-text2image-v1.
+
+# Creation
+
+## LoRA
+
+The LoRA were created using Kohya SS.
+
+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.safetensors
+
+## Offsets
+
+The offsets were calculated in Pytorch using the following formula:
+
+1.5: https://huggingface.co/mhdang/dpo-sd1.5-text2image-v1/blob/main/unet/diffusion_pytorch_model.safetensors - https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/unet/diffusion_pytorch_model.bin
+XL: https://huggingface.co/mhdang/dpo-sdxl-text2image-v1/blob/main/unet/diffusion_pytorch_model.safetensors - https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/unet/diffusion_pytorch_model.safetensors
 
 These can be added directly to any initialized UNet to inject DPO training into it. See the code below for usage (diffusers only.)
