LightDiffusion

The purpose of this repository and project is to remake the famous stable-diffusion in only one python script, with the least number of lines and in the least complex way. It’s made by retro-engineering Stable-Diffusion, ComfyUI and SDWebUI.

Features

• Original Txt2Img, Img2Img (R-ERSGAN4x+ UltimateSDUpscaling DPM++ 2M)
• Attention syntax
• Hires-Fix (euler ancestral normal)
• GPU only
• Xformers and Pytorch optimization
• Stable-Fast implementation offering a 70% speedup at the cost of pre inference model optimization windup time
• FP16 and FP32 precision support
• Saved state in between starts
• GUI
• DPM Adaptive Karras
• Clip Skip
• LoRa and textual inversion (embeddings) support

Installation

To install, please clone this repo and install the python dependencies by writing pip install -r requirements.txt

After doing that, add your SD1/1.5 safetensors model to the checkpoints directory and you should be good to go.

Stable-Fast

To use the stable-fast optimization refer to this guide to install from the wheel file.
