Do not use it anymore, we will remove it soon. A1111 is not updated by its developer since over a year now. It will not work wit newer Drivers, GPUs and so on. Also its full of issues and still does not support newer Models. Read more here: https://github.com/AUTOMATIC1111/stable-diffusion-webui Working driver is: nvidia-driver-550-server
Oldie but goldie. With A1111 you can create images from Base Stable Diffusion and SDXL. Modify them or create 1000 of images of a single prompt. Also you can install great mods to train image models based on SDXL effectively.
