Automatic1111 is the most popular open-source web interface for running Stable Diffusion image generation. A GPU-enabled Breeze makes it easy to generate AI artwork privately.

System Requirements

A Breeze with a dedicated GPU (8 GB+ VRAM recommended)
Ubuntu 22.04 or later
At least 20 GB free disk space for models

Install Prerequisites

sudo apt update && sudo apt install -y git python3 python3-venv python3-pip wget
sudo apt install -y libgl1 libglib2.0-0

Clone and Launch

cd /opt
git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui.git
cd stable-diffusion-webui
python3 -m venv venv
source venv/bin/activate
bash webui.sh --listen --port 7860

The --listen flag allows access from external IPs. Use a reverse proxy with authentication for production.

Download Models

Place Stable Diffusion checkpoint files in the models directory:

cd /opt/stable-diffusion-webui/models/Stable-diffusion
wget https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors

Running as a Service

Create a systemd unit so the WebUI starts on boot:

sudo tee /etc/systemd/system/sd-webui.service <<EOF
[Unit]
Description=Stable Diffusion WebUI
After=network.target

[Service]
User=sduser
WorkingDirectory=/opt/stable-diffusion-webui
ExecStart=/opt/stable-diffusion-webui/venv/bin/python launch.py --listen --port 7860
Restart=always
