How to install Stable Diffusion WebUI AUTOMATIC1111 on Windows

WebUI Automatic1111 Stable Diffusion is a powerful tool that revolutionizes the way we create AI-generated images. It is a user-friendly interface that allows users to effortlessly run and manage their AI models for image generation.

What is Stable Diffusion WebUI Automatic1111?

Stable Diffusion, an open-source machine learning model, can generate images from text, modify images based on text, and enhance low-resolution or low-detail images. It has been trained on billions of images and can produce results that are on par with those generated by DALL-E 2 and MidJourney.

Automatic1111 is a web-based graphical user interface to run stable Diffusion. It brings up a webpage in your browser that provides the user interface. We will go through how to install the popular Stable Diffusion software AUTOMATIC1111 on Windows step-by-step. After this tutorial, you can generate AI images on your own PC.

Stable Diffusion WebUI Automatic1111 System Requirements

Windows 10, 11
Git, Conda, Python 3.10
16GB of RAM, 30G SSD Disk Space
Nvidia graphics card with at least 8GB of VRAM

Stable Diffusion WebUI AUTOMATIC1111 Installation Steps

Step 1. Install Chocolatey

Chocolatey is a machine-level, command-line package manager and installer for software on Microsoft Windows. We will use Chocolatey to install Git and Conda. First, open powershell.exe as an administrator and execute the following code:
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString(''))
powershell install chocolatey

Step 2. Install Git and Conda

Now we can easily use choco to install git and conda tools, please execute the following command line:
# install git
choco install git
# install conda
choco install anaconda3
Note: You can also install Git and Conda manually without choco.

Step 3. Download Stable Diffusion Repository

Download the stable-diffusion-webui repository as a .zip file, and then extract or use git to clone:
PS D:\github>git clone
Cloning into 'stable-diffusion-webui'...

Resolving deltas: 100% (13233/13233), done.
Note: Some files exceed multiple gigabytes, so make sure you have enough free space first.

Step 4. Create Stable Diffusion Running Environment

Open Anaconda Navigator, and create Stable Diffusion Env like below:
conda create python 3.10 env
Open StableDiffusion Env Terminal:
conda open python 3.10 env
Note: You can also install Python 3.10.11 manually without Anaconda. Newer versions of Python does not support torch. And remember to check "Add Python to PATH".

Step 5. Download Stable Diffusion Models

Models, sometimes called checkpoint files, are pre-trained Stable Diffusion weights intended for generating general or a particular genre of images. Go to CompVis or Stable Diffusion Art and download any model you like, for example, 1.5, and put it to models directory.

(StableDiffusion) D:\github\stable-diffusion-webui\models\Stable-diffusion\
download sd models

Step 6. Start Stable Diffusion WebUI Server

(StableDiffusion) D:\github\stable-diffusion-webui>webui.bat --xformers
venv "D:\github\stable-diffusion-webui\venv\Scripts\Python.exe"
