Stable Diffusion Tutorial: Prototyping with the Web UI

What is Stable Diffusion?

Stable Diffusion is a groundbreaking deep learning, text-to-image diffusion model introduced in 2022. This innovative technology is designed primarily for generating images based on text descriptions, enabling users to turn their written ideas into vivid visual representations. Beyond generating images, Stable Diffusion also supports various tasks including inpainting, outpainting, and image-to-image translation guided by text prompts, making it a versatile tool in the world of artificial intelligence.

How to Use Stable Diffusion Web UI Locally

For those looking to test the model locally, the GitHub user AUTOMATIC1111 has developed a Stable Diffusion Web Interface that allows users to run experiments in a user-friendly environment. This Web UI is built utilizing Gradio, a Python library that facilitates the creation of UI components.

Features of the Web Interface

• Original txt2img and img2img modes
• One-click install and run script (requiring installation of Python and Git)
• Outpainting
• Inpainting
• Color Sketch
• Prompt Matrix
• Stable Diffusion Upscale
• Ability to specify parts of text for the model to focus on
• Extras Tab including:
  • GFPGAN: Facial restoration neural network
  • CodeFormer: An alternative face restoration tool
  • RealESRGAN: Neural network upscaler
  • ESRGAN: Advanced upscaling options
  • SwinIR and Swin2SR: Advanced upscalers
  • LDSR: Latent diffusion super-resolution
• Various resizing aspect ratio options
• Random Artist Button: Generates images in the style of random artists
• Styles: Save and apply parts of prompts easily
• Variations: Generate similar images with slight differences

How to Use the Web Interface

For Windows Users

1. Download and install Python 3.10.6, making sure to check "Add Python to PATH" during installation.
2. Install Git.
3. Clone the repository by running the command: git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui.git.
4. Place model.ckpt in the models directory (refer to dependencies for model source).
5. (Optional) Place GFPGANv1.4.pth in the base directory next to webui.py.
6. Run webui-user.bat from the Windows Explorer as a regular user (non-administrator).

For Linux Users

To install in /home/$(whoami)/stable-diffusion-webui/, use the appropriate commands for your distribution to handle the dependencies.

For Apple Silicon Users

Instructions and compatibility details can be found in the official documentation links provided on the GitHub repository.
