Brief of automatic1111

Automatic1111 is an open-source project that refers to a web-based GUI built on top of the Stable Diffusion AI image generation model. We also call it Stable Diffusion WebUI or A1111.

It's a browser interface based on Gradio library for stable diffusion and It provides a user-friendly interface for users to:

  1. Generate images from text prompt (txt2img)
  2. Edit and improve existing images (img2img)
  3. Other advanced features such as model training etc

This guide will provide step-by-step instructions on how to install Stable Diffusion Web UI, along with helpful tips that cover basic usage.

You are all set

When you see this page in your browser, it means that all the environments are ready.

  • Section 1: Indicate what checkpoint you are using right now.
  • Section 2: Simply input your prompt and negative prompt and let the tool generate images for you.
  • Section 3: The area for modifying image generation parameters such as image dimensions, batch size, sampling steps, etc.
  • Section 4: The generated images will be displayed in this area.

I will talk a little bit more about how to tune with different parameters and how to optimize in the next article.
