Unlock your creativity on Windows with Stable Diffusion. Install and harness the power of this remarkable tool to effortlessly generate stunning images. Explore installation and usage instructions now!

1. Introduction

Today we are going to look at how you can both install and use Stable Diffusion. With Stable Diffusion, you can type in some text, and then using AI, you can generate an image based on that text, and the results are actually really stunning. There are many different companies pushing out technology like this, but the reason I like Stable Diffusion so much is, first off, the code is public and also free to use. You can install it on your computer as long as you have a decent graphics card, and you also get full rights to all of the images that are generated. Let's check this out.

2. Preparing Your PC for Stable Diffusion

First, we want to make sure that your PC is even capable of running Stable Diffusion, and you'll want to make sure that you have a discrete GPU (graphics card).

  • On Windows, press Control + Shift + Escape to open Task Manager.
  • Click on "Performance" on the left-hand side.

Now look if you have the following requirements:

  • At least a dedicated graphics card like NVIDIA.
  • At least 4 GB of dedicated GPU memory.
  • At least 10 GB of free hard drive space.

If you meet these requirements, you're ready to move on to the installation process.

7. Additional Settings

By default, your version of Stable Diffusion will not receive automatic updates. Considering the rapid pace of advancements, it is highly probable that you will need to update your version at some stage in order to access the most up-to-date and impressive features. This can be achieved by adding the line git pull to the top of the webui-user.bat file.

Additionally you can speed up stable diffusion with some additional settings. If you have less than 8 GB VRAM on GPU, it is a good idea to turn on the --medvram option to save memory to generate more images at a time.

To enable these settings, right-click on the file webui-user.bat and select Edit. (You may need to select “Show More Options” first if you use Windows 11).

  • When opened add git pull to the top of the document. This will automatically update to the newest version when starting Stable Diffusion.
  • Update COMMANDLINE_ARGS to the following: set COMMANDLINE_ARGS= --xformers --medvram
  • Save, Close and Double Click the file to start Stable Diffusion with these new settings.

Do you get out-of-memory errors?

  • Consider changing the --medvram settings to --lowvram.
  • Additionally, Add a new line in the webui-user.bat file named set PYTORCH_CUDA_ALLOC_CONF.
  • Set the value to garbage_collection_threshold:0.6,max_split_size_mb:128
