Check If Your Computer Can Run Stable Diffusion XL
The first step is to check if your computer meets the system requirements to run Stable Diffusion XL smoothly. You'll need a decent GPU with at least 8GB of VRAM for reasonable performance. To check your GPU and VRAM, open Task Manager in Windows and look under the Performance tab.
If you don't have 8GB of VRAM, you may still be able to run Stable Diffusion XL using your CPU instead of GPU. However, generation will be much slower - up to 30 minutes per image. Running on CPU is only recommended for testing purposes if you lack the GPU requirements.
Use Task Manager to Check GPU and VRAM
Hold down the Windows key and press X to open the power user menu. Click on Task Manager. Go to the Performance tab. Look for your GPU and check the dedicated GPU memory, which shows your VRAM. You need at least 8GB for a good experience.
Minimum 8GB VRAM Recommended
For smooth performance with Stable Diffusion XL, your GPU should have at least 8GB of VRAM based on community feedback. More VRAM allows you to generate higher resolution images faster.
CPU Mode Alternative for Low-End Systems
If your system doesn't have a capable GPU, Stable Diffusion XL can run in CPU mode. This uses your CPU for generation instead of GPU. However, it's much slower - taking up to 30 minutes per image. CPU mode allows low-end machines to test and use the AI.
Download Stable Diffusion XL and Comfy UI
The next step is to download the Stable Diffusion XL model file and Comfy UI. Comfy UI is an open source app that provides an interface for generating images with Stable Diffusion. Links to download both files are in the video description.
The Stable Diffusion XL file is around 6GB and Comfy UI is 1.4GB, so make sure you have decent internet speeds to download these large files reasonably quickly. They are hosted on reputable sites for open source AI content.
Install 7-Zip to Extract Comfy UI
Comfy UI downloads as a zip file, so you need to extract it before use. A free app called 7-Zip allows you to easily extract zip files. Download and install 7-Zip, then right click the Comfy UI zip file, choose 7-Zip file manager, and extract it to a location like your desktop for easy access.
Locate Checkpoints Folder in Comfy UI
Inside the extracted Comfy UI folder is a checkpoints folder. This is where you will later move your Stable Diffusion XL model file so Comfy UI can access it.
Move Stable Diffusion Checkpoint File
Now navigate back to your downloads folder and locate the Stable Diffusion XL file you downloaded earlier. Move this file into the checkpoints folder inside Comfy UI. This transfers the model file to where Comfy UI expects it.
Launch Comfy UI and Generate Images
Understand Comfy UI Interface
Double click the 'run Nvidia gpu' file inside Comfy UI to launch it. This opens the web app interface. The main sections are prompt fields to describe the image to generate on the left, advanced settings in the middle, and the generation button on the right.
Customize Settings as Needed
You can tweak settings like image dimensions in the middle column. Default settings work well for starting out. The Stable Diffusion XL model you downloaded earlier should show as the loaded checkpoint.
Hit Generate and View Outputs
Type a text prompt describing the image you want to create, then press Generate. Once it finishes, find the output images in Comfy UI's output folder to view and save creations. Enjoy exploring what Stable Diffusion XL can design!
