Unveiling Fooocus: Good for Beginners to start Stable Diffusion

Besides Automatic1111 and ComfyUI which often come up as the big names of interfaces for Stable Diffusion, Fooocus is another interface that’s super user-friendly for beginners.

What is Fooocus?

Fooocus is a cool piece of software that lets you use Stable Diffusion without needing the internet. It comes with a straightforward and user-friendly interface, totally free for anyone to use. With its roots in Gradio, Fooocus can create images with Stable Diffusion as easily as pie without sweating over technical stuff like sampling steps or CFG scale.

Pros and Cons of Fooocus

When it comes to using Fooocus, there are some clear advantages and disadvantages.


  • It’s super easy for anyone to start using, especially if you’re new and just want to create images.
  • It works quickly, giving you your images faster than many other options.
  • This tool allows those who don’t have top-of-the-line computers to use SDXL models without worrying about your computer’s memory.
  • Since it’s open-source and doesn’t cost anything, it’s a great choice to keep costs down in Stable Diffusion image generation.


  • Compared with other tools, it might not have as much freedom to tweak things exactly how you’d like them.
  • There are still limitations to its inpainting feature.
  • It can not install any extensions.
  • It’s not suitable for works that involve more intricate settings or configurations.

Mastering Fooocus: A Comprehensive Usage Guide

In this part, we’re going to take a closer look at how Fooocus works and check out all the cool stuff it can do. 

Install Fooocus in Your System

Fooocus can work on Windows, Mac, Linux, and even Google Colab. Here’s how to get Fooocus running on Windows:

  • First off, grab the download for Fooocus from Github.
  • Next up, unzip that file on your PC and then click the “run.bat” file to kick things off with Fooocus.
  • The first time you open it up, be patient because Fooocus needs to grab a checkpoint model from online. 
  • For those who have checkpoint models they want to use with Focoous just drop them in the Fooocs/models/checkpoints folder directory. 

Crafting Image Generation by Texting Prompts

When opening Fooocus, you only need to write a simple prompt and click the “Generate” button, and then Fooocus will give you an excellent output. With Fooocus, you don’t need to craft lengthy or overly complex prompts, as it handles the finer details like quality, aesthetics, and color for you.

Under the Input Image Checkbox

With Fooocus, when ticking the Input Image checkbox, you can upload your photo and do some neat stuff with it like making the quality better.

  • Image Upscale Tab: Upload your image and choose your upscale variation, like subtle, strong, 1.5x upscale, fast 2x upscale, and more.
  • Image Prompt Tab: Fooocus allows you to use an image as a prompt without installing any extractions. You can use ImagePrompt for image-to-image generation, PyraCanny for copying the poses of characters, CPDS for copying the 3D composition or depth of an image, and FaceSwap for swapping faces.
  • Inpaint or Outpaint Tab: With Inpainting, you can change any place in your image, and you can expand your image in whichever direction you choose with Outpainting.
  • Describe Tab: You have the ability called “image-to-prompt”, that you can turn the input image into prompts.

Exploring Advanced Features of Fooocus

Click the “Advanced” checkbox under the prompt field, you can control more over the images you generate.

Image Generation Settings Tab

In the Settings Tab on Fooocus, you can try the performance options like speed and quality based on your GPU and pick out the size and number of your picture. You can also use the “negative prompt” to change how your images come out.

Style Tab

In Fooocus, the Style Tab lets you pick various looks for making your images. It comes with a bunch of built-in styles like futuristic or retro that you can turn on or off right from the start. When hovering over these style choices, there’s a sneak peek showing what each style will make your image look like. 

Model Tab

In Fooocus, the Model Tab lets you pick a checkpoint model and add up to 5 LoRA models when making images. You get to choose from various models and decide how much each one should weigh in your project. On top of that, Fooocus supports SDXL models, which means that you can easily use SDXL without any technical problems. 

Advanced Tab

In Fooocus, there is an Advanced Tab for starters to set the Guidance Scale (CFG) and sharpness settings according to their needs. It’s pretty cool because it means every picture can be as crisp or as soft as you like.

How to Develop Stable Diffusion Software like Fooocus

Although Fooocus is easy to use for beginners in AI image generation, it has many limitations as mentioned before, like limited inpainting, simple workflow, and so on. How about developing a Stable Diffusion software better than it? If you get the hang of how stable diffusion works and are good at coding, it’s effortless for you to create one after getting relevant APIs. Here comes Novita AI, a powerful platform that features various APIs including AI image generation, image to prompt, and so on.
