Like the rest of the world, I've been playing around with AI generated art. In my case, I've been using Stable Diffusion UI. Stable Diffusion UI is an easy to install and use variation of Stable Diffusion that also includes a GUI. I was able to get running on both Windows and Linux without much effort. The easy install was what appealed to me the most though I have been using the GUI as well.
To get speedy results you need a decent GPU. However, you don't need a GPU at all to use Stable Diffusion UI as long as you have patience. If you don't have a GPU and use only the CPU, each image will take a much longer time to produce. It can take thirty minutes or more depending on your hardware and the settings you use. However, this is open source software so you can generate as many images as you want without worrying about signing up for anything or paying a subscription fee. The end result is that even with limited hardware, you can still produce unlimited images as long as you are patient.
This is another steampunk themed portrait that I think came out pretty well. However, it is also an image where the steampunk theme isn't necessarily obvious. I mean the artificial arm is pretty obvious but at a glance you might think more modern robotic vs. an age of steam design.
