Like everybody else on the planet (or so it seems), I've started playing around with AI generated art. In my case, I downloaded Stable Diffusion and have been playing around with that. In particular, I have been using an easy to install version called Stable Diffusion UI that I was able to get running on both Windows and Linux. It has a GUI which some people might prefer (and I have been using) but the real appeal to me was that it was easy to install.
Stable Diffusion seems to work, within limits, on nVidia GPUs with 4MB or more. I have seen minimum requirements listed as higher than that but as long as you stick with 512x512 or smaller images and disable the "Turbo" option it seems to work pretty well. Also, you don't technically even need a GPU to use Stable Diffusion. It's just that if you don't have one and use only the CPU, each image will take 30 minutes or more to produce (depending on how fast your CPU is). However, this is open source software so you can generate as many images as you want for free, even with limited hardware...as long as you are patient.
"Cyberpunk" was one of the various themes for which I tried generating images. This was one of my first attempts. Most cyberpunk images seem to be dark and gritty but this one came out much different. It reminds me somewhat of an early 1990s aesthetic when the first wave of VR devices started showing up in places like arcades. Anybody remember Lawnmower Man? Anyway, I liked the sort of neon aesthetic of this.
