Stable Diffusion. It's free to download and use as you please, though it's a bitch to setup if you're unfamiliar, like I am, about how Git and Python works. And finding a damn download link for Stable Diffusion is also a bitch. None of which I can help with, it's been 2 years since I set it up and have completely forgotten, except how to launch it, how any of it works.
And you also require a good GPU and enough RAM. I'm using an RTX 3060, and have 16GB of RAM.
