Stable Diffusion, running the model "Realistic Vision 2.0".
Discussion
I've thought about getting stable diffusion
Never played around with it myself, but from what I hear it is best if you can run it locally, especially if you are planning to use it for generating NSFW content. Requires a relatively beefy GPU though.
The folks generating this content over on r/unstable_diffusion on Reddit are very helpful and often post tutorials about their workflow for how they achieved these results.
That's cool. One of the things I don't like about midjourney is its ban on anything "sexual" involving women.
And I'm not talking about full nudes, I just sometimes want a character in a bikini or with larger breaststroke, but no, gully clothed B cup is as good as it gets. Buy for men, oh, shirtless barbarians with rippling muscles in nothing but a cod piece is fine.
Yes, midjourney is very locked down. As with most things, if you want liberty to do whatever you want, then self-hosted is the way to go.
