It's often said porn drives technology.

I clicked through the links in the article, since they sounded technically interesting. They led to AI-generated porn. Those, in turn, led to pages about training SD to generate porn. Now, two disclaimers:

1) I am not interested in AI-generating porn

2) I haven't followed SD in maybe 6-9 months

With those out-of-the-way, the out-of-the-box tools for fine-tuning SD are impressive, well beyond anything I've seen in the non-porn space, and the progress seems to be entirely driven by the anime porn community:

10 images is enough to fine-tune. 30-150 is preferred. This takes 15-240 minutes, depending on GPU. I do occasionally use SD for work. If this works for images other than naked and cartoon women, and for normal business graphics, this may dramatically increase the utility of SD in my workflows (at least if I get around to setting it up).

I want my images to have a consistent style. If I'm making icons, I'd like to fine-tune on my baseline icon set. If I'm making slides for a deck, I'd like those to have a consistent color scheme and visual language. Now I can.

Thanks creepy porn dudes!

The other piece: Anyone trying to keep the cat in the bag? It's too late.

> the progress seems to be entirely driven by the anime porn community:

Its not entirely driven by porn communities, and the porn communities driving it aren’t entirely anime porn communities (and the anime communities driving it aren’t entirely porn communities.)

But, yeah, the anime + porn/fetish art + furry + rpg art + scifi/fantasy art communities, and particularly the niches in the overlap of two or more of those are, pretty significant.

> If this works for images other than naked and cartoon women

It does, and while it may not be large proportionally compared to the anime-porn stuff, there’s a lot of publicly distributed fine tuned checkpoints, LoRas, etc., demonstrating that it does.

It absolutely works for things other than naked and cartoon women. Here are some generations of my daughter and dog (together!). I believe most of these are from a fine tuned model of them and not an extracted LoRA, though I use that sometimes too: https://imgur.com/a/naHgnel

The space one without headphones is particularly cool.

I use it for D&D art generation. I can have a piece of art that somewhat matches every location/scene I have planned. If things don't match my plans I can generate 8 images and pick the best in about 2 minutes. I talk to a lot of other DMs who use it in a similar way.

It's not great with specific details, I plan to commission someone to draw the party when the campaign is over. But for things like a fantasy magic shop with potions, or a fantasy dungeon exterior, or a forest of mushroom trees, it's more than good enough for concept art to throw into Roll20. I couldn't afford 5-10 pieces of custom concept art per game, nor could I come up with the ideas for them 2 hours beforehand and have them ready for the session.

Have you tried XL as a test for handling specific details?

I have not and will try it soon now that it's out in an official release. But I doubt it can meet the level of detail my players have put into their own characters. I also fully expect to need to pay for revisions from whatever artist I commission. But I really want a piece of art that every player feels captures their character perfectly.

I will choose to intentionally misread that :)
