That's pretty easily fixable if you train a LoRA or similar so that the model has a specific likeness in mind. (You can look at - and despair at - Civitai if you want proof.) It's harder to do at inference time without training, but I wouldn't assume it'll be impossible forever, especially with the existence of ControlNet.

This is a GAN, so you can just project the image of yourself into the latent space (which will give you a near-pixel-perfect reconstruction), fix the identity-relevant variables in the _z_, and edit it as necessary. (No workarounds like finetuning necessary. Just one of the many forgotten advantages of GANs.)

>fix the identity-relevant variables in the _z_

Is that how the latent space works though; Like if it's a 300-dim vector, is the face at locations 0-10?

Looking at the poses, it feels optimized for generating porn, but one example someone showed had a child's face (good god please don't let your "AI" system generate child anything if you want to sell it for porn purposes), and another user noted that their attempt error'd out because it "detected nudity", even though other users get given a nude model by default.

As something you generate in a photorealistic image generator you are building a business around?

The fact that it is a serious crime in many jurisdictions and, even where it isn’t, photorealistic child porn images that get noticed anywhere or going to result in uncomfortable conversations for everyone involved in the process of establishing that they aren’t evidence of a crime.

I always thought peak of popular culture had a bit of a negative effect on the body image of the rest. Now we’re going to let ai define the ideals… this might be slippery.

"Now"? I doubt everyone is going to want to have six mangled fingers on one hand and a claw on the other.

Okay, agreed. I ran about 15-20 gens through the site, got mangled feet/legs, disconnected appendages, extra appendages, nudity, nudity imprinted onto clothing, just bizarre stuff.

Tomorrow's "Now", maybe.

I get that most of these are hilarious (this is my favorite comment on HN in some time, https://news.ycombinator.com/item?id=37239909 ). But still, I find this incredibly frightening. These are only going to get better. Does anyone doubt that in a couple years time (if that) we'll be able to put the image of any known public person into whatever generated photo we want, which would be indistinguishable from reality?…

I think already a thing?

Some will surely consider that a feature rather than a bug.

But then how am I supposed to be the kind of creepy person that jerks it to poorly modified "nudes" made from Facebook profile pics?

We're basically there right now betweem Deepnude[1] and Photoshop. [1] (NSFW, seriously.) https://deepnude.cc/

Not sure if these should have light brought upon them or stay under rocks.

If you're wondering how it's so fast and cheap and they can generate variants so easily, it's because they're using GANs (see the footer). GANs are way faster than diffusion models because they generate the image in a single forward pass and their true latent space encoding makes editing a breeze. (And if you're wondering how it can look so good when 'everyone knows GANs don't work because they're too unstable', a wi…

While there's discussion on the topic here - are there any resources that can explain the exact mechanism of how a GAN works for image generation? I have a rough idea of how diffusion models work, but I'm still no AI researcher.

To expand on what I take as your implied argument- Some (small) percentage of people are pedophiles, meaning they're attracted to children. Presumably they can't help that, just as others can't change their sexual preferences. Clearly acting on this urge with an actual child is wrong. That's true whether it's directly assaulting a child, or consuming child porn, as that market encourages others to exploit children to generate it. However, if it is possible to produce CP without involving actual children, it could provide an outlet for those desires that would reduce demand for actual CP, and thereby reduce incidents of children being abused to produce it.

One could argue that such an outlet could even reduce incidents of direct sexual assault of children by pedophiles, but there is also a counter-argument that it would instead serve to "whet the appetite" and encourage such behaviour. And of course there are other counter-arguments; it could make actual CP more difficult to detect, for one. Finally there is the argument from the perspective of fundamental morality, that depicting children in a sexual manner is wrong in and of itself, and therefore the various potential effects are irrelevant. (Much like it's wrong to murder an innocent, even if you could harvest their organs and save five others as a result.)
