What's really amazing to me is the rendering quality, if that's the right word for it, the resolution. This seems different to me than the "structural realism" in the sense of how plausible the face is in it being representative. Not sure if there are terms for this but it's amazing to me how realistic things like skin texture are independent of "higher level" features.

I'm intrigued about the possibility of using these as stock photos - it dies away with the need for model permissions (or does it?). Presumably the copyright on the image resides with the person who ... programmed the neural net? Trained the neural net? Is running the server?

>I'm intrigued about the possibility of using these as stock photos Another (darker) possibility is to generate copyrighted images. Once you have (say) a trillion photos, it will be hard to generate a new one that doesn't look (in essence) like one you already have.

Copyright doesn't work that way: "copyrights can only be infringed if the infringer has access to the copyrighted work and engages in actual copying of the work" https://www.trademarkwise.com/blog/2015/2/4/copyright-infrin..., https://en.wikipedia.org/wiki/Substantial_similarity

An artist friend of mine is using this technology in an interesting way .. she's drawing regular street portraits of people she meets, and then using that as the seed to generate new pictures of people who do not exist. It has produced some extraordinarily disturbing art, especially for those of us who were her subjects. Some of the images are so wild and out there, it really is an adventure into ones own psyche. I s…

Does she have any online, on DeviantArt or Instagram or something?

I have a question - When generating a new person (or whatever it is that does not exist) can you know that it isn’t like any of the images that went into the training data set? How likely is it for it to actually exist after all?

The model has 18x512 parameters, and all 9000 parameters are 32-bit floats. Even assuming only 16 bits of randomness for each parameter (to keep them small enough, so you don't get too wild, because the center of 0 is a pretty homogenized face), 16^9000 is a lot of permuations of faces. They will, of course, borrow from all of the 70k faces on Flickr that power StyleGAN, in varying degrees.

Could it by chance recreate on an input image though?

Is it not possible, or just incredibly unlikely?

I also wonder how similar to an original person it needs to be before you would believe it's them anyway.

Here’s the Guardian article which linked the site: https://www.theguardian.com/culture/2020/feb/07/ai-in-the-ad... To my mind there is a massive need for us in the software world to pause and think about the ethics of all of this. Engineers more broadly have well developed ethical codes, we should too.

So are you saying software developers should have to take the equivalent of a Bar exam in order to practice software development in a given state? That way ethical code violations have teeth because you can be debarred.

As of now anyone and their dog can practice software development and I'm not sure what a nebulous "ethical code" would imply for them.

It has been interesting to see images clearly generated by this service (same artefacts, same resolution) start to flood online dating apps and social media profiles. Previously, fake accounts tended to use photos which could be reverse-image-searched to detect them.

Luckily, it doesn't seem that this approach can be sensibly extended to generate entire scenes, or multiple entire-body photos from different angles. Believability breaks down tremendously in less constrained datasets- see https://www.thiscatdoesnotexist.com for example.
