Does AI image generation struggle with high resolutions or is that just a choice for web friendliness?

I was thinking maybe the limited resolution of these tools is to hide blemishes. I'd really like ultra high resolution versions of some of these.

Some of the pics I uploaded actually came out looking pretty rad. Would definitely find a use for them somewhere.

The "How", "Why", and "Who" links aren't working for me. Are they working for anyone else?

Usually higher resolution will require significantly more GPU memory.

The whole site seems to be down for me right now. EDIT: Just really slow. Seems to be overloaded.

It loads but very slow. Most of them seem to be from the MIT IBM Watson AI Lab. I like that they used generated portraits of themself :D

Extract of "Why":

"AI Portraits Ars uses Artificial Intelligence to reproduce artistic human portraits, with different styles and levels of abstraction. For our model training, we adopt a data set of tens of thousands of paintings from the Early Renaissance to Contemporary Art. This type of portraiture is quite distinctive of the Western artistic tradition. Training our models on a data set with such strong bias leads us to reflect on the importance of AI fairness. In the previous work AI Portraits Celebrity, we explored the concept of micro-bias linked to the training data of only actors, which in some way imposes an actorization of the user's portrait: “a collection of faces from the society of spectacle that are sedimented in the neural network, and vaporize my selfie in a cinematographic self." AI Portraits Ars introduces a very different type of bias with unique themes to explore."

In case you want to sign-up and cannot get the client side validation to accept your password: they apply email validation to the passwords. You'll have to make up a password that's also a valid email address. In other words, something like: aBqwdHkjh@oqwIrd.com

Traditionally, GANs have. It wasn’t really possible to make high quality, high resolution GAN output until ~last year when researchers discovered how to progressively grow them from smaller resolution ones.
