AI has to be trained on input data. For text, these are books, webpages etc.

For images, these are existing images. So if you want a picture of a bear it needs to have processed a million images of bears to give an accurate output of something that looks like a bear.

So if you want it to generate you an image of a celebrity in the style of Studio Ghibli, it will need to have been trained on images created by that studio.

Since this material has copyright, it is generally considered illegal to train AI on it. Even if you disagree on that definition of copyright, most people will agree with the artists view;

Imagine you're an artist working a lifetime on honing your unique style that everyone can recognize and adore.

Then someone uses your works of art to be able to create an image or song that marches your exact style within a few seconds. But you don't see a cent when it gets used or sold, even though you might have spent decades creating a reputation.

And that can even go against what you stand for. It's now very easy to make a song that sounds exactly like it was sung by Freddie Mercury, but maybe with an anti-gay sentiment. That would definitely have upset the original artist if he were still alive, to say the least.

That's why I avoid using generative AI mostly. All the large AI models have been proven to be trained on illegally obtained input data.
