I know the filters you're talking about, and they can certainly turn photos into some faux-artistic effects, but the result is really bad, and everything in the image remains in the exact same place.
This is applying an actual artistic style, and also changing body position, background, hair, lighting, etc.
So I don't know why you'd want to be so dismissive of something like this.
Not sure the power costs of running a model like this over the caloric costs of a human + the power to power their photoshop machine, for instance, is worth it.
Saying they look the same is like saying Nintendo 64 graphics look the same as PlayStation 5 graphics. It's just incorrect.
How many magazine covers do you see and actually believe that was anything close to what the original image looked like? I have no idea how long this thing takes, but I'm guessing it's helluva lot faster than a person in PS, and it will be doable with anybody with zero amount of talent required.
To think it couldn't be done in PS is just lack of knowing good PS artists.
Your interpretation of the original comment into saying it was simple is a bit skewed
You can also do much the same with imagemagic, no AI required.
