I'm pretty sure that the way they constantly fuck up hands is a solid demonstration that these AI tools do not have a perfect recollection
The reason they fuck up hands is because hands are usually moving during pictures and have many different configurations compared to any other body part.
So when these image AIs refer back to all the pictures of hands they’ve been fed and use them to create an ‘average approximation’ of what a hand looks like they include the motion blur from some of their samples, a middle finger sticking up from another sample or extra fingers from the sample pictures of people holding hands etc and mismatch them together even when it doesn’t fit in the picture being created.
The AI doesn’t know what a hand is. It is just mixing together samples from its perfect recollection.
What? No
How many pictures do you see online where the hands are in motion, or even blurred?
Hands are usually behind objects when they hold something and can indeed have tons of variations and configurations. Even human artists fuck up all the time or just not draw them at all.
AI don't combine samples. If they did they wouldn't be able to generate new pictures of whatever subject you want in a specific style you want and then have multiple variations of that picture.
It isn't a copy and paste, it is interpreting the drawing and modifying it based upon the prompt.
