I didnt tried but only an assumption but, something I come across before. With using stable diffusion, it creates metadata as well, but with using its extra feature (increasing image resolution), it gets rid of the metadata (at least, with the tools I used, they dont see it), so with creating an image with GPT and using this kind of method might get rid of the metadata as well.
Again, I didnt tried and only an assumption.
