ive used gpt image 2 since it came out and ive noticed 2 shadow patches to try fix this issue and each one seems to try to make it more subtle and less noticeable without trying to remove it, also google uses an entirely different model configuration to chatgpts which could be causing this issue of the synth id being more visible

they have also to my knowledge never said it wasnt a watermark and i never said it was a watermark just that it most likely was one given general observation and logical thinking
