This has been obvious for a while to those of us using GitHub Copilot for programming. Start a function, and then just keep hitting tab to let it autotype based on what it already wrote. It quickly devolves into strange and random bullshit. You gotta babysit it.

Same thing with Stable Diffusion if you've ever used a generated image as an input and repeated the same prompt. You basically get a deep-fried copy.

img2img is not "training" the model. Completely different process.

Oh yeah, you're right. It's both degradation in some way, but through entirely different causes.
