Yes! There is a model called ACE++ from Alibaba that is specifically trained to replace masked areas with a reference image. We use it in https://phind.design. It does seem like a very esoteric and uncommon task though.

I don't think it is that esoteric, that sounds like deepfake 101. If you don't mind answering, does Phind do anything to prevent / mitigate this?

Oh cool thanks I haven't come across that one, I'll give it a shot.
