I mean, it does mistake Frank Sinatra for Louis Armstrong -- I guess it makes errors. But it just refuses to process my img2img images. It breaks down. Why?
It made me so agitated I made a gallery[0]. Granted, some of those images are strange, but others are just normal people doing normal things.
img2img creations are probably confusing it because they are totally rearranging how the prompt emerges from what's in the latent space with respect to a new image. So if you make an image of <subject> by passing in an image of <subject>, it's going to represent <subject> in a fundamentally different way than if it relies purely on its own "imagination" for the rendition.
