So HN, any theories on how this happened ?

They used a circular mask and the model overfitted on Bitcoins as likely examples of circles? Adobe's models are only trained on their stock image library and they have a whopping 646,136 Bitcoin images. https://stock.adobe.com/search?k=Bitcoin https://stock.adobe.com/search?k=Bitcoin

  that seems like too many

    Correction, they have nearly a million Bitcoin images once you unfilter the ones tagged as AI generated, which are hidden by default. I assume they don't train their models on those though.

  All of them AI slop of course. They train on this? I guess it's garbage in, garbage out.

Seems like they used some AI tool to remove speckles from an image. The tool has to generate a likely replacement. And one of the speckles looked a bit like a coin.

  That's the bit that puzzles me the most though: you want that bit gone, so why would it fill in what that shimmer looks like? If there's an airplane in the sky that you want gone from a medieval movie frame, so you select the airplane and select "remove", surely it doesn't fill in an airplane because that's the closest match for what's being selected? I must be missing something obvious but I don't see it mentioned in the submission or comments, or perhaps I'm not making the connection

    What does gone mean though? You aren’t just drawing a black or transparent spot underneath what you want removed. You’re filling it in with the most likely background. Which is not a trivial operation. It’s an AI generative fill which is obviously unpredictable. You’d expect it to generate ocean but it drew a bitcoin. That’s just how AI generative fill works. You keep running it until it looks how you want.

      > What does gone mean though? Anything but the original. That the original might have shimmered (or otherwise looked like) this Bitcoin icon, should have no bearing on what it chooses to put there

  Your explanation could make sense for TFA, but definitely not in the case below https://www.reddit.com/r/photoshop/comments/1e5nyt7/generative_ai_suggesting_bitcoin/ https://www.reddit.com/r/photoshop/comments/1e5nyt7/generati...

Maybe cryptobros with zero skills and no talent created too much images copy-pasting the same bitcoin image over everything, which caused poisoning of training data. I also expect some bug involved, where user selects a circular mask, but outer edge is slightly blurred (feathered), which, when multiplied with white background, gives a light circle-shaped contour. After that Photoshop fills not a "hole in the sky", but a "light circle-shaped object" in the sky.
