Automatic1111's webui is what 90% of the StableDiffusion community uses but he recently made the decision to use a company's proprietary code after it was leaked by a hacker and when confronted about it, instead of removing it as requested he chose to lie about it despite the git history evidence and the fact that the paper he claimed to have used as reference wasn't related at all to the techniques used by the stolen code.

The company whose code was stolen works closely with the man behind SD and the decision was made to merely ban him from the community instead of torpedo-ing the repo via DMCA.

This seems to have been proven to not be the case, and the code in-fact originates from a pre-stable-diffusion MIT licensed repo.

It's not even a particularly large or interesting piece of code, the only reason why it's controvertial is because of the code is only necessary to use the NovelAI leaked models.

I'd be interested to see that repo since one of the commits to Automatic's github is Anlatan's code while a second commit changes function names and tweaks the code slightly in an apparent effort to disguise it's origin. Most of the discussion about this has been on 4chan where the amounts of misinformation has been staggering before it pretty much devolved into "it doesn't matter if their code was taken, it should have been open source anyway".

This is what other people have found over on reddit: https://reddit.com/r/StableDiffusion/comments/xzipjx/automat... According to that comment, this (https://user-images.githubusercontent.com/23345188/194727572...) is allegedly the only reasonable match with the leaked code from NovelAI, but note that I have not verified that myself, and since NovelAI/Stability never said which part they take issue with it is hard to tell. This is the file in that other repo that the code actually seems to originate from https://github.com/lucidrains/perceiver-pytorch/blame/main/p...

As you can see, that repo from 2 years ago even originates the "# attention, what we cannot get enough of" comment and is an exact 1:1 match to Automatics commit, while the one from NovelAI even has a small change in the if clause that Automatic doesn't have.

The code that was taken from Anlatan is actually this: https://user-images.githubusercontent.com/23345188/194727441... But that same GitHub issue also shows code from the lucidrains repo (the picture you've linked there) and people have latched onto it saying nothing was taken when the picture I linked is right above it containing code that doesn't exist outside the leaked code and Automatic's fork.
