I think it's interesting that AI is probably unintuitively good at spotting fraud in papers due to their ability to hold more context than majority of humans. I wish someone explored this to see if it can spot academic fraud that isn't in their training data already.
It sounds like it's better at putting the fraud into science than at getting it out
LLM's still make stuff up routinely about things like this so no there's no way this is a reliable method.
