AI detectors aren’t trained by gradient descent, they’re trained by finding the probability distribution of next words. If the probability distribution matches that of the text in question, they mark it as “AI generated”. But this is an extremely flawed process. Consider the string “We hold these truths to be self _______”. Almost everyone knows the next word is “evident”. The probability distribution is basically 100% on that word. Does that mean if I quote the Declaration of Independence in a paper I was cheating? Of course not. But these AI detectors aren’t smart enough to know that. And there are plenty of teachers and professors who aren’t smart enough to understand the limitations of the tool.
