No they didn’t. The study is misleading in a number of ways.
That explanation of the prime number thing doesn’t seem to actually match what’s in the paper. GPT4 goes from a wordy explanation of how it arrived at the correct answer, “yes”, to a single-word incorrect “no”. GPT3.5 goes from a wordy explanation that has the right chain of thought but the wrong answer “no” to a very wordy explanation with the correct answer “yes”. Neither of those seem to be predicated on either of the models just answering one way for everything.
@rastilin is making some unproven assumptions here. But it is true that the “math question” dataset consists only of prime numbers, so if the first version thought every number was prime and the second thought no numbers were prime, we would see this exact behavior. Source:
From Zhang et al. (2023), the paper they took the dataset from.
Surely it can’t just be a case of the LM saying a hard yes or no to any question of “is this prime” with the data they have, though? The results are a significant majority one way or the other in each case, but never 100%. Of the 500 each time, GPT3.5 has 37 answers go against the majority in March and 66 in July. That doesn’t seem like a hard one answer to any primality query to me, though that does come with the caveat that I’m by no means actually well studied on the topic
True, GPT does not return a “yes” or “no” 100% of the time in either case, but that’s not the point. The point is that it’s impossible to say if GPT has actually gotten better or worse at predicting prime numbers with their test set. Since the test set is composed of only prime numbers, we do not know if GPT is more likely to call a number “prime” when it actually is a prime number than when it isn’t. All we know is that it was very likely to answer “yes” to the question “is this number prime?” in March, and very likely to answer “no” in July. We do not know if the number makes a difference.
Ahh, I see what you’re getting at. Thanks for clarifying
Holy shit you weren’t kidding. The Markdown backticks being “not directly executable” is perhaps the dumbest take I’ve ever heard on ChatGPT, and that’s saying a lot. Wow
Damn, you’re right. The study has not been peer reviewed yet according to the article, and in my opinion, it really shows. For anyone who doesn’t want to actually read the study:
They took the set of questions from a different study (which is fine). The original study had a set of 500 randomly chosen prime numbers and asked ChatGPT if they were prime, and to support its reasoning. They did this to see if in the cases where ChatGPT got the question wrong, ChatGPT would try to support its wrong answer with more faulty reasoning - a dataset with only prime numbers is perfectly fine for this initial question.
The study in the article appears to be trying to answer two questions - is there significant drift in the answers ChatGPT gives, and is ChatGPT getting better or worse at answering questions. The dataset is perfectly fine for answering the first question, but completely inadequate for answering the second, since an AI that simply thinks all numbers are prime would be judged as having perfect accuracy! Some good peer review would never let that kind of thing slide.
