Researchers found that ChatGPT's performance varied significantly over time, showing "wild fluctuations" in its ability to solve math problems, answer questions, generate code, and do visual reasoning between March and June 2022. In particular, ChatGPT's accuracy in solving math problems dropped drastically from over 97% in March to just 2.4% in June for one test. ChatGPT also stopped explaining its reasoning for answers and responses over time, making it less transparent. While ChatGPT became "safer" by avoiding engaging with sensitive questions, researchers note that providing less rationale limits understanding of how the AI works. The study highlights the need to continuously monitor large language models to catch performance drifts over time.

My understanding is this claim is basically entirely false. The tests done by these researchers had some glaring errors that when corrected, show gpt-4 is getting slightly better at math, if anything. See this video that describes some of the issues: https://youtu.be/YSokS2ivf7U

TL;DR The researchers gave new GPT questions from two different pools. It's no surprise they got worse answers.

You shouldn't need to be a prompt engineer just to get answers to math questions that are not blatantly wrong. I believe the prompts are included in the paper so that you don't have to guess if they were badly formatted.

The problem is they aren't comparing apples to apples. They asked each version of GPT a different pool of questions. (Edited my post to make this clear).

Once you ask them the same questions, it becomes clear that ChatGPT isn't getting worse at math, because it has been terrible all along.

I see. Thanks for clarifying
