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.

For me it’s like using a coffee machine as a stopwatch, and then complaining that it doesn’t always give the exact time lapsed.

If it's a coffee machine that's so advanced it was uninaginable a decade ago, you'd expect it not to perform worse over time.

My point was that a coffee machine is designed to make coffee, not to keep track of time. Maybe it always takes roughly the same amount of time to make a coffee, and so someone uses it as a proxy stopwatch. But it can very well suddenly take more or less time, without anything being wrong about it – maybe different coffee brands, cleaned pipes, or whatnot.

ChatGPT is an algorithm designed to parrot language, not to perform mathematical reasoning based on logic rules.

You are not wrong, but I think public perception is different. It doesn't help, that OpenAI is pushing their models as problem solvers:

GPT-4 can solve difficult problems with greater accuracy, thanks to its broader general knowledge and problem solving abilities. (https://openai.com/gpt-4)

I didn't know they made such claims. They're borderline dangerous claims...
