I saw this on reddit, thinking it’s a joke, but it’s not. GPT 5 mini (and maybe sometimes 5) gives this answer. You can check it yourself, or see somebody else’s similar conversation here: https://chatgpt.com/share/689a4f6f-18a4-8013-bc2e-84d11c763a99
Wonder what else it’s wrong about, if it misses somehing this obvious. It seems to be ChatGPT is getting worse by every update
While AI reasoning models will continue to improve, the data sets they pull from will continually get worse.
That's not my understanding based on this article I read yesterday.

That's a blog post, not an article.
Why don't you give this one a read: https://arstechnica.com/ai/2025/08/researchers-find-llms-are-bad-at-logical-inference-good-at-fluent-nonsense/
Or, even better, why not read the actual study: https://arxiv.org/pdf/2508.01191
