My new hobby is asking GPT-5 Thinking to find errors in every @Wikipedia page I read. Interestingly, almost every page I checked has at least one error. 🧵
Some of these errors can be quite serious.
Are these just hallucinations by GPT-5 Thinking? Nope. I checked the sources and as far as I can tell they are all real errors.
Even the Wikipedia page on Wikipedia has an error.
