For one month beginning on October 5, I ran an experiment: Every day, I asked ChatGPT 5 (more precisely, its “Extended Thinking” version) to find an error in “Today’s featured article”. In 28 of these 31 featured articles (90%), ChatGPT identified what I considered a valid error, often several. I have so far corrected 35 such errors.
It isn’t doing anything automatically; it isn’t moderating for me. It’s just flagging submissions for human review. “Hey, maybe have a look at this one”. So if it falsely flags something it shouldn’t, which is common, I simply ignore it. And as I said, that error rate is moderate, and although I haven’t checked the numbers of the error rate, it’s still successful enough to be quite useful.
