It depends on the question. I try to avoid using them, but I’ve seen threads where the poster challenged the AI then the AI changed its answer.
I’m guessing if the question had been asked the other way and the answer were challenged, the AI would have changed its mind the other way.
I have read exchanges in which the AI confidently gives a wrong answer to a question with a numerical answer, and then when it is told the answer is wrong, it apologizes and then confidently gives a different wrong answer.
It’s quite ironic, because before AI, the one thing computers were really, really good at, is math.
