I've never had ChatGPT just say "actually I don't know the answer" it just gives me confidently correct wrong information instead.
GPT-4 will. For example, I asked it the following:
It responded:
Now, obviously, this is a made-up term, but GPT-4 didn't confidently give an incorrect answer. Other LLMs will. For example, Bard says,
Interestingly, the answer from bard sounds like it could be true. I don't know shit about fluid dynamics but it seems pretty plausible.
Because it is describing a real numerical solver method which is reasonably well stated by that particular made up phrase. In a way, I can see how there is value to this, since in engineering and science there are often a lot of names for the same underlying model. It would be nice if it did both tbh - admit that it doesn't recognize the specific language, while providing a real, adjacent terminology. Like, if I slightly misremember a technical term, it should be able to figure out what I actually meant by it.
Yeah sounds like something that needs to be tested, could be total bullshit
That is, I guess, because it doesn’t actually know anything, even things it’s accurate about, so it has no way to determine if it knows the answer or not.
I fucking love when my students bring "chat" in as their tutor and show me the logic they followed... Bro, ChatGPT knows the correct answer, but you asked a bad question and it gave you its best guess hidden as a factual statement.
To be fair, I spend a lot of time teaching my students how to use LLMs to get the best results while avoiding "leading the witness."
It doesn't "know" the correct answer. It may have been trained on text which contains the answer, and you may be able to coax it into generating a version of that text. But, it will just as happily generate something that sounds somewhat like what it was trained on, with words that are almost as probable as the originals, but with completely different meanings.
The only times I've seen this is when it says their information is from like 2019 so they don't know. But this is very fringe things.
Which is how most politicians get elected.
I’ve had it tell me that it cant find anything about a question. But it’s usually when I ask for sources, frame the question as ‘is there anything online’, or otherwise ask it to do some research. If I just ask it a naked question it’ll always give an answer.
It's a gun store employee.
Well that's a surprise. Never used one so far as I know so I wouldn't know much but from what I've seen, having done my research, it's kinda helpful but not exactly the best tool for every job, I still prefer just manually going through things but hey I wouldn't know much since perhaps I just haven't come across using it in my line of work yet
