I know it sounds like a glib answer, but in reality the answer to both questions is you don't know for certain in either case. Honestly I would say both are incorrect for at least some portion of their responses, but you seem to be insinuating that humans are closer to 0% while the LLM's percent is higher. In my estimation the LLM is probably less often incorrect but that's just my opinion. I am sure a more rigorous study could be conducted though.
Also, the value of a tutor that in and encouraging way corrects my verb conjugation of być (to be) for the 500th time has a lot more value than the risk of it being wrong on a corner case.
A human tutor would semi-arrogantly have told be off and asked me to look at the dictionary (Yes, I have studied English, German, Spanish, and French in school, I have had more language teacher than anything else)
I'm not arguing in any way I'm legitimately curious, as someone who has dabbled in language learning, as well as trying to use ChatGPT as a tutor, how its track record has been. Hallucinations was definitely one of my concerns when asking it about language stuff.
But again, in english, when is it appropriate to use mom and mother? It really depends on the context, culture, and relations.
Also hallucinations are probably a good thing for language learning. especially when you have an interface, chat, where you can interrogate – and an AI that does not get offended when you question it.
We're not experts as a result, obviously, but it helped us get around and stuff which is fun. It was pretty much a crash course started as we were landing in Santiago (which is where we entered the country).
This should really be emphasised. Correctness might not be entirely on every time. But learning pace and engagement is so much higher, that it more than makes up for it.
Especially engagement is a point where ChatGPT wins over all human teachers.
Truth to be told, human WILL never match ChatGPT's patience and coverage when it comes to explain most insignificant details of one particular language, any time anywhere you wanted. It takes out the fear/embarrassment factor when it comes to a human tutor.
