This question is motivated by a question I read on another online forum, to which the answerers said that when they tested ChatGPT's Hindi, it made grammatical errors all the time and was also trash at word-choice. This is in stark contrast to my understanding of its performance in normal English, in which I don't normally find a mistake.
It made me think: maybe ChatGPT was trained on fewer Hindi texts.
The question that arose: has the connection been studied between how much text an AI bot is trained on for a certain language, and how accurately it can write original content in that language?
This would be analogous to observing second-language human learners and I imagine that it is a worthwhile thing to study.
(Context: I have no background in linguistics at all, but this is the best place to put my query.)
Thanks!
