If people wanted that, they could just ask an LLM to be their language coach. The big issue is that with a foreign language, you cannot really verify that anything the model gives you is correct. And with how LLMs work, the wrong answers will look very convincing. I don't think that's a good idea.

This is begging the question a bit, but yep. We all have access to LLMs, so why do we need a middleman like DuoLingo taking the output of an LLM and cluttering it up with irrelevant ads?
