Is it a dumb-down version of GPT like the current voice model? At least in french, I find the current GPT voice mode to be useless, to the point I only use the dication mode. I would ask a question and it would answer something along "That's a interesting question. I can help you with that. Anything you want to know about X?" I would ask again and it would answer the same kind of non answer.
