The TurkuNLP team does have the best previous-generation language model for Finnish (FinBERT). The current version of ChatGPT speaks passable Finnish, although definitely not at the level it speaks English. None of the open-source models I've tried come close to ChatGPT performance. If they can gather a good multilingual dataset including the smaller European languages, and burn enough money on the compute, they could create a useful model for some specifically European use cases.
