I don't speak Te Reo (yet) so I can't test it out but goddamn I'm impressed that the model supports over 1100 languages, and it's awesome that it's open source!
I'd be interested to see how well it handles different dialects of Te Reo - the Kai Tahu dialect we have round here has some significant pronunciation/spelling differences and a few different words when compared to "standard" Māori.
