New TTS/Chirp3/live audio model

Hello,
when can we expect some updates regarding 2.5-flash-native-audio or chirp3 model? We’re trying to use 2.5-flash-native-audio in our app but response takes too long compare to chirp3 (which is great, but voice is not that good as 2.5). Also 2.5 has it’s own problems with cutting off responses.
It would be good to have some information about potential updates as we want to use google models in our app.

Sincerely, Damian
