"""Constants of the PersonaPlex full-duplex integration.

|
|
PersonaPlex (``nvidia/personaplex-7b-v1``) is a Moshi finetune: a pure-lockstep
|
|
full-duplex speech-to-speech model running at the Mimi codec frame rate
|
|
(12.5 Hz / 80 ms). The values are fixed by the pretrained checkpoint; they
|
|
live here so the rest of the package never hard-codes them.
