Does anyone actually believe the premise of Neuro-sama that she is an AI? The original premise was that she is a lightweight AI model livecoded on streams, but that is obviously not the case anymore.
Let alone a decent sized model on a couple 4090s or similar, pretty gud t/s to churn out tts/stt/response/control model actions and emotes.
Even if it were a human, that would require both fast typing and a fast TTS.
