We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence.

@jack @murwin I ask again. We run it locally to do what? Other than chatting about this and that, what is the actual use case? is this envisioned to become a UI / harness for other models? A more intuitive engine used to direct other models? Please enlighten us, Jack.

@starascendinm@jack @murwinok Pro M4 Max or better. Your MacBook Air M5 with 24 GB RAM falls short—the Air’s base chip and thermals can’t match the Max’s GPU/CPU power for real-time full-duplex inference. Dessa isn’t public yet either (early access only for AI safety researchers).

@jack @murwin It isn't intelligence, programs are not intelligent, and you are as stupid as any other coder, or person impressed by coding. Playing the piano with even base level skill is worlds beyond the most complicated coding. And your results are shit, too.
Enjoy the adoration of morons.
