Description: Block unveiled Dessa, a full-duplex speech-to-speech model trained from scratch only on human conversation audio (no text, no pretrained models). It listens and talks at once, hears and speaks emotion, was trained on one NVIDIA GB200 NVL72 and runs faster than real time on a MacBook Pro M4 Max or better; Block is giving AI safety researchers early access.
