An AI model you can play like an instrument

Magenta RealTime 2 is an open-weights live music model — driven by a MIDI keyboard, live text prompts, and even hand gestures — generating a continuous 48kHz stereo stream that runs locally on Apple Silicon MacBooks.

40ms

Frame size — down from 2000 ms in MRT1

<200ms

Average control latency, running locally

48kHz

Continuous stereo music output

A 50× smaller frame for instant response

Shorter frames mean the model reacts to your input almost as you play it.
