  • MAGNeTCommunity

    MAGNeT is Meta's masked, non-autoregressive audio generator. Instead of predicting tokens left to right it fills masked audio tokens in parallel over a few decoding steps, so generation is faster than autoregressive MusicGen at similar quality. This Replicate packaging exposes the text-to-music and text-to-sound variants.
