Suno v3.5
Suno v3.5 is Suno AI's May 2024 release, building on v3 by extending song length to up to four minutes, improving song-structure coherence, and tightening prompt adherence. Suno is a text-to-music system: given a description or lyrics, it generates full multi-track songs with realistic vocals, accompaniment, and mixdown in most popular genres. v3.5 broadened genre coverage and added a lyric-editing workflow. Available through the Suno web app and mobile app on a credit-based subscription.
