FlowMusic API v1
June 3, 2026
This is the experimental API for Google Flow Music by Google Labs, powered by the Lyria 3 Pro music model. Flow Music was formerly Producer AI, and originally Riffusion.
Flow Music turns a text prompt, mood, or lyric idea into a complete, fully-produced song — vocals, melody, and arrangement — using Lyria 3 Pro. It also covers (restyles) existing songs, adjusts lyrics in place, extends or replaces sections, and applies audio effects. Each generation returns up to two clips (an A/B pair).

Each generation costs ~5 credits and returns up to two clips (an A/B pair). All plans include daily top-up credits, so even Free generates a little each day. Max concurrent is how many generations the API runs at once per account (the maxJobs cap); monthly credits don’t roll over.
