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 up to ~3 mins long (5+ with extend) — 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).

Sign in to flowmusic.app with your Google account. See the Flow Music pricing page for plans and credit allowances.

A song costs about $0.008–$0.013 on paid plans (see the cost calculator below for details), vs $0.08 per song on Google’s official Lyria 3 Pro API. Roughly 6–10× cheaper, and includes cover, remix, extend/replace, effects, and stem-splitting. Downloads (mp3, wav, m4a, and stems) are free.

💲 Cost calculator

Each generation costs ~5 to 10 credits and returns one or two songs (5 credits per song). 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).
