Google launches Lyria 3.5 music model in Flow Music; Gemini API GA follows
Google DeepMind released Lyria 3.5, its third Lyria model in about five months, first in Google Flow Music, with better melodies, lyrics, more natural vocals and tempo/duration control; it became generally available in the Gemini API as lyria-3.5 on 2026-09-03 at $0.08 per full song.
Key facts
- Launched 2026-07-29 in Google Flow Music (the former ProducerAI)
- Improvements: musicality, lyric quality and prompt adherence, vocal expressiveness and pronunciation, tempo and duration control
- Gemini API id lyria-3.5 (Stable, Interactions API), GA 2026-09-03; $0.08 per song, no free tier
- 44.1 kHz stereo MP3/WAV, text + image input, SynthID watermark
- Lyria 3 Clip/Pro previews now labelled legacy on the Gemini API pricing page
What happened
Lyria 3.5 replaced Lyria 3 Pro behind Google Flow Music's song generation on launch day, at no extra cost to Flow Music users. About five weeks later it reached general availability for developers in the Gemini API's Interactions API. As of 2026-09-29 it was not yet listed on Vertex AI (Gemini Enterprise Agent Platform), which still offers Lyria 3 previews and Lyria 2.
Why it matters
Google now ships a GA, watermarked, pay-per-song music model to developers, something Suno (web app only, API only "being explored") and Udio (no public API) do not offer.
