If you searched for "Suno vs Riffusion" and landed here: Riffusion doesn't exist under that name anymore. The 2022 open-source project became ProducerAI in 2025, Google bought it in February 2026, and it's now Google Flow Music, a Google Labs product at flowmusic.app running on DeepMind's Lyria 3 Pro. producer.ai's pricing page redirects there.
How Flow Music works
The big difference from Suno is the interface. Flow Music is a conversation: you describe what you want, it writes or takes your lyrics, generates, and you keep talking to change it. Since the July 2026 Spaces update it does covers, section replacement, extension and stem splitting, and because it sits on Google's stack, it can make the cover art and a video in the same workspace.
Suno is a form: Styles, lyrics with section headers, Exclude, sliders. That's more fields to fill, and more control over exactly what goes in.
Neither is better in the abstract. Chat suits people who think in descriptions and want to iterate quickly. A form suits people who already know the tempo, the drum pattern and where the bridge goes.
Price
Flow Music is cheaper at the low end: Starter is $6 a month for 3,000 credits, which Google estimates at about 600 songs. Plus is $18 and Member $48. There's also a free tier with daily top-up credits. Suno Pro is $8 a month billed yearly (about $10 month to month) for 2,500 credits and 20 downloads.
Rights and training data: the open questions
This is where Suno is easier to plan around today. Suno publishes its terms: commercial use on paid plans for songs downloaded within the allowance, remixes excluded. Flow Music's pricing page doesn't state download or commercial terms, so read Google's terms for your account before you release anything.
On training data, Google says Lyria 3 Pro uses material Google and YouTube have a right to use under their terms and partner agreements. A group of independent musicians sued in March 2026, saying their YouTube recordings were used without permission. Every Flow Music output carries a SynthID watermark. Suno says v6 was trained on licensed material from Warner, BMG and Believe, and is still being sued by Universal and Sony. Neither company's position is settled law.
Where Lyria 3 in Gemini fits
"Create music" in the Gemini app (beta since February 2026, US first) uses Lyria 3 to make 30-second tracks from text or a photo, with generated lyrics and cover art. Good for a Short, a jingle or a sketch. Not a song tool, and not a Suno competitor. Google's full-song product is Flow Music.
Moving prompts between them
Suno prompts translate well into a Flow Music chat, because the information is the same: genre and tempo, the vocal, the drums and bass, the section plan, the ending. Paste your Styles as the description and your lyrics with their headers. Going the other way, turn the chat's description into a Styles field in Suno's order (genre, tempo, feel first) and move every "no …" into Exclude. Our v6 prompt guide covers that order, and the free Styles checker catches the habits that break it.
The bottom line
If you like working by conversation, live in Google's tools, or want the lowest entry price, Flow Music is worth a serious try. If you're releasing songs and need the rights spelled out, or you rely on custom models trained on your own tracks, Suno is the more predictable choice today.
