What is Lyria 3.5?
Lyria 3.5 is Google DeepMind's current music model and the successor to Lyria 3, which Google now lists as legacy. It turns a text prompt, your own lyrics or images into a full song with vocals or an instrumental, and returns the lyrics with the audio. You can set genre, tempo, vocal style and length, or map sections to timestamps.
It runs in the Gemini app, Google Flow Music, Google Vids, Google AI Studio and the Gemini API. Flow Music lets you edit, remix and download stems; on the API each song is a single request with no follow-up edits. It is a closed model with no downloadable weights.

Lyria 3.5 pros and cons
Lyria 3.5 sounds clean and costs little, but strict filters, a mainstream-leaning sound and single-request API calls hold it back.
Pros
- Early users say its vocals and acoustic tracks sound real enough to pass for a recording, building on the clean vocals testers praised in Lyria 3.
- Free for anyone 18 or older in the Gemini app, and Flow Music's free plan includes WAV and stem downloads.
- Costs $0.08 per full song on the API, the same as the Lyria 3 Pro preview it replaces, with lyrics and structure returned alongside the audio.
Cons
- Safety filters block prompts that ask for a specific artist's voice or copyrighted lyrics, and users of the earlier Lyria 3 said harmless lyrics were rejected or rewritten too.
- It leans toward acoustic and mainstream pop: users say EDM, rock and harder styles sound tame, and some find Suno gets a catchy song with less effort.
- On the API each song is one request with no follow-up edits or Batch discount, and the same prompt can give a different song each time.
