Google is making Lyria 3, its music generation model, available to developers in public preview through the Gemini API and Google AI Studio.
The model is designed to produce high-fidelity compositions with structural coherence across a full track, including vocals, verses and choruses, rather than the short, texturally thin clips that have characterised earlier music generation tools.
Two variants, two use cases
Developers can access Lyria 3 in two forms. Lyria 3 Pro is built for studio-grade, full-length songs of up to around three minutes. Lyria 3 Clip generates 30-second cuts for prototyping and social assets, with faster turnaround.
Both variants support realistic vocals, multiple languages and a range of genres. Both also expose controls for tempo conditioning, time-aligned lyrics and image-to-music input, allowing developers to shape mood and structure from a visual reference rather than text alone.
The watermark question
The detail that will draw the most attention is not the model's capabilities. It is the watermarking. Every track generated by Lyria 3 includes a SynthID digital watermark, which Google says can identify and verify AI-produced audio even after the track has been modified.
That is a meaningful commitment at a moment when AI-generated music is becoming hard to distinguish from human-made recordings. SynthID does not prevent misuse, but it creates a forensic trail. Whether that trail holds up in practice, and whether platforms will check for it, remains to be seen.
Building in Google AI Studio
The Google AI Studio workspace offers two creation modes. Text mode accepts natural-language prompts with parameters including tempo and key. Composer mode allows developers to assemble song sections with timing and intensity controls, giving more granular command over structure.
