Lyria 3 Commercial Use: What's Allowed in 2026

Google's Lyria 3 is the music-generation engine behind the Gemini app's "create music" feature and a public-preview model on Vertex AI. The first question every paid creator asks is the same: can you use Lyria 3 commercial use cases — client work, monetized YouTube, paid product soundtracks — without legal headaches?

The short answer is yes, with conditions. Google's terms grant you a broad commercial license to outputs you generate through your subscription or paid API access, but every track ships with a SynthID watermark, the model is designed not to mimic specific artists, and the rules differ slightly between Gemini consumer plans, the Gemini API, and Vertex AI. Below is the working picture, current as of May 2026.

What Lyria 3 actually is

Lyria 3 is Google DeepMind's family of music-generation models. It comes in two SKUs:

• Lyria 3 — generates audio clips up to 30 seconds. Optimized for speed and short-form use (social loops, sound stings, prototyping). Released February 2026.
• Lyria 3 Pro — generates structured tracks up to 184 seconds (~3 minutes), with prompt-level control over intros, verses, choruses, and bridges. Supports vocals, lyrics, and reference-image-to-music composition. Released March 25, 2026.

Both models accept text prompts, image-to-music conditioning, and instrumental-only output. Google trained the Lyria 3 family on YouTube and partner data the company says it has the right to use, and built filters that check generated output against existing recordings before delivery.

Can you use Lyria 3 for commercial purposes?

Yes — across all three official surfaces — but the rights, scale, and pricing differ. Here is the breakdown.

Gemini app (consumer subscriptions)

Lyria 3 in the Gemini app sits behind paid plans:

Under Google's standard Gemini Apps Additional Terms, you retain ownership of content you generate, including Lyria 3 output, and Google is granted a license to use it for service operation and improvement. That ownership clause is what makes commercial use legally workable: a vlog soundtrack, a Twitch-stream bumper, or a podcast intro generated under a paid Gemini plan is yours to monetize, subject to the prohibited-use policy below.

Vertex AI (enterprise)

For business and product work at scale — embedding Lyria 3 in a SaaS app, generating soundtracks for a game catalogue, on-demand music for a marketing platform — Google directs you to Vertex AI, where Lyria 3 and Lyria 3 Pro sit in public preview. Vertex AI is governed by the Google Cloud Service Specific Terms; outputs are owned by you (the customer) and licensed for commercial use that complies with the Generative AI Prohibited Use Policy. Pricing is enterprise-negotiated. The preceding Lyria 2 model was billed at $0.06 per 30 seconds, which is a useful order-of-magnitude reference until Google publishes Lyria 3 list pricing.

Gemini API and AI Studio

The same Lyria 3 Pro endpoint is reachable as a developer API through both Google AI Studio and Vertex AI's Gemini API. The endpoint name in current documentation is lyria-3-pro-preview. AI Studio offers a free tier for testing; production use requires a paid API key. Token-based billing applies. You can build commercial products on top of either — what changes is the contractual layer (Cloud Service Specific Terms vs Google APIs Terms) and the level of enterprise support.

What Google's terms actually say

Three documents govern Lyria 3 commercial use:

1. Google Generative AI Additional Terms — covers ownership and license. You own your outputs; you grant Google the right to use them to operate and improve the service.
2. Generative AI Prohibited Use Policy — bans certain content categories for any output, regardless of commercial vs personal intent. The list includes IP violation, deceptive impersonation, sexually explicit content, and illegal-activity facilitation. Notably, commercial use itself is not on the prohibited list.
3. Service-specific terms — Vertex AI work falls under the Cloud Service Specific Terms; Gemini app work falls under the Gemini Apps Additional Terms. Both grant you commercial usage rights to outputs you create.

The point that surprises some users: Lyria 3 is designed not to imitate specific artists. If you prompt with "in the style of [famous artist]," Google says Gemini will treat the artist name as broad creative inspiration rather than a clone target, and post-generation filters compare output against existing recordings. This is by design — it lowers the legal-risk surface for everyone shipping the model.

SynthID and C2PA — what watermarking means for distribution

Every Lyria 3 and Lyria 3 Pro output carries:

• SynthID — Google's imperceptible audio watermark, designed to survive common transformations (re-encoding, format change, noise overlay) and to be detectable by Google's verification tools.
• C2PA — content provenance metadata declaring the file as AI-generated.

For most commercial use cases (background music in videos, soundtracks in apps, podcast intros), the watermark has no audible impact and does not affect monetization. It exists so that platforms, fact-checkers, and rights organizations can identify AI-generated audio if they need to. It is not DRM. You can still distribute, sell, license, and monetize the track. The practical concern is platforms with explicit AI-content disclosure rules — for instance, YouTube requires creators to disclose synthetic media in monetized content, and the SynthID and C2PA metadata help you stay compliant by default.

Practical checklist before using a Lyria 3 track commercially

Before a Lyria 3 output ships in a paid project, run through:

1. Generate on a paid plan. Free-tier output (where available) usually carries non-commercial restrictions. Subscription, API, and Vertex AI access do not.
2. No artist names or brand mimicry in the prompt. Even though filters exist, removing the prompt removes the risk class entirely.
3. No vocal cloning or voice impersonation. Lyria 3 vocals are synthetic; do not direct them at named real people.
4. Disclose AI generation where the platform requires it. YouTube, TikTok, and Instagram Reels all have synthetic-media disclosure rules that map cleanly to the C2PA flag.
5. Keep the source prompt and generation timestamp. Useful evidence if a copyright dispute ever surfaces.
6. Stay current on policy changes. Google's Generative AI Prohibited Use Policy and the Gemini Apps Additional Terms are updated periodically; bookmark and re-check before major releases.

Lyria 3 vs Lyria 3 Pro for commercial work — which one you need

For the majority of commercial creative work, Lyria 3 Pro is the right tool. The base Lyria 3 model is mostly useful when the unit you actually need is short and you are producing many of them — that is where the cheaper per-clip economics matter.

FAQ

Can I use Lyria 3 in a commercial product?

Yes. If you generate the audio under a paid Gemini subscription, the Gemini API, or Vertex AI, Google grants you ownership of the output and a license that covers commercial use, subject to the Generative AI Prohibited Use Policy.

Can you use Lyria 3 for commercial work without attribution?

Google does not currently require attribution for Lyria 3 outputs used commercially. Some platforms (YouTube, TikTok) require AI-content disclosure on user uploads — that is a platform rule, not a Google licensing requirement. The SynthID watermark and C2PA metadata are embedded automatically.

Can Lyria 3 be used for commercial YouTube monetization?

Yes. A track generated under a paid Gemini plan can be used as background music in a monetized YouTube video. YouTube's synthetic-content disclosure policy applies — mark the upload as containing AI-generated content where prompted.

Can I use Lyria 3 Pro in a paid client project?

Yes. Lyria 3 Pro outputs from a paid subscription, Gemini API call, or Vertex AI request are owned by you and may be licensed or delivered to a client as part of paid creative work. Confirm contractually that the client understands the audio is AI-generated and watermarked.

Does the SynthID watermark show up in the audio?

No. SynthID is designed to be imperceptible to human listeners. It survives common audio transformations (compression, re-encoding, format change) but does not change how the track sounds. C2PA metadata is also embedded in the file but is not audible.

Do I own the music Lyria 3 generates?

Under Google's Generative AI Additional Terms, yes — you own outputs you generate. Google retains a license to use that content to operate and improve the service. Note that copyright protection over purely AI-generated audio varies by jurisdiction (the U.S. Copyright Office currently considers fully AI-generated work uncopyrightable without significant human authorship). Ownership and copyrightability are different questions.

Where to go next

If you are producing visual creative work alongside your AI music — covers, thumbnails, marketing imagery, character art — limeAI's AI image generator is built on the same commercial-use posture: paid access, owned outputs, no provider lock-in. Same workflow philosophy, applied to image generation.
