For Lyria 3.5 via the Gemini API, the docs say all generated audio carries a SynthID watermark and that prompts requesting specific artist voices or copyrighted lyrics are blocked. The Gemini API Additional Terms (effective March 23, 2026) say Google won't claim ownership of generated content and may generate similar content for others. The pages read give no training-data statement for Lyria and no music-specific commercial-use tiers; the DeepMind page lists artist partnerships but no licensing detail.
