Commercial use — Permitted subject to conditions

No separate licence or output-ownership statement is published for Lyria RealTime; it is an experimental Gemini API model governed by the Gemini API terms and the Generative AI Prohibited Use Policy.

  • The terms restrict what you may generate. No separate licence or output-ownership statement is published for Lyria RealTime; it is an experimental Gemini API model governed by the Gemini API terms and the Generative AI Prohibited Use Policy
  • Output is watermarked. The documentation states plainly that 'output audio is always watermarked' and that prompts are safety-filtered, with rejected prompts surfaced in a filtered_prompt field

The conditions above were extracted from the licence notes recorded during research, and each one shows the sentence it came from so you can check the reading. Read the licence before you rely on any of this. Nothing on this page is legal advice, and this site does not tell you a model is cleared for commercial use.

Strengths

  • True real-time interactive steering (BPM 60-200, scale, density 0-1, brightness 0-1, guidance 0-6)
  • mute_bass, mute_drums and only_bass_and_drums toggles for live arrangement
  • 48 kHz stereo PCM stream
  • Smooth transitions between weighted prompts

Weaknesses

  • BPM and scale changes require a context reset
  • All output watermarked
  • No documented file-based deliverable or session length limit

Where the sources disagree

Recorded rather than resolved. Picking the tidier number would hide the fact that the vendor's own pages do not agree.

What to understand before using it

Explainers naming the mechanisms this model's own documentation mentions.

MCP servers that front Google

Servers in the media MCP directory whose own description or homepage names this vendor. Absence of a server here is not evidence that none exists: most publish no tool list at all.

Shotcraft hosts no sample output. Judging a model means watching its own showreel with your own eyes, and a clip re-hosted here would be a clip we chose.
