    "summary": "No software fee for local use within license terms; GPU compute is your cost.",

  "limitations": [
    "MusicGen does not generate realistic vocals",
    "English prompts are best supported; styles and cultures are represented unevenly",
    "Outputs can collapse to silence, and prompt experimentation may be necessary",
