How to Use the MiniMax Music 3 API

MiniMax Music 3 is available on EmpirioLabs. MiniMax Music 3 writes complete stereo songs from a style prompt and lyrics, up to five minutes long. It is billed per generated second with a ten second minimum, and it uses the same OpenAI-compatible audio generation endpoint as every other music model on the platform.

What it is

MiniMax Music 3 is MiniMax's open-weight music model. You describe the arrangement, optionally pass lyrics with section tags such as [verse] and [chorus], and get a finished song back as WAV, FLAC, or MP3. Instrumental is on by default. Turn it off and pass lyrics when you want a vocal track.

Generate a song

curl https://api.empiriolabs.ai/v1/audio/generations \
  -H "Authorization: Bearer $EMPIRIOLABS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "minimax-music-3",
    "prompt": "Warm analog soul ballad, intimate female vocal, piano and upright bass",
    "lyrics": "[Verse]\nCity lights fade into rain\n[Chorus]\nStay with the quiet refrain",
    "instrumental": false,
    "audio_duration": 10,
    "format": "mp3"
  }'

The same call from Python:

import requests

response = requests.post(
    "https://api.empiriolabs.ai/v1/audio/generations",
    headers={"Authorization": "Bearer YOUR_EMPIRIOLABS_API_KEY"},
    json={
        "model": "minimax-music-3",
        "prompt": "Warm analog soul ballad, intimate female vocal, piano and upright bass",
        "lyrics": "[Verse]\nCity lights fade into rain\n[Chorus]\nStay with the quiet refrain",
        "instrumental": False,
        "audio_duration": 10,
        "format": "mp3",
    },
)
print(response.json())

Controls worth knowing

• Prompt is the style brief: genre, vocal character, instrumentation, and mood.
• Lyrics only apply when instrumental is false. Put a structure tag on its own line before each section. The lyrics parameter lists the full set.
• Duration is 10 to 300 seconds. Songs are billed per generated second, with a 10 second floor.
• Format is WAV by default. FLAC and MP3 are also valid.

Calling notes

• Instrumental is on by default. Sending lyrics without instrumental: false still returns an instrumental. The samples above set it to false so the vocal request actually sings.
• Steps and guidance are pinned at 30 and 1.7. Those knobs are not on the public card.
• The public id is minimax-music-3. minimax-music3 still routes.
