Music 2.0

This documentation is valid for the following list of our models:

• minimax/music-2.0

Try in Playground

A fast and cost-efficient music generator optimized for high-quality music production. The model creates full-length songs (up to 4 minutes) featuring natural-sounding vocals and detailed instrumental arrangements.

How to Make a Call

Create AI/ML API Key

Step-by-Step Instructions

Generating an audio using this model involves sequentially calling two endpoints:

• The first one is for creating and sending a video generation task to the server (returns a generation ID).

• The second one is for requesting the generated video from the server using the generation ID received from the first endpoint.

Below, you can find two corresponding API schemas and examples for both endpoint calls.

If you want to learn how to call AI models via API from the very basics, feel free to use our Quickstart guide.

API Schemas

Generate music sample

This endpoint generates a music piece based on the prompt (which includes style instructions) and the provided lyrics. It returns a generation task ID, its status, and related metadata.

post

Body

modelstring · enumRequiredPossible values:

promptstring · min: 10 · max: 2000Required

A description of the music, specifying style, mood, and scenario. Length: 10–2000 characters.

lyricsstring · min: 10 · max: 3000Required

Lyrics of the song. Use ( ) to separate lines. You may add structure tags like [Intro], [Verse], [Chorus], [Bridge], [Outro] to enhance the arrangement. Length: 10–3000 characters.

Example: [Verse] Streetlights flicker, the night breeze sighs Shadows stretch as I walk alone An old coat wraps my silent sorrow Wandering, longing, where should I go [Chorus] Pushing the wooden door, the aroma spreads In a familiar corner, a stranger gazes

Retrieve the generated music sample from the server

After sending a request for music generation, this task is added to the queue. This endpoint lets you check the status of a audio generation task using its id, obtained from the endpoint described above. If the video generation task status is complete, the response will include the final result — with the generated audio URL and additional metadata.
