MiniMax Music 3 - GGUF Quantizations

This repository contains GGUF quantizations for MiniMax Music 3 (Hugging Face model), a music generation model capable of synthesizing complete, structurally coherent songs up to 5 minutes long at 32 kHz stereo.

For full architectural details, model specifications, and benchmarks, please refer to the official MiniMax-Music3 GitHub repository.

Prompting Guide

MiniMax Music 3 accepts two primary conditioning inputs: Lyrics and a Music Description.

1. Lyrics & Section Tags

Structure your lyrics using standard uppercase section tags placed on their own lines:

[Intro]
(Soft acoustic guitar melody)

[Verse 1]
Morning light filtering through the pine
Every quiet street is yours and mine

[Pre-Chorus]
The horizon starts to glow

[Chorus]
Softly the world begins to breathe
Waking up under golden leaves

[Bridge]
Time moves slow in the morning haze

[Chorus]
Softly the world begins to breathe
Waking up under golden leaves

[Outro]
Fading into the dawn

Supported section tags include: [Intro], [Verse], [Pre-Chorus], [Chorus], [Post-Chorus], [Bridge], [Instrumental], [Solo], and [Outro].

2. Structured Caption (Music Description)

For precise control over the arrangement and performance, structure your music description across three areas:

• Global Metadata: Genre, subgenre, tempo (BPM), key, scale, emotional progression, listening scenario, and production style.
• Vocal Details: Vocal gender, timbre, performance delivery, harmony, backing vocals, and vocal effects (e.g. reverb, delay).
• Arrangement: Primary and secondary instruments, section-by-section instrument progression, groove/rhythm, bassline, percussion style, and spatial atmosphere.

Example Structured Caption:

Genre: Indie Folk Pop. BPM: 98. Key: G major. 
Mood: Warm, intimate, and uplifting with a gradual dynamic build.
Vocals: Close, breathy female lead vocals with light double-tracking and airy reverb; two-part harmonies enter during the chorus.
Arrangement: Fingerpicked acoustic guitar and soft felt piano throughout. Subdued kick and upright bass join in the second verse. Full folk percussion, tambourine, and subtle ambient strings enter during the chorus.

Limitations

• Generation is non-streaming.
• The tokenized text prompt is limited to 5,000 tokens.
• Audio generation is capped at 9,000 acoustic frames (~5 minutes).
• Section tags and descriptions provide generative conditioning; tempo, key, and lyrical timing may vary slightly.
