About
MiniMax Music 3 MiniMax Music 3 is a high-performance music generation model for creating complete songs up to five minutes long. Conditioned on lyrics and a detailed music description, it generates structurally coherent songs with expressive vocals, evolving arrangements, and stable long-form audio quality. MiniMax Music 3 combines an 8B Global LLM for long-range musical structure, a 0.6B Local LLM for frame-level acoustic detail, and a continuous hidden-state synthesis system based on Flow Matching and Flow-VAE. The model produces 32 kHz, 16-bit stereo WAV audio. Demo Explore music generation examples on the MiniMax Music 3 Demo. Complete Songs with Long-Range Coherence MiniMax Music 3 natively supports full-song generation up to five minutes. The model maintains musical themes, rhythm, vocal identity, and arrangement progression across long sequences, enabling complete structures such as intro, verse, pre-chorus, chorus, bridge, instrumental break, and outro. Fine-Grained Music Control The model accepts two complementary inputs: - Lyrics define the words to be sung and may include explicit section tags such as [Intro], [Verse], [Pre-Chorus], [Chorus], [Post-Chorus], [Bridge], [Instrumental], [Solo], and [Outro]. - Music description defines the musical style, emotional progression, vocal performance, instrumentation, arrangement, and production profile. For precise control, we recommend using a Structured Caption with three sections: - Global Metadata: genre, subgenre, BPM, key, scale, emotional progression, listening scenario, and production profile. - Vocal Details: vocal gender, timbre, performance style, harmony, backing vocals, and vocal effects. - Arrangement: primary and secondary instruments, section-level instrument evolution, groove, bass, percussion, textures, and spatial effects. This representation allows the model to follow not only a global style, but also the musical development of the song over time. Hybrid-LM MiniMax Music 3 uses a hierarchical autoregressive architecture that separates global musical modeling from local acoustic modeling. - The Global LLM (8B) predicts the first RVQ codebook frame by frame and models the song's long-range se

Using it via the API
Once AxForge deploys minimaxai-minimax-music3 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (minimaxai-minimax-music3 below is illustrative; you get the exact model name on deployment.)

Licence
The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
