MiniMax Music 2.5

MiniMax Music 2.5 is a high-fidelity music generation model developed by MiniMax, released in early 2026. It is designed to bridge the gap between AI-generated tracks and professional studio recordings by focusing on two primary technical advancements: Paragraph-level Precision Control and Physical-grade High Fidelity. The model functions as an end-to-end producer, handling composition, vocal performance, arrangement, and mixing in a single generation pass, producing audio at 48kHz hi-fi quality.

A central feature of the model is its support for 14 distinct structural tags, which allow users to define the emotional arc and arrangement of a song with surgical accuracy. These tags include [Intro], [Verse], [Chorus], [Bridge], [Hook], [Build Up], [Interlude], [Outro], [Pre Chorus], [Post Chorus], [Transition], [Break], [Inst], and [Solo]. By integrating these tags directly into the lyrics or prompt, creators can control transitions, climaxes, and instrumentation shifts, moving away from the "black-box" style of generation common in earlier models.

The model's vocal synthesis is optimized for realism, featuring smooth pitch transitions, natural breathing patterns, and resonance shifts that mimic human warmth and vibrato. It supports over 40 languages for singing and maintains a library of over 100 studio-grade instrument tones. The subsequent Music 2.5+ update further expanded the model's capabilities by unlocking dedicated instrumental-only generation, allowing for the creation of complex scores for film, gaming, and advertising without vocal tracks.

For optimal results, users are encouraged to use a combination of a descriptive style prompt and structured lyrics. The style prompt should specify the genre, mood, and specific instruments (e.g., "Soulful blues, electric guitar, rainy night"), while the lyrics use structural tags to define the song's layout. The model features a large context window of 50,000 tokens, accommodating long-form lyrics and detailed arrangement instructions.
