MiniMax Releases Open-Weights MiniMax-Music3: Full Five-Minute Songs From Lyrics and Captions

MiniMax has released MiniMax-Music3 as an open-weights music generation model capable of producing complete five-minute songs from a combination of lyrics and a structured descriptive caption. Unlike shorter-clip music models, the five-minute output length makes it practically usable for full track generation rather than just demo snippets. The open-weights release means developers can fine-tune, self-host, and integrate the model without API dependency or usage caps. For teams building creative tools, game audio pipelines, or content production platforms, this is a significant capability upgrade in the open-source music AI landscape. Developers should benchmark its output quality against proprietary alternatives like Suno and Udio to assess where it fits production workflows.
