MiniMax releases open-weights AI model for full 5-minute songs

MiniMax released MiniMax-Music3, an open-weights text-to-music model. Given lyrics with section tags and a structured caption, it generates a complete song up to five minutes long in a single pass, output as 32kHz, 16-bit stereo WAV.

Why it matters: Most music-generation tools top out around one or two minutes, or stitch multiple passes together; a single-pass five-minute output with open weights lowers the bar for developers to build music tools without licensing a closed API like Suno or Udio. Open-weights releases have been rarer in music generation than in text or image models, so this adds real competitive pressure in that niche.
