MiniMax H3 generates coherent 30-second music from text prompts

A r/StableDiffusion demo shows MiniMax H3 producing up to 30 seconds of coherent audio with custom lyrics, composition structure, instruments, and genres. Prompts use a MEDIA/SCENE/TIMELINE structure; the example generates a 1990s upbeat hip-hop rap track at 32x32 resolution, 20 steps.
