Riffusion vs Stable Audio
Riffusion scores 38 to Stable Audio's 16 on public evidence for AI music generation, and they rank #2 and #4 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Riffusion
Text-to-music model with a generous free tier and a vocal-aware editor.
+ Free generation with no hard monthly cap, and the original model was published openly.
− Full-song quality trails Suno; the open repo is a hobby release, not the product.
Stable Audio
Stability AI's text-to-audio generator for music and sound effects, with an open-weights variant.
+ Good at sound effects and samples as well as music, and trained on licensed audio for lower legal risk.
− Tracks top out at a few minutes and vocals are weak compared with Suno or Udio.
