Suno just swapped out the AI model powering its song generator - and the new one was built without the music that got the company sued in the first place.
Suno says its latest model, Suno v6, was trained without any of the music used to build earlier versions of the tool. The company is swapping in licensed material instead, replacing the previous model entirely rather than patching it. The change comes as Suno faces a growing pile of copyright lawsuits over how those earlier models were trained. Suno hasn't detailed which catalogs it licensed or how much of v6's training data those deals actually cover.
Retraining from scratch on licensed music is an expensive, disruptive move, not a quiet policy tweak - it signals Suno expects the lawsuits over its old models to stick around regardless of what v6 does differently. For an industry still waiting on courts to settle whether AI training on copyrighted music counts as fair use, that's a tell: the company that trained on it first is hedging rather than waiting for a ruling.
A cleaner model going forward doesn't make the copyright case against the old one disappear.
