Universal Music Group and Sony Music have filed a new lawsuit against the artificial intelligence company Suno. The legal action alleges that Suno used 61,000 copyrighted songs to train its recently released v6 AI model.
Why it matters
The plaintiffs claim that Suno engaged in wholesale theft and is attempting to launder data by training new models on previous unauthorized outputs. They further argue that Suno's recent partnerships confirm a viable market for training data, which undermines the company's fair use defense.
The lawsuit incorporates 61,000 new songs into the ongoing legal dispute. This filing follows the release of Suno's v6 model on September 11, 2026.
