■ AI-SUMMARIZED FROM 1 SOURCE ▸ TIMELINE

Sony and Universal Music Group filed a new lawsuit against Suno, claiming its v6 AI model still violates copyright by training on outputs from previous versions that used unlicensed music from YouTube and other sources.

The labels argue that Suno's latest model perpetuates copyright infringement through its training methodology, even as the company develops new versions of its music-generating AI. Sony and UMG are among the music industry's most prominent players and have notably refused to sign licensing agreements with Suno, distinguishing them from other major labels that have made deals with AI music companies. The lawsuit represents the latest escalation in ongoing disputes between AI music startups and the recording industry. Labels have raised concerns about AI systems trained on copyrighted music without permission, while companies like Suno argue their tools represent transformative technology. Suno has faced multiple legal challenges since its launch, with rights holders claiming the company used their catalogs to train its models without consent or compensation. The company has previously defended its practices as lawful.
