Music Giants Sue Suno Over AI Model V6, Claim Infringing Outputs

Sony Music Entertainment and Universal Music Group filed a new 45‑page lawsuit in the District of Massachusetts accusing Suno’s new v6 AI music models of infringing their copyrights by training on the outputs of prior, allegedly infringing models; the labels argue that training on those outputs does not erase infringement. Suno says v6 uses licensed content from partners (WMG, BMG, Believe) and user-generated signals, and that its training aligns with fair use, noting licensing deals with partners. The case cites 60,202 infringed recordings since Suno’s debut and seeks a ruling of infringement, statutory damages and attorneys’ fees, marking another front in the ongoing AI copyright battles in the music industry.
