Universal Music Group and Sony Music have filed a second copyright-infringement complaint against Suno, focusing on the artificial intelligence music company’s v6 models.
Suno‘s v6 models were trained on a dataset that included licensed music from Warner Music Group and BMG, along with user data. The new filing cites 60,202 sound recordings that the labels believe Suno copied during its earlier training process. The complaint adds that those recordings “remain only a small portion of Plaintiff’s works that Suno infringed.”
Focus on v6 training data#
The two major music companies are also directing their claims at Suno’s latest models. The filing states:
“Suno has admitted that it trained v6 using ‘user interactions’ with previous iterations of its models. But these ‘interactions’ are the outputs of, and preference data derived from, Suno’s prior models.”
The complaint argues that v6 was trained on “synthetic outputs” of “prior tainted models.” That leads to the claim that “Suno trained v6 with material that exists only because Suno copied Plaintiffs’ recordings without authorization.”
Legal argument over v6#
The filing’s central line is: “v6 is not a fresh start; it is the fruit of the same poisoned tree.” It continues: “Suno’s development of v6 continued, rather than ended, its unauthorized exploitation of Plaintiffs’ Copyrighted Recordings.”
In a recent interview, Suno’s chief product officer Jack Brody said, “I think of this moment as really marking a new chapter for Suno.” In the legal filing, UMG and Sony Music contend that v6 is another chapter in the same copyright-infringement playbook that prompted their original lawsuit.
