Sony Music Entertainment and Warner Music Group have filed a new copyright lawsuit against Anthropic, claiming the artificial intelligence giant “illegally harvested” more than 20,000 of their songs to train its models.
The case, which follows a similar lawsuit by Universal Music Group, BMG and Round Hill, claims Anthropic stole thousands of songs to “fuel Claude,” including “Ain’t No Mountain High Enough,” Mariah Carey‘s “All I Want for Christmas is You,” and Taylor Swift’s “Paper Rings.”
