Sony accuses Anthropic of 'brazen campaign' to train Claude on its music — and wants up to $150,000 a song
Sony Music and Warner Chappell sued Anthropic, alleging it illegally used copyrighted songs, including works by Taylor Swift and Mariah Carey, to train its AI model Claude. The companies seek up to $150,000 per song in damages, claiming Anthropic pirated works from digital archives. A judge previously ruled Anthropic downloaded 7 million pirated books for training.
