Sony Music Publishing and Warner Chappell Music have sued Anthropic, alleging thousands of copyright infringements from illegally downloading protected compositions to train its Claude models. The publishers seek a jury trial, up to $150,000 per infringed work, and $25,000 per instance of removed copyright management information. The complaint follows earlier suits by Concord Music Group and Universal Music Group, and a $1.5 billion settlement with authors.
