    Sony Music Publishing and Warner Chappell sued Anthropic in California, naming executives Dario Amodei and Benjamin Mann and demanding up to $150,000 per allegedly copied lyric. The complaint cites songs such as “Eye of the Tiger,” “Livin’ On a Prayer,” and works by Mariah Carey and Taylor Swift, alleging Anthropic obtained the lyrics from pirate sites like Library Genesis and Pirate Library Mirror.
