Amazon-Backed AI Company Agrees to ‘Guardrails’ On Using Copyrighted Lyrics to Train Claude AI Product

By Michelle Morgante
February 01, 2025

Music publishers have reached a partial agreement with Anthropic that requires the Amazon-backed artificial intelligence company to implement “guardrails” around its use of copyrighted song lyrics to train its flagship product, Claude.

The agreement signed last month by U.S. District Judge Eumi Lee in the U.S. District Court for the Northern District of California addresses only part of the copyright infringement suit. The parties continue to dispute Anthropic’s alleged misuse of 500 copyrighted song lyrics that plaintiffs contend were used to train Claude’s large language model.

The partial deal requires Anthropic to maintain already-implemented guardrails to “prevent infringing outputs of copyrighted content, including publishers’ works,” it said.
The publishers include major music companies such as Concord Music Group, Capitol CMG, Universal Music, Polygram and ABKCO Music. They are represented by attorneys from Oppenheim & Zebrak of Washington, DC, and New York and Coblentz Patch Duffy & Bass of San Francisco.
