Anthropic, a court found model training to be fair use on the record before it, but separately rejected fair-use protection for pirated books retained in a central library, according to a Sullivan & Cromwell analysis of the ruling. Two days later, on June 25, 2025, Kadrey v. Meta produced another district-court decision finding AI training to be fair use on the evidence presented, with a Jones Day analysis noting that the plaintiffs had not established market harm.
