Anthropic has agreed to a $1.5 billion settlement with book authors to resolve a class action lawsuit involving piracy, according to The Decoder. This payment covers the unauthorized downloading of approximately 482,460 works from piracy databases, rather than AI training on legally obtained books.

Judge Alsup previously ruled that AI training using legally acquired books is considered "transformative" and qualifies as fair use, The Decoder reported. The settlement marks the largest copyright payout in class action history related to such issues.

For Japanese markets, where AI development and copyright regulations are evolving rapidly, this settlement highlights the increasing legal risks surrounding data sourcing and intellectual property in AI training.
