The artificial intelligence company Anthropic achieved a partial victory in the AI training data copyright case.

Gate News bot reports that, according to Decrypt, the artificial intelligence company Anthropic has won a key legal victory in a copyright dispute over how AI companies use copyrighted materials to train their models, but the fight is far from over.

In a ruling on Monday evening, U.S. District Judge William Alsup determined that Anthropic's use of copyrighted books to train its AI chatbot Claude qualifies as "fair use" under U.S. copyright law.

U.S. District Judge William Alsup ( stated in his ruling: "Like any reader who aspires to be a writer, the training purpose of Anthropic's law master's program is not to surpass, replicate, or replace works, but to break through dilemmas and create something different."

But the judge also accused the company, supported by Amazon and Google, of establishing and maintaining a large pirated book "central library," stating that this behavior clearly infringes on copyright.

The case was brought last August by authors Andrea Bartz ), Charles Graeber (, and Kirk Wallace Johnson ), alleging that Anthropic used millions of pirated books downloaded from notorious sites like Library Genesis and Pirate Library Mirror to create Claude.
