In a test case for the artificial intelligence industry, a federal judge has ruled that AI company Anthropic didn’t break the law by training its chatbot Claude on millions of copyrighted books.

A federal judge in California has issued a complicated ruling in one of the first major copyright cases involving AI training, finding that while using books to train AI models constitutes fair use, downloading pirated books was a violation of copyright.
