Authors sue Anthropic for allegedly using pirated books to train Claude, its AI model

Anthropic, the startup behind AI chatbot Claude, has been sued over alleged copyright infringement for the second time. The class action lawsuit was filed by three authors, Andrea Bartz, Charles Graeber and Kirk Wallace Johnson, in a federal court in California, United States of America (US), on Monday, August 19.

The lawsuit alleges that the Amazon-backed venture “built a multibillion-dollar business by stealing hundreds of thousands of copyrighted books,” including the authors’ works.
