The United States District Court for the Northern District of California has handed down a ruling that using legally acquired copyrighted materials to train AI models falls within the realm of fair use, a decision that endorses the practices of Anthropic. However, the court also highlighted that Anthropic's separate action of downloading millions of pirated books from unauthorized websites for AI training purposes constitutes copyright infringement. This ruling has ignited a debate about creators' rights, raising concerns that it may jeopardize professionals in the creative industries, including artists, musicians, and writers, and exacerbate the issue of AI companies commercially exploiting original content without permission.
