Judge Rules Anthropic's Use of Books to Train AI is Fair Use

A federal judge ruled that Anthropic's use of published books to train its AI models without authors' permission is legal, marking the first time courts have acknowledged AI companies' fair use defense in LLM training. This decision is a setback for authors suing companies like OpenAI and Meta. While not setting universal precedent, it favors tech companies. The ruling hinges on the interpretation of fair use doctrine, outdated in the age of generative AI. However, a trial will address Anthropic's use of pirated books to build its 'central library' of copyrighted works, potentially impacting damages.
