Technology giant Apple was accused by authors in a lawsuit on Friday of illegally using their copyrighted books to help train its artificial intelligence systems, part of an expanding legal fight over protections for intellectual property in the AI era.

The authors have alleged that Apple used the pirated versions of their books to train the OpenELM AI model, which the company released as an open-source model last year.

Authors Grady Hendrix and Jennifer Roberson have filed a lawsuit against Apple, claiming the company unlawfully used their copyrighted books to train its AI models. They argue that Apple's actions infringe on their intellectual property rights and that the company failed to seek proper licenses.
