What happened

USA Today Co., along with several local newspapers it owns, has filed a copyright lawsuit against OpenAI. The publisher claims OpenAI copied "hundreds of thousands" of its articles to train its AI models.

How much is at stake

In a filing on Thursday, the publisher is seeking more than $250 million in damages. According to the company, the unauthorized use of its content has caused "real and continuing" harm to its outlets.

Why it matters

The case is the latest in a string of copyright lawsuits filed against OpenAI. The New York Times, The Intercept, CNET owner Ziff Davis and CBC/Radio-Canada are among the publishers that have also taken legal action against the company.

How training data is treated under copyright law remains one of the biggest open questions for the AI industry.
