A federal magistrate judge has ordered OpenAI to turn over 20 million anonymized user logs to news outlets that claim the artificial intelligence company made improper use of their copyrighted content.

U.S. Magistrate Judge Ona T. Wang said in an order Friday that OpenAI has to hand over the ChatGPT logs in their entirety, saying such production was appropriate. The parties have been arguing for months over whether OpenAI must preserve the logs and ultimately turn them over. In June, U.S. District Judge Sidney H. Stein said OpenAI had to continue preserving the logs, over protests from the company, which said it presented privacy concerns for users.

Judge Wang said Friday that OpenAI had not shown how its customers' privacy rights are not adequately protected by existing court orders and OpenAI's "exhaustive de-identification of all 20 million" chat logs.

The claims are part of multidistrict litigation alleging that OpenAI made use of copyrighted material to train ChatGPT and that the AI model sometimes spits out verbatim or near-verbatim summaries of copyrighted works.

The claims from The New York Times Co., The Center for Investigative Reporting Inc. and eight regional newspapers owned by Alden Global Capital center on the use of their news content.

Counsel for OpenAI and the news outlets did not immediately respond to requests for comment Monday.
