"OpenAI Inc. will have to turn over 20 million anonymized ChatGPT logs in a consolidated AI copyright case after it failed to convince a federal judge to throw out a magistrate judge’s order the company said insufficiently weighed privacy concerns.

Magistrate Judge Ona T. Wang sufficiently considered privacy concerns against the material’s relevance to the ongoing litigation in her discovery ruling in favor of news organization plaintiffs in five lawsuits, District Judge Sidney H. Stein said in an order Monday. She rejected OpenAI’s arguments it should be allowed to run a search of the 20 million-log sample and produce conversations implicating the plaintiffs’ works, saying no case law requires the court to order the least burdensome discovery possible."

"OpenAI Inc.'s tactical win consolidating a dozen copyright suits against it nevertheless carries risks for the company, as the matters proceed before a judge who’s already ruled against the company in key decisions.

The US Judicial Panel on Multidistrict Litigation last week centralized casesacross the country in the US District Court for the Southern District of New York for pretrial activity, which could include dispositive motions including summary judgment, as well as contentious discovery disputes that have been common among the cases.

“This will help create more consistency in the pre-trial outcomes, but it also means that you’ll get fewer tries from different plaintiffs to find a winning set of arguments,” Peter Henderson, an assistant professor at Princeton University, said in an email...

While streamlined, the pretrial proceedings figure to remain contentious as the parties press novel questions about how copyright laws apply to the game-changing generative AI technology. The disputes carry vast ramifications for companies reliant on millions of copyrighted works to train their models."
