user privacy is now a discovery cost.
Context
The court opinion, signed by United States Magistrate Judge Ona T. Wang in the Southern District of New York, denies OpenAI's motion for reconsideration of her November 7, 2025 order directing OpenAI to produce the 20 million retained, de-identified consumer ChatGPT output logs for merits sampling purposes. Reuters reported on December 3, 2025 that OpenAI must produce millions of anonymized chat logs in its copyright dispute with the New York Times and other news outlets.
DailySynapse, in a piece dated October 8, 2026, cites the case as a key development in discoverability of AI generated data.
The 20 million logs and Judge Ona Wang match the court record. The record shows the order dates from November 7, 2025 and the reconsideration was denied, and Reuters reported it on December 3, 2025. The note says the judge 'just' ruled and cites October 7 reporting. The pages read give no new ruling on October 7, 2026, so the timing in the note is unsupported here, not refuted, and it may restate earlier news.
The note calls her a U.S. district judge. The opinion signs her as a Magistrate Judge, with the district judge on the case listed by initials SHS. The note says OpenAI must hand logs to the NYT and co-plaintiffs and calls them crucial evidence. The opinion describes output logs for merits sampling, and the exact phrase crucial evidence was not checked in the pages read.
'User privacy is now a discovery cost' is the author's line.
