Mark Chen denies OpenAI accessed user data in Navier Stokes effort
Mark ChenOpenAI researcher explaining the company's process on his account
Separates a denial of targeted access during the project from acknowledged use of de-identified data and feedback to improve products.
Responding to
OpenAI says its researchers and agents did not access Buckmaster and Alpöge's unpublished work for the project.
“Did any human or agent look at user data as part of the Navier Stokes effort? No.”

Where this statement fits
Did OpenAI improperly pressure mathematicians over authorship and credit?
Tristan Buckmaster describes pressure over authorship and publication during discussions about competing AI-assisted mathematics results. Sébastien Bubeck disputes that characterization and says the proposed authorship concerned OpenAI's own proof. His apology for career-related wording does not settle the disagreement. Researchers and commentators divide over whether the negotiations were appropriate, while raising a separate dispute about the treatment of unpublished user research.
