WASHINGTON - The National Bureau of Filed Discoveries does not seat a math-result filing until a laminated KEEP UP card has hung overnight on the duty window and 372 identical packets sit stamped UNREAD in the intake tray. Duty clerk Ames said the morning count takes the filing only when both are still in place. "The card has to be up when the night log closes, and it has to be up when we open," Ames said. "372 UNREAD means 372. A packet with a lifted flap goes back to the shelf." On 6-7 October 2026, OpenAI published 722 mathematical manuscripts in 372 result families on GitHub, in the repository openai/math. The manuscripts came from an unnamed internal frontier model. OpenAI said each result took about three hours of ChatGPT Pro Thinking on average, and that about 4,000 problems were attempted. The company said it wants the math community time to assess the papers and is exploring community-hosted alternatives. Scientific American and other trade coverage said the company claimed almost every result came from a single prompt to a single agent. The coverage described an earlier claimed Navier-Stokes effort, which it said used a large agent swarm, and mentioned claimed progress toward the Riemann hypothesis and other hard problems. Verification of those claims is uneven in public write-ups. Ames locked the intake tray at the end of the shift. The KEEP UP card stayed on the duty window, and the 372 packets remained stamped UNREAD.
