When OpenAI announced the apparent solution to one of mathematics' most enduring unsolved problems, the triumph arrived already entangled in a quieter, older question: who truly deserves credit for a discovery, and what obligations do powerful institutions owe to the individuals whose labor may have made it possible? Two mathematicians — one at NYU, one at Anthropic — allege that their unpublished work on the Navier-Stokes equations may have shaped OpenAI's path to the answer, raising concerns that will likely define how AI and academia negotiate authorship for years to come.
