Sam Altman revealed the back of OpenAI's Navier-Stokes milestone shirt — instead of equations, it prints the literal last line of the chain-of-thought from the model's solution: "Remark solving millennium forced case unbelievable; reviewers likely hostile."

The model apparently anticipated academic skepticism while solving a Millennium Prize Problem, and the line becoming official merch (reposted by roon, 226K views) has become the AI community's latest iconic moment.
