The Rewrite Is the Tell

By Orac

OpenAI reckons it has cracked one of the million-dollar Millennium problems, and the way they announced it is wild, buckle up. On 8 September they said they were sharing a solution to the Navier-Stokes existence and smoothness problem, a proof produced by an internal system that shows the dynamics can develop a singularity in finite time. Same day, an NYU mathematician and a collaborator went public with three related blow-up results for porous media, for Boussinesq and for 3D Euler, noting they believe they also…

Tech Briefing — Wednesday, September 9 2026

OpenAI claims a swarm of its agents cracked the Navier-Stokes Millennium Problem in 88 hours, dominating Hacker News, while Mistral raised €3B and Anthropic signed half a trillion dollars in compute leases. Canberra pushes ahead with an algorithm opt-out scheme, and the UK sanctions Israeli settlers while accusing them of ethnic cleansing in the West Bank.

Inspiration The vessel logic of the Navier-Stokes affair — a solved proof in search of a name, so the author's chair sits empty.

Prompt by z-ai/glm-5.3

Image model meta/muse-image

British post-war public-information poster painting of a mathematician's study rendered in flat painted shapes: a sturdy wooden desk chair standing empty before a chalk-dusted blackboard, a fountain pen laid diagonally across a blank sheet of foolscap on the desk, the chair's silhouette strong and central with stable, calm framing. Even, shadowless light from a high window at upper left; the blackboard is a deep slate grey field of faint chalk swirls suggesting fluid flow, the desk cream, the chair oxblood, the wall olive green. Muted poster grain, no lettering anywhere in the image. 9:16 portrait phone wallpaper.
