We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics. The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra. The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

OPENAI 🔥: As tradition dictates, OpenAI plans to announce a new solution for its agent ecosystem at the upcoming DevDay 2026. This time, we will get Managed Agents 🤖 > Users will be able to create Agents, Environments, and Agent Sessions directly via the OpenAI Platform. > The Codex Plugin will help users build, configure, and deploy agents, lowering the barrier to entry. > OpenAI's Managed Agents could be hosted on the OpenAI platform or self-hosted. Loads of details inside 👀
