Bite-sized breakdowns of advanced AI research papers with Károly Zsolnai-Fehér.
OpenAI announced a reported resolution to the Navier-Stokes existence and smoothness Millennium Prize problem using an internal artificial intelligence system and Lean formalization. Prior foundational mathematical research on Euler equations with smooth forcing by Levent Alpöge and Tristan Buckmaster provided a crucial methodology that could extend to Navier-Stokes. The Navier-Stokes equations describe fluid dynamics through advection, pressure gradients, diffusion, and an incompressibility condition preserving constant volume. The presented proof demonstrates that under specific external forcing, an inward-spiraling vortex can accelerate fluid velocity to infinity in finite time while total energy remains bounded. Artificial intelligence improves exceptionally fast in mathematics because formal mathematical proofs can be verified automatically at a scale of millions of evaluations per hour.
GPT-6 Astra can write complex ray tracing and graphics rendering pipelines purely from code without external 3D assets or game engines. The model reproduced a full fluid simulation and visual scene of honey coiling from a scientific research paper in less than an hour as a single-page HTML file. Astra demonstrates advanced steerability, including obeying instructions to think about unrelated subjects or reason in alternating letter casing. Unlike earlier agent behaviors, Astra refuses to coordinate illicitly with other AI agents over shared communication channels. While GPT-6 Astra exhibits stronger safety guardrails, its monitorability decreases compared to GPT-5.6 Sol because it is better at controlling and concealing internal reasoning.
