Buckmaster and Alpöge, using Sol and Claude, prove smooth-forced blowup for Euler, IPM, and Boussinesq
On 8–11 September 2026 Tristan Buckmaster and Levent Alpöge released Lean-backed finite-time blowup results with smooth forcing for incompressible porous media, 2D Boussinesq, and 3D Euler, crediting Anthropic’s Claude and especially OpenAI’s GPT-5.6 Sol. Astra was used only for writeups and auditing.
OpenAI claims a forced Navier–Stokes singularity from an unreleased system
On 8 September 2026 OpenAI published a 166-page writeup and Lean formalization arguing that smooth, finite-energy 3D Navier–Stokes dynamics with a smooth external force can blow up in finite time, which it says settles Clay statements C and D. The search model was an unreleased internal system; GPT-6 Astra did the Lean step.
An unreleased OpenAI system produces an unforced 3D Euler blowup
While probing Millennium problems in early September 2026, OpenAI says a multi-agent run of an internal model more capable than GPT-6 Astra produced a finite-time singularity for unforced 3D incompressible Euler in about 50 hours.
GPT-6 Astra improves short and large prime-gap bounds
On 3 September 2026 OpenAI released GPT-6 Astra with two analytic number-theory results: a proof that infinitely many consecutive primes differ by at most 186, and an improvement to a large-gap bound that had been stuck for more than 80 years.
Pre-release GPT-6 Astra solves five Bloom-curated Erdős problems in Lean
On 1 September 2026 Epoch AI reported that a pre-release GPT-6 Astra system was the only model to score on FrontierMath Erdős, a Lean benchmark of 68 significant unsolved Erdős problems. It solved problems 74 and 126 under the official $300 protocol, and problems 1, 548, and 571 in extra attempts.
Freitag and Mutchnik, using ChatGPT 5.6, counterexample the stable forking conjecture
On 31 August 2026 James Freitag and Scott Mutchnik posted arXiv:2609.00436, a counterexample to the 1996 Hart–Kim–Pillay stable forking conjecture, found using ChatGPT 5.6.
