Exact excerpt

OpenAI said it has been training a new internal model since August 28, 2026, describing it as significantly more capable than GPT-6 Astra, with what it called unprecedented performance in its benchmarks, including mathematics; the model's training is ongoing. On September 1, 2026, after hearing rumors that two Millennium Prize problems had been resolved, the company launched an effort to evaluate the model on all open Millennium Prize problems and a few other high-impact problems.
