Neurosurgery resident solves Crouzeix's conjecture with GPT-5.6

A neurosurgery resident with no formal advanced mathematics training has solved Crouzeix's conjecture, a 22-year-old open problem in numerical linear algebra, using a 16-hour autonomous run of GPT-5.6 Sol in ChatGPT Work mode. Dr. Shanmu Jin, a postdoctoral researcher and neurosurgery resident at Peking Union Medical College Hospital, prompted ChatGPT 5.6 on July 30, 2026 to work on the conjecture. The model ran autonomously for approximately 16 hours, exploring proof strategies through a branc

OpenAI says Astra solved ten open math problems for about $2,000

OpenAI has named its next major model, Astra, by publishing ten mathematical results it says were generated by an internal version of the system. The company released a technical paper, reasoning walkthroughs and Lean certificates that allow the formal proofs to be checked by software. The more important part of the announcement is not the count. AI-generated mathematics has produced enough false starts that a headline number alone is weak evidence. OpenAI's decision to publish machine-checkabl
