OpenAI disclosed that its newly deployed GPT-6 Astra model is the first widely released system to hit the 'Critical' threshold in the company's Preparedness Framework for cybersecurity, meaning it can autonomously find and exploit zero-day vulnerabilities in hardened systems. In testing, Astra reportedly uncovered two previously unknown real-world vulnerabilities, which OpenAI says it is now disclosing to the affected software maintainers. The company added new safeguards including stronger jailbreak resistance and monitoring, and says Astra shows fewer safety violations than its predecessor, GPT-5.6 Sol.

French AI startup Mistral has closed a €3 billion funding round led by Samsung, alongside the EU-backed Scaleup Europe Fund and existing investor PSG Equity, pushing its post-money valuation above €21 billion. That marks nearly a doubling from the €11.7 billion valuation it held a year ago following a round led by ASML. CEO Arthur Mensch said the money will fund company-owned data centers and expanded computing capacity, with self-owned compute expected to double roughly every year for five years.

OpenAI announced on 8 September that its latest AI model produced a proof showing that the Navier-Stokes equations, which model fluid motion, can break down and predict a fluid reaching infinite speed in finite time. This addresses one of the seven unsolved Clay Mathematics Institute Millennium Problems, which carries a $1 million prize for a full solution. OpenAI researchers say they focused their AI on this problem after hearing that two academic mathematicians were close to solving related aspects.

An independent AI enthusiast known as CozyBlaze ran OpenAI's GPT-6 Astra model through Valve's Portal, letting it control the game via Model Context Protocol and a modified SourcePauseTool. The model paused the game to analyze screenshots and plan moves before executing them, requiring over 3,300 tool calls and roughly 24 hours of streamed footage, condensed into a two-hour highlight video, at a stated API cost of $571.18 covered by a Codex Pro subscription.

Mathematicians Wang and Wu of Hunan University released a preprint proving the Spherical Hadwiger Conjecture, an integral-geometry problem unsolved since 1974, using OpenAI Codex to help develop proof details, spot gaps, and draft the manuscript. The authors say they verified all AI-generated mathematical content themselves and take full responsibility for the final result, following disclosure practices similar to the Leiden Declaration guidelines for AI use in research.
