OpenAI Ships GPT-6 Cyber to Approved Customers Only

OpenAI released GPT-6 Cyber on 5 November, scoring 48.5% on ExploitGym against 32.1% for the previous cyber model, finding 81 previously unknown high-severity flaws in Firefox, reproducing 1,724 Linux kernel bugs with working privilege escalation for 948 of them, and cutting its unsafe-action rate to 0.07% from 5.51%. It is rated critical, sold at $20 and $100 per million tokens to certified customers only, and backed by a $1 billion defender fund. The Astra and Sol models did not ship, which settles an earlier rumour in the negative.
