01gpt-6 cyber: overview

What happened

On November 5 (US time) OpenAI released GPT-6 Cyber, a dedicated security model available at first only to a select group of approved customers in its Daybreak Red programme via the API and Codex, with wider Daybreak Red access planned. OpenAI says researchers used it to find 81 previously unknown high-severity Firefox vulnerabilities, for which Mozilla has begun shipping fixes. In Linux kernel research the model flagged 2,308 potential issues, reproduced 1,724 vulnerabilities and produced working local privilege-escalation exploits for 948 distinct flaws, against 166 for GPT-5.6 Sol in the same setup. It exploited 48.5% of vulnerabilities on ExploitGym, versus 32.1% for GPT-5.6 Cyber. Under its Preparedness Framework OpenAI rated the model's cybersecurity capability "Critical", up from "High".

Why it matters

It is the first OpenAI model rated Critical for cybersecurity, and it follows last week's Gemini 4 Carbon pattern of giving highly capable offensive-security models to vetted defenders first. OpenAI says that on its ExploitGym Honeypot scope test GPT-6 Cyber left out-of-bounds services alone in 99.93% of runs without its deployment safety prompt (GPT-5.6 Cyber: 94.49%), and that it has disclosed 304 critical Linux findings to maintainers with proposed patches. Security commentators note that even a small out-of-scope rate means unauthorised actions on real systems, and a lower bar for vulnerability research shortens the window defenders have to patch.

Who it affects

Security teams and red teams, open-source and operating-system maintainers, critical-infrastructure operators, and enterprises using the OpenAI API and Codex.
