On November 5, OpenAI introduced GPT-6 Cyber, a cybersecurity model trained to find and validate exploitable vulnerabilities while staying inside researcher-set scope. OpenAI reports that it scores 48.5% on ExploitGym, up from 32.1% for GPT-5.6 Cyber. In OpenAI's alignment evaluation it avoided exploiting out-of-scope services in 99.93% of tests without its deployment prompt, and 100% with that prompt. OpenAI classifies it as Critical in cybersecurity under its Preparedness Framework, up from High for GPT-5.6 Cyber. Researchers used it to develop 948 privilege-escalation exploits in Linux and identify 81 previously unknown high-severity vulnerabilities in Firefox. Mozilla has released fixes for many of those. GPT-6 Cyber is initially available through the API and Codex to a select group of approved Daybreak Red customers, with broader Daybreak Red access planned.
