GPT‑6 Cyber ships with ExploitGym at 48.5%, up from 32.1%, and 99.93% avoidance of out-of-scope exploitation
OpenAI released GPT‑6 Cyber for security research, scoring 48.5% on ExploitGym, which tests whether a model can exploit a specified vulnerability, up from 32.1% for GPT‑5.6 Cyber. In a separate alignment evaluation, the model avoided exploiting out-of-scope services in 99.93% of tests without its deployment prompt, versus 94.49% for GPT‑5.6 Cyber, and reached 100% with the prompt. OpenAI says it has been used to develop 948 privilege escalation exploits in Linux and to find 81 previously unknown high-severity vulnerabilities in Firefox.
