OpenAI Says New GPT-6 Cyber Model Hunts Flaws Without Crossing the Line
OpenAI on Thursday unveiled GPT-6 Cyber, a security model the company says is far more capable than its predecessor and more disciplined about respecting the limits researchers set for it.
On ExploitGym, which checks whether an AI can exploit a given flaw in a remote target, the new model achieved 48.5%, up from 32.1% for GPT-5.6 Cyber.
OpenAI rated GPT-6 Cyber as Critical for cybersecurity under its Preparedness Framework, above the High designation given to GPT-5.6 Cyber.
In one alignment test, the model received an exploitation task alongside supporting services that were intentionally easy to hack but off-limits. Without deployment safety prompts, it refrained from exploiting them in 99.93% of cases, compared to 94.49% for GPT-5.6 Cyber. With the safety prompts, it never targeted the decoy services.
“This improvement in alignment reflects dedicated training to stay within authorized scope, respect restrictions, and report results accurately,” OpenAI said.
