OpenAI releases GPT-6 Cyber and rates its hacking skill as critical

OpenAI has released GPT-6 Cyber, a model built to find software flaws and write working exploits. It is the first model OpenAI rates as critical for cybersecurity under its own safety framework. Because of that rating, only vetted organisations in its Daybreak Red programme can use it. They must verify identity and meet strict account security rules.

On the ExploitGym benchmark, which tests turning known bugs into working attacks, the model succeeded in about 48 percent of tasks. Its predecessor managed about 32 percent. OpenAI also rates it high for biological and chemical risk. Safeguards include sandboxed use, monitoring for misuse, and blocking help against industrial control systems and essential services. The benchmark figures come from OpenAI itself and have not been checked independently.
