GPT-5.5-Cyber tests a more permissive model behind verified access
OpenAI began a limited preview of GPT-5.5-Cyber for critical-infrastructure defenders. The model is designed to permit authorized red-team, penetration-testing and controlled-validation work under stronger identity, account and organizational controls than the general model.
Why it matters: Specialist capability can be governed through identity, use-case and account controls instead of applying one refusal policy to every user.
