By OpenAI
Model family: GPT
GPT-5.5-Cyber is a limited-preview model for specialized defensive cybersecurity work that needs more permissive behavior than standard GPT-5.5 access. OpenAI positions it for authorized workflows such as red teaming, penetration testing, controlled validation, and advanced vulnerability research, especially for defenders responsible for critical infrastructure. It is not mainly presented as a more capable model than GPT-5.5, but as a cyber-permissive variant paired with stronger verification, misuse monitoring, approved-use scoping, and account-security requirements.
