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.

ChatGPT — v61.5M+ context window points to much longer context handling across documents, codebases, and persistent sessions. A new pre-training foundation suggests a deeper base-model reset rather than a small iterative checkpoint. Rumored 10T-scale training implies broader capability coverage and stronger knowledge compression. Substantial agentic gains point to better tool use, task planning, and multi-step execution. Stronger reasoning aimed above current top tiers implies better performance on difficult chained problem-solving tasks.
