Scaling Trusted Access for Cyber with GPT-5.5 and GPT-5.5-Cyber

New specialized AI models target critical infrastructure protection with trusted access.

Deep Dive

OpenAI has expanded its Trusted Access for Cyber program with GPT-5.5 and GPT-5.5-Cyber, helping verified defenders accelerate vulnerability research and protect critical infrastructure.

Key Points
  • GPT-5.5 and GPT-5.5-Cyber are restricted to verified cybersecurity defenders only.
  • GPT-5.5-Cyber is fine-tuned on vulnerability databases, exploit patterns, and incident response data.
  • Early testing shows accelerated vulnerability research and improved critical infrastructure protection workflows.

Why It Matters

Domain-specific, access-controlled AI can radically speed up cyber defense without empowering attackers.
