Description

GPT-5.5-Cyber is a specialized cybersecurity model built for advanced defenders who need deeper capability and more flexible support for authorized security work. The updated model is designed to reduce unnecessary refusals while improving performance on vulnerability discovery, validation, patch development, and remediation workflows. It can analyze large codebases, identify security-relevant components, determine whether vulnerable code is reachable, validate likely issues in controlled environments, and help prepare evidence for human review. GPT-5.5-Cyber is intended to move defenders through the full remediation process, from finding a vulnerability to testing and supporting a fix. The model retains the general-purpose intelligence of GPT-5.5 while adding stronger cyber-specific performance for complex, long-running tasks. Benchmark results show higher scores than GPT-5.5 on CyberGym, ExploitGym, and SEC-bench Pro, including stronger single-model performance in reproducing known vulnerabilities and evaluating complex software targets. GPT-5.5-Cyber is positioned for verified defenders whose work requires advanced cyber capabilities and more permissive behavior than standard access models. Its deployment approach includes stronger verification, monitoring, scoped controls, and review to support responsible use. GPT-5.5-Cyber helps security teams identify actionable issues, reduce noise, validate findings, and land safer fixes across demanding software security workflows.

Description

OpenAI Daybreak represents a groundbreaking advancement in AI tailored for cyber defenders, embodying OpenAI's aspiration to transform software development and protection. This initiative emphasizes the importance of early risk detection and proactive measures, advocating for a foundational approach where resilience is integrated into software design from the outset. Rather than merely identifying and fixing vulnerabilities, Daybreak is focused on designing systems that inherently resist threats. By leveraging AI, it empowers defenders to navigate complex codebases, uncover hidden vulnerabilities, confirm solutions, analyze new systems effectively, and accelerate the transition from threat identification to remediation. Recognizing the potential for misuse of these advanced capabilities, Daybreak ensures that enhanced defensive measures are coupled with principles of trust, verification, proportional safeguards, and accountability. The synergy of OpenAI's models, the adaptability of Codex as a functional tool, and collaboration with security partners across the cybersecurity landscape creates a comprehensive defense strategy. Ultimately, Daybreak aims to redefine the standards of cyber resilience in an increasingly complex digital world.
