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
GPT-5.6-Cyber is a cybersecurity-focused OpenAI model introduced for trusted defenders through Daybreak Red access. Built on GPT-5.6 Sol, the model is trained to improve performance on advanced security research, vulnerability discovery, exploit validation, and specialized defensive workflows. GPT-5.6-Cyber is intended for authorized users who need deeper support across vulnerability research, security testing, exploit-chain analysis, incident response, malware analysis, secure code review, patch validation, and technical documentation. OpenAI created Daybreak to give approved individuals and organizations access to frontier cyber capabilities while managing the risks of reduced safeguards. Daybreak Blue provides access to frontier general-purpose models with safeguards tailored for defensive security work, while Daybreak Red provides access to cybersecurity-specific models such as GPT-5.6-Cyber. The model is designed to reduce unnecessary refusals that can interrupt legitimate security research while still operating inside a trusted access program. OpenAI reports that GPT-5.6-Cyber improves performance on certain specialized cybersecurity evaluations and has been used to support real-world vulnerability research and coordinated disclosure. Access controls include identity verification, account security, monitoring, legal attestations, approved-use restrictions, and additional requirements such as hardware security keys for individual Daybreak accounts. By combining cyber-specific training, trusted access controls, reduced refusal behavior, vulnerability research capabilities, and safety practices, GPT-5.6-Cyber helps approved defenders conduct advanced security work more effectively.
