About

GPT-5.6-Cyber is OpenAI’s most advanced purpose-trained cybersecurity model for approved defenders conducting authorized vulnerability research, exploit validation, and security testing. Built on GPT-5.6 Sol, it is trained to improve performance on specialized cybersecurity tasks such as finding zero-day vulnerabilities, developing exploit chains, testing authentication bypasses, privilege escalation, and advanced security research. The model is designed to reduce unnecessary refusals on legitimate higher-risk, dual-use cybersecurity work while helping trusted defenders conduct real-world security activities. GPT-5.6-Cyber improves performance on exploit development workflows and can generate proof-of-concept exploits alongside technical findings, assess the severity and impact of novel vulnerabilities, and support vulnerability discovery and report writing. It is particularly suited to sustained reasoning across large and unfamiliar codebases.

About

OpenAI Daybreak is frontier AI for cyber defenders and OpenAI’s vision for changing the way software is built and defended. Daybreak means seeing risk earlier, acting sooner, and helping make software resilient by design, starting from the premise that the next era of cyber defense should be built into software from the beginning. It is not only about finding and patching vulnerabilities, but about helping systems become resilient to them by design. Daybreak brings AI into modern cyber defense by helping defenders reason across codebases, identify subtle vulnerabilities, validate fixes, analyze unfamiliar systems, and move from discovery to remediation faster. Because those same capabilities can be misused, Daybreak pairs expanded defensive capability with trust, verification, proportional safeguards, and accountability. It combines the intelligence of OpenAI models, the extensibility of Codex as an agentic harness, and security partners across the security flywheel.
