Putting frontier cyber models in more trusted hands

OpenAI has released GPT-5.6-Cyber, a specialized model integrated into its Daybreak Red platform designed for authorized security testing and vulnerability research. By successfully addressing 98.5 percent of security queries that were previously restricted, the model aims to provide defenders with a tactical advantage in identifying threats. This tool has already assisted in the discovery of two previously unknown Chrome vulnerabilities, signaling a shift toward using generative AI to proactively close exploit windows before attackers can leverage them.
