OpenAI Launches GPT-5.6-Cyber and Expands Daybreak Cybersecurity Initiative

OpenAI announced the expansion of its Daybreak cybersecurity initiative and the release of GPT-5.6-Cyber, a new model built for advanced, authorized defensive security work. The company framed the release as a proactive step to put frontier AI capabilities in the hands of trusted defenders before attackers can leverage offensive AI at scale. GPT-5.6-Cyber is intended for tasks such as vulnerability analysis and incident response under strict authorized-use guardrails, reflecting a broader industry push to channel powerful models toward defensive rather than offensive security applications.
