OpenAI’s new security model is for ‘critical cyber defenders’ only

OpenAI is set to launch its new cybersecurity model, GPT-5.5-Cyber, as announced by CEO Sam Altman. This model will initially be rolled out to a select group of 'cyber defenders' to help institutions strengthen their cyber defenses. The limited rollout is expected to begin 'in the next few days,' with Altman stating that OpenAI will collaborate with the government and the ecosystem to determine trusted access. The specific entities receiving access first remain undisclosed, but past initiatives involved vetted professionals and institutions.
