OpenAI has announced a plan to expand access to AI models with advanced cyber capabilities while implementing controls on who can use them. The move coincides with the release of a new model variant, GPT-5.4-Cyber, designed to assist with defensive cybersecurity tasks and be more permissive for vetted users. OpenAI plans to expand this model's access to thousands of individuals and hundreds of security teams through its Trusted Access for Cyber program, provided they complete verification checks. The rollout will be gradual, with initial access limited to vetted security vendors, organizations, and researchers, but it is expected to scale over time. The rapid pace of AI tools' advancement is causing concern among government officials and global business leaders.
