Researchers say OpenAI revoked their access to limited cyber program

“OpenAI recently revoked access for several vetted security researchers to its Trusted Access for Cyber (TAC) program, citing a technical issue that affected a limited number of users. The affected researchers, all based outside the U.S. and Europe, lost access to the Daybreak Blue tier, which provides advanced models like GPT‑5.6 Sol for defensive security work. OpenAI has asked the users to re‑verify their identities and reapply for the program. The incident highlights the fragility of access controls for high‑impact AI tools and raises questions about consistency in OpenAI’s vetting process. Expert Analysis: The temporary loss of TAC access could slow vulnerability discovery for U.S. firms that rely on external security researchers, potentially widening the gap between defensive and offensive AI capabilities. If OpenAI tightens regional eligibility, American companies may need to invest more in in‑house AI security talent, reshaping the domestic cybersecurity talent market.”
