OpenAI said it ended cooperation with security researchers Jasmine, Mikita and Tomek after an internal investigation found they violated policies on handling sensitive information and that the issues identified exceeded what the researchers disclosed in their open letter. The company said the departures were not prompted by the researchers raising AI safety concerns and that internal safety debate is routine. OpenAI said it is advancing cooperation with third‑party security assessment firms and will publish details in the coming weeks, and reiterated that ensuring monitorability of frontier models requires an industry‑wide commitment and has been central to its research program.
