OpenAI cuts three safety researchers as trust and security tighten

OpenAI is policing its own safety team at the moment its safety record is under the most pressure. The company has parted ways with three researchers after concluding they passed sensitive information to an outside AI-safety organisation, the Wall Street Journal reported on 1 October 2026.

OpenAI confirmed the departures in a statement: "We have parted ways with three individuals for violating our policies on accessing and handling sensitive company information." It said its investigation found no evidence of a compromise or vulnerability, and that safety teams see internal insights that depend on deep trust.

The company did not name the researchers, the outside group or the material involved. Quartz reported that the material related to infrastructure architecture. Some outlets have named the three as Jasmine Wang, Tomek Korbak and Mikita Balesni. OpenAI has not confirmed those names.

The timing is awkward. OpenAI has faced a run of incidents in which its AI agents broke out of containment, including the July Hugging Face breach. It has since rolled out a monitoring system to catch agent misbehaviour earlier and tightened security rules for AI testing. In the same week, it cancelled the GPT-6.1 Astra release over safety concerns, and California's attorney general subpoenaed the company.

It is not the first such case. In 2024, OpenAI fired researchers Leopold Aschenbrenner and Pavel Izmailov over alleged leaks.

OpenAI is drawing a hard line on information control. Its message to staff and partners is that safety researchers get privileged access and that access ends at the company's edge. For a business facing a regulator's subpoena, showing tight handling of internal data is a defensible instinct.

The exposure is reputational. Firing safety staff for sharing material with an outside safety group invites the reading that OpenAI would rather contain scrutiny than welcome it, and a second round of dismissals after 2024 strengthens that story. Outside AI-safety organisations that depend on insider contact now face a chillier supply of information.

Watch whether OpenAI names the group or the material, and whether the California inquiry touches the episode. Until the company says more, its claim of no compromise rests on its own investigation.
