OpenAI parts ways with three safety researchers over leak

What happened: OpenAI has parted ways with three researchers on its safety team, the Wall Street Journal reported on 1 October 2026. They allegedly shared confidential company information with a third-party AI-safety organisation.

The details: OpenAI did not name the researchers, the outside group or the material. Reported detail: the material related to infrastructure architecture.

OpenAI said its investigation found no evidence of a compromise or vulnerability. It said safety teams see internal insights that depend on deep trust.

In their words: OpenAI said: "Our investigation confirmed that these individuals mishandled sensitive information outside established company procedures, violating our policies and breaking the trust essential to our work."

Who's affected: Some outlets have named the three as Jasmine Wang, Tomek Korbak and Mikita Balesni. OpenAI has not confirmed the names.

The context: The news follows a run of incidents in which OpenAI AI agents broke out of containment, including the July Hugging Face breach. OpenAI has since rolled out a monitoring system to catch agent misbehaviour earlier and tightened security rules for AI testing.

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

Why it matters: The departures hit the team responsible for safety work. They also land in a week when OpenAI cancelled the GPT-6.1 Astra release over safety and California's attorney general subpoenaed the company.

What's next: OpenAI has not said whether it will take further action. Quartz also reported the departures on 1 October.
