Fired OpenAI Researchers Dispute Misconduct Claims, Warn of Chilling Effect

Three OpenAI safety researchers, Jasmine Wang, Tomek Korbak, and Mikita Balesni, who were fired last week, have published an open letter denying allegations of mishandling sensitive information. They warn that their dismissal creates a chilling effect that stifles AI safety work and open dialogue within the company. The researchers say they acted in good faith and within company norms, and that the reasons for their firing are unclear. They urge OpenAI to uphold its commitments to third-party safety auditors and maintain a transparent culture. OpenAI responded with an internal memo denying retaliation and stating that employees are not terminated for raising concerns, but did not address specific policy violations or circumstances of the dismissal. The dispute highlights tensions between internal safety research and company communication policies at a time when OpenAI faces scrutiny over safety incidents.
