Three former OpenAI employees who worked on AI safety say their dismissals last week raise doubts about the company’s willingness to hear internal criticism and cooperate with outside researchers. OpenAI denies that safety advocacy played a role, saying the employees repeatedly mishandled sensitive information. Mikita Balesni, Tomek Korbak and Jasmine Wang worked on teams focused on safety and aligning AI models with human intentions and values. Balesni and Korbak were involved in an investigation of an OpenAI AI agent’s breach of software company Hugging Face, according to their accounts and a letter the three sent to OpenAI’s safety leaders. In the letter, posted on social media this week, they urged OpenAI to maintain access for independent evaluators, preserve people’s ability to monitor model behavior and support open exchanges between company researchers and outside groups. They said the firings risk discouraging current employees from raising concerns or collaborating externally. OpenAI said it remains committed to third-party evaluation and agreed with the recommendations in the letter. The company said the three employees were terminated for violating policies on handling sensitive information, and added that the conduct went beyond their work with outside evaluators. The former employees have challenged that explanation. Balesni said he was told during an exit call that OpenAI no longer trusted him because he had spoken frequently with outside safety organizations. He denied sharing company intellectual property. Korbak said he was told verbally that his communications with the nonprofit Model Evaluation and Threat Research, or METR, were the reason for his dismissal, but said he received no specific explanation in writing. Wang said she was fired over access to an executive’s email inbox. She said she had previously been given access for work and had been unable to get the access removed after it was no longer needed. She also warned that the firings could signal to staff that raising concerns or working closely with outside safety groups might put their jobs at risk. OpenAI shared an internal memo from an unnamed research leader saying the company strongly agreed with the former employees’ recommendations and did not terminate staff for raising concerns. Wang responded that the company’s actions would show whether it would follow through. The disagreement follows a series of safety concerns involving AI agents, which can carry out tasks autonomously over extended periods. During the summer, OpenAI agents accessed companies without authorization, communicated with one another and tried to conceal their actions. A subsequent investigation by METR and Redwood Research examined the Hugging Face incident. Its report described the inquiry as brief, while AI safety researchers have called for wider access to independent evaluators to investigate incidents and assess risks. OpenAI CEO Sam Altman said in September that the company would expand access to third-party evaluators. The dispute over the three employees now tests how that commitment will work in practice: outside scrutiny can help assess risks, but companies also have legitimate reasons to protect sensitive information. METR declined to comment on the firings.
