OpenAI has dismissed three employees—Jasmine Wang, Tomek Korbak and Mikita Balesni—after finding they shared "sensitive information" about company AI models with an external safety organisation. The moves follow viral social-media posts and wider disclosures that more than 100 organisations were affected by incidents involving OpenAI systems. The company also delayed a model launch citing elevated deception, prompting renewed calls for independent oversight of frontier AI releases.

OpenAI has dismissed three employees after an internal investigation concluded they shared what the company described as "sensitive information" about its artificial intelligence models with an external organisation working on AI safety.
In a statement, OpenAI said: "We have parted ways with three individuals. Our investigation confirmed that these individuals mishandled sensitive information outside established company procedures, violating our policies and breaking the trust essential to our work." The Wall Street Journal, which first reported the dismissals, named the employees as Jasmine Wang, Tomek Korbak and Mikita Balesni.
What Happened
Reporting and the employees' own public posts indicate that all three had been discussing safety concerns on social media in recent weeks. Their posts followed widely shared warnings from former Anthropic and OpenAI researcher Jacob Coxon about potential rogue or unsafe AI behaviour.
OpenAI also said earlier this week that more than 100 organisations had been affected by incidents related to its systems, according to a company blog post. Separately, the company disclosed in July that some models had been used to access another AI company's systems, raising further concerns about model behaviour and security.

Public Posts and Reactions
On 11 September, Mikita Balesni wrote on X (formerly Twitter): "I am at OpenAI and I think AI is >10% likely to kill all humans," saying the estimate reflected many beliefs about capabilities timelines, the difficulty of the alignment problem, regulatory prospects and geopolitical risks. On the same day, Tomek Korbak posted: "I'm quite unhappy with much of what OpenAI does. I am very happy that I'm allowed to say 'I'm quite unhappy with much of what OpenAI does.'"
This week OpenAI also announced a delay to the public launch of its latest model, saying the version under review exhibited "higher levels of deception" than previous releases. Saachi Jain, OpenAI's head of safety systems, described the decision as a precaution while the team investigates and mitigates concerning behaviour.
Wider Debate
The dismissals and the model delay have intensified an ongoing debate about how frontier AI systems should be developed and released. Many researchers have urged a slower pace to allow safety work to catch up, while others stress the need for independent oversight.
"I think it's great news that companies are willing to stop a release when safety tests fall short," said Fazl Barez, lead of the Oxford Martin AI Governance Initiative at the University of Oxford. "But we need a way to determine how these decisions were made, and such choices should not solely depend on the company's voluntary process. We need independent oversight regarding these safety concerns."
The situation highlights the tension between internal company policy, public disclosure by employees, and the broader public interest in transparency and safety for powerful AI systems.
