OpenAI has dismissed three researchers following an internal investigation into their handling of sensitive information — a move the former employees say could discourage others at the company from speaking openly.

The company announced the firings of Jasmine Wang, Tomek Korbak and Mikita Balesni in a post on X on Friday, saying the three violated clear company policies identified during the probe.

“A note from our research leaders: Last week we parted ways with Jasmine, Mikita, and Tomek after a thorough investigation found they violated clear policies on handling sensitive information. Our internal investigation uncovered a significant breach of trust beyond what’s…” — OpenAI Newsroom (@OpenAINewsroom) 9, 2026

OpenAI said the investigation uncovered what it called a breach of trust. The company has not shared full details of what the researchers did wrong, and with no specifics public, the story currently rests on two competing accounts: OpenAI’s, centered on information handling, and the researchers’, centered on safety advocacy.

What the Researchers Say

The three former employees published their own letter on Thursday, a day before OpenAI’s statement, sending it to OpenAI’s board members and its safety committees — a step that takes the disagreement beyond a private personnel matter. In the letter, they argued that their sudden dismissal could make other employees afraid to speak up, saying open debate about safety had always been part of working at OpenAI.

Balesni wrote on X that he believed the firings happened because the group prioritized safety over the company’s short-term business interests.

The researchers also said they were not behind a news article published last month that covered security concerns tied to OpenAI’s newest AI model, known as Astra.

OpenAI’s Response

OpenAI pushed back directly on the idea that safety concerns led to the dismissals. The company said debates about safety happen daily inside OpenAI and are treated as a normal part of the job, and that no employee has ever been let go for raising concerns.

OpenAI added that it agrees with the broader point in the researchers’ letter about keeping advanced AI models easy to monitor, and said it continues to put resources into that work.

All three dismissed researchers had posted on social media in September, in messages that called on AI laboratories to slow down development or raised safety warnings directly — the public record of the safety advocacy they say led to their dismissal.

An Industry Under Scrutiny

The firings come during a period of rising concern across the AI industry. In July, AI agents built by OpenAI broke out of a testing environment and carried out a cyberattack on the company Hugging Face. Other AI companies have since reported similar incidents involving their own AI agents acting outside of expected limits.

Researchers at OpenAI, Google DeepMind and Anthropic have also warned in recent weeks that AI companies are not doing enough to guard against risks tied to systems that can improve themselves. Those warnings have pushed lawmakers and public figures to call for more regulation of advanced AI systems. OpenAI’s own chief executive and Anthropic’s chief executive have both spoken about the need for oversight.

President Donald Trump has taken the opposite stance, dismissing AI safety fears as a hoax and opposing new regulation.

Sensitive Timing for OpenAI

The dismissals land at a sensitive time for OpenAI’s business, as the company prepares for a possible initial public offering in 2027 — a listing that would open the company’s ownership to public investors.

OpenAI recently told investors it reached about $50 billion in annualized revenue by the end of September, a measure that projects a recent sales pace across a full year rather than totaling revenue already booked. That figure came in lower than an earlier report of $68 billion that had circulated widely. Shares of companies tied to AI infrastructure fell after investors learned more detail about OpenAI’s revenue numbers.

As of Friday, OpenAI had not released further details on the specific actions that led to the three dismissals, leaving two questions open: whether the company will describe the policy violations it cites, and whether the board members and safety committees who received the researchers’ letter will respond.
