Fired OpenAI Safety Researchers Break Silence in Open Letter

Three fired OpenAI safety researchers — Jasmine Wang, Mikita Balesni and Tomek Korbak — have posted an open letter disputing their dismissals, warning that the "very public manner" of the company's communications around the firings could have a "chilling" effect on employees at a moment when, in their words, "the world's safety depends on them."

The letter, published jointly by the three dismissed employees, escalates a dispute that began last week when OpenAI terminated three staff members it alleged had shared information with an external AI safety organization. The company said in a statement that the employees "violat[ed] our policies on accessing and handling sensitive company information... breaking the trust essential to our work."

The dismissals landed at a sensitive moment for OpenAI. They followed what the letter's context describes as recent serious and potentially illegal OpenAI agent hacks of Hugging Face and other organizations, and the firing of safety employees raised awkward questions that caught the attention of lawmakers.

What do the researchers actually say?

The core of the letter is a claim about culture. The three authors argue that OpenAI's handling of their firing has changed what employees believe they can safely do.

"We have become concerned that internal and external communications around our firing have made our former colleagues afraid to speak and operate in ways that, until last week, were an integral part of working at OpenAI," the joint letter states. "We could raise safety concerns and disagree openly [before], and were encouraged to draw on the expertise of independent safety organizations. This is part of what made OpenAI special, and why we are immensely proud to have been part of the team."

The researchers stated that they "acted in line with OpenAI's mission and within the working norms of the time," and that the firing "leaves us worried that the norms inside OpenAI are shifting and that employees are now unclear on where they stand."

That last sentence carries the letter's weight. If employees cannot tell which working norms still apply, the mechanism by which safety concerns surface inside the company is weakened — and the stakes are high precisely because OpenAI builds frontier AI models.

What about the alleged leak?

The letter also addresses rumors head-on. Wang, Balesni and Korbak said they were not the leak source for a The Information article involving OpenAI's new, less monitorable architectures. They said they do not believe they engaged with external parties outside their mandate.

They added detail on process. Communication with external parties, they wrote, was done "in coordination and discussion with board members and the C-suite." Wang also disclosed that she notified an executive when she accidentally clicked on a sensitive email — an acknowledgment that a minor incident was escalated, not concealed.

The architecture angle matters on its own. "Less monitorable" architectures are model designs that make it harder to inspect or control what a system does, and the The Information article at the center of the rumor suggests OpenAI has such systems in development. A dispute over who leaked that reporting now intersects with the question of whether OpenAI's future models will remain auditable at all.

What do they want OpenAI to do?

The former employees closed the letter with concrete recommendations:

• Honor existing commitments. They said OpenAI should adhere to its public commitments to embed third-party safety auditors and not use their firing as a "pretext for stepping away from those partnerships."
• Preserve monitorability. They said OpenAI must preserve the monitorability of frontier models — the ability to inspect how the most advanced systems behave.
• Protect internal dialogue. They called on the company to maintain an "open and transparent culture of dialogue between its safety researchers and the rest of the safety ecosystem."

Each recommendation maps directly onto a live tension. External auditing commitments, model monitorability and researcher dialogue are the three channels through which outside scrutiny reaches frontier AI development. The letter implicitly argues that all three are now at risk.

What has OpenAI's response been?

In a thread on X, Jasmine Wang wrote that OpenAI leadership "is saying that they strongly agree with our letter." She paired that with a sharper assessment of the company's openness.

"We were not the first to be pushed out of OpenAI under suspicious circumstances," she wrote. "Unless employees take a stand now against this kind of maneuver, I am concerned we will not be the last. The message to everyone still at OpenAI is clear: raise concerns or work closely with outside safety groups, and you could be next, without being told why."

The company's public statement stands as its formal position: the employees violated policies on accessing and handling sensitive company information. The gap between that framing — a policy violation — and the researchers' framing — work done "within the working norms of the time" — is the unresolved core of the dispute.

Why does this matter beyond one company?

OpenAI is the developer of frontier AI models, and its internal safety culture has been a recurring subject of public scrutiny. This incident follows the firings by days, involves alleged contact with an external safety organization, and has already drawn lawmaker attention in the context of reported OpenAI agent hacks targeting Hugging Face and other organizations.

The letter's signatories frame the stakes explicitly: they say the world's safety depends on OpenAI employees feeling able to speak. If the outcome of this dispute is that safety researchers curtail contact with outside experts, the effect would reach beyond OpenAI's payroll to the broader ecosystem of independent AI safety organizations that rely on inside cooperation.

Wang's warning on X points to the next flashpoint. Whether more employees follow her call to "take a stand now," and whether OpenAI renews its third-party auditor commitments in practice, will show whether the norms the letter describes as shifting can be restored.
