On 2 October a spokesperson told the BBC that OpenAI's investigation had confirmed the three had mishandled sensitive information outside established company procedures. Then the former employees published an open letter to OpenAI leadership, and Balesni wrote on X: "I believe we were fired for prioritising safety over the near-term interests of OpenAI as a corporation."

OpenAI replied on Friday 9 October with a note from research leaders: "We want to be very clear that these decisions were not about raising safety concerns or speaking out." It added that its internal investigation found "a significant breach of trust beyond what's outlined in the letter they published" and that it stands by the decision to end their employment.

The letter says the firings left remaining staff "afraid to speak and operate in ways that, until last week, were an integral part of working at OpenAI". Wang wrote that they were "not the first to be pushed out of OpenAI under suspicious circumstances" and warned that unless employees take a stand "we will not be the last".

The technical issue behind Korbak's claim is the monitoring of agent reasoning. Labs and researchers use the visible reasoning of a model as one signal for catching when an agent is doing something it should not. If that signal becomes unreliable, one of the main tools for catching misbehaviour weakens. The BBC quotes Korbak calling it "one of our best tools for catching when they misbehave". OpenAI has not said, in the quoted material, whether it disputes that concern.

OpenAI also said it is finalising contracts with third-party safety assessors and will announce details in the coming weeks. The timing matches a wider public debate on independent audits; the same week Microsoft's president called for outside evaluators to sign off on AI products.

What we do not know: what information was shared, with whom, and why. The BBC article gives no detail on either side's evidence, and neither claim can be checked from public documents. Readers should treat both accounts as statements by interested parties.
