OpenAI said on Friday that it fired three safety researchers for a “breach of trust," defending the dismissals after the trio accused the company of putting its corporate interests before safety as the reason for removing them.

The ChatGPT maker said in a post on X that it “parted ways” with the researchers after an investigation found “they violated clear policies on handling sensitive information.”

The statement comes after the three researchers, Tomek Korbak, Jasmine Wang and Mikita Balesni, posted a letter to OpenAI’s various safety oversight groups detailing the circumstances around their firings and their concerns about AI.
