Three safety researchers fired by OpenAI last week—Jasmine Wang, Tomek Korbak, and Mikita Balesni—have published an open letter denying the company's accusations that they mishandled sensitive information. In their letter, they warned that the dismissals are having a "chilling effect" on OpenAI's AI safety culture, making employees afraid to openly raise safety concerns or collaborate with external experts. The researchers stated that such practices, once an integral part of OpenAI's work, could now lead to termination.
