According to Jin10, three former OpenAI researchers said in an open letter on Thursday that they were suddenly fired last week, a move they said would have a chilling effect on the company culture. OpenAI spokesperson said an internal investigation found the three employees violated company policies on access to and handling of sensitive information. The three said the company only gave them a verbal explanation for the dismissals and that their actions did not go beyond their job duties. In the open letter, they said they feared former colleagues might now be afraid to speak up or work in certain ways.
