Three former OpenAI safety researchers published an open letter on Thursday saying they were abruptly dismissed last week and warning the moves will have a "chilling effect" on company culture, Business Insider reported. Mikita Balesni, an AI alignment researcher, posted the letter to OpenAI's safety committee; the two other signatories also worked on AI safety. OpenAI said an internal investigation found the three violated company policies on access to and handling of sensitive information. The researchers said they were only given verbal explanations for their dismissals, maintain their actions were within their job duties, and worry colleagues may now be "afraid to speak up" or "hesitant to undertake certain work."
