OpenAI senior security and ethics leaders separated consecutively

The top security and ethics leaders of OpenAI left in just a few weeks. Chloe Bakalar, the head of ethics at OpenAI, left less than a year after joining, followed by the departure of Johannes Heidecke, the head of the security system, and Joshua Achiam, the former head of mission. These departures are taking place at a time of increasing scrutiny of artificial intelligence security, model control and human oversight。
