OpenAI's head of safety systems, Johannes Heidecke, has announced his resignation as the company undergoes a significant restructuring. The restructuring aims to integrate OpenAI's safety department with its research department. According to an internal memo, Chief Research Officer Mark Chen stated that the safety team will now report to Mia Glaese, Vice President of Research and Integration Lead, who will also take on the role of Vice President of both Research and Safety. In the interim, Saachi Jain, the former head of the safety team, will step in as the head of safety systems, reporting directly to Glaese. This move is part of OpenAI's efforts to streamline operations and enhance collaboration between its safety and research divisions.
