Sources say Johannes Heidecke, head of OpenAI's security systems, informed his
team this week he will leave amid a company reorganization to merge the safety
and research divisions. An internal memo from Chief Research Officer Mark Chen
says the safety team will report to Mia Glaese, vice president for research and
integration, who will serve as vice president for research and safety; former
security lead Saachi Jain will be acting head of security systems and report to
Glaese.
