Woofun AI reports that OpenAI Chief Research Officer Mark Chen announced the departure of security chief Johannes Heidecke following an internal restructuring. The security team will now report directly to Vice President of Research Mia Glaese, integrating AI security, model safety, alignment research, and core R&D under a unified management framework. This organizational shift occurs as Apple Inc. pursues legal action against OpenAI, alleging organized theft of trade secrets regarding upcoming products and encouraging employees to share proprietary materials.
