Brad Lightcap, OpenAI's chief operating officer and one of its longest-serving executives, is leaving the company after nearly a decade to 'start something new.' His departure marks the latest high-profile exit from the AI lab, though he indicated he would continue supporting the mission from outside the organization.
OpenAI announced multiple C-suite changes including AGI deployment CEO Fidji Simo taking a leave of absence, CMO Kate Rouch stepping away for cancer recovery, and COO Brad Lightcap moving to a new 'special projects' role. President Greg Brockman is stepping in to fill leadership gaps.
