OpenAI Exec Fidji Simo Steps Down Due to Health

OpenAI's core management team is undergoing a significant change as Fidji Simo, CEO of AGI Deployment, steps down from her full-time position due to health reasons. This shift has drawn external attention to the stability of OpenAI's core business operations.

Reasons for Departure and Role Transition

According to multiple reports, Simo went on medical leave three months ago due to an acute exacerbation of a chronic neuro-immune disease. Because her recovery has been longer and more complex than expected, she decided to prioritize her health. She will no longer participate in daily leadership but will remain with the company as a part-time advisor. Previously described by media as OpenAI's "No. 2 executive," she led the company's strategic transformation and the early stages of the "super app" plan, notably resulting in the new ChatGPT application.

Business Takeover and Power Transition

Following Simo's departure, her responsibilities over the app team, user-facing product lines, and related business operations have been redistributed. Co-founder and President Greg Brockman will take over core product lines like ChatGPT and report directly to CEO Sam Altman. Additionally, relevant duties will be shared with CFO Sarah Friar and Chief Strategy Officer Jason Kwon.
