- Fidji Simo is leaving her full-time role at OpenAI and moving to a part-time adviser position after her medical condition worsened; she had been on extended medical leave for three months following a severe flare-up of a chronic illness she has lived with for seven years.
- The departure removes the head of OpenAI's AGI deployment effort, described by outlets as the company's No. 2 executive, just as the AI giant prepares to go public.
- Sam Altman called Simo's exit painful, saying he was "really sad" and grateful for everything she had done for OpenAI and as a friend, wishing her a speedy recovery.
- Amir Efrati of The Information noted the change had been the working assumption for some time, pointing to revenue chief Denise Dresser as already getting significant airtime and responsibility during the interim.
- Simo revealed Facebook once offered her a full year of medical leave after she first got sick — an offer she declined on the spot, saying she now wishes she had listened when "Zuck told me I should play the long game."
- Long-time collaborator Sriram Krishnan praised Simo as "one of the best people I've worked with" and said she plans to focus on helping others through her venture Chronicl, while MIT bioengineer Linda Griffith called her a "warrior" inspiring chronic-illness patients.
Why it matters: Losing the executive running AGI deployment right before an IPO leaves a vacuum at the No. 2 slot, and The Information's Efrati already flags revenue chief Denise Dresser as the de facto stand-in — meaning OpenAI's pre-IPO hierarchy is shifting toward commercial leadership over AGI policy in the short term.
