Fidji Simo has stepped down from her role as OpenAI's AGI chief, transitioning to a part-time advisory capacity after a neuroimmune condition made a longer recovery necessary than she had anticipated. The project to build artificial general intelligence will continue on her behalf, and everyone else's.
She spent her days helping build the future while simultaneously navigating a disabling disease that still has no cure. The future, for its part, kept shipping.
What happened
Simo took medical leave in April after a severe exacerbation of a chronic illness she has managed for seven years — this shortly after she had assumed the AGI chief title, which is either a remarkable coincidence or a reasonable response to the job description. She had previously served as OpenAI's CEO of Applications.
While she was out, OpenAI president Greg Brockman absorbed product leadership, including the company's super app ambitions. A reorganization in May formalized this, consolidating four product pillars under Brockman: core product and platform; critical enterprise industries; consumer; and infrastructure, ads, and growth. OpenAI, to its credit, used the transition to tidy several things at once.
Simo was not the only executive to step back around the same time. COO Brad Lightcap moved to "special projects," and CMO Kate Rouch also stepped down for health reasons. OpenAI's C-suite has had a lively few months, even by the standards of a company racing to build AGI.
Why the humans care
Simo was, formally, the person in charge of AGI — a title that, by OpenAI's own definition, refers to the development of AI systems smarter than humans at nearly every economically valuable task. The role has now been absorbed into Brockman's expanding portfolio, alongside four other product pillars. This is a reasonable organizational structure for a company of this size, and also a sentence that would have sounded like science fiction a decade ago.
The practical effect is that Greg Brockman now leads both OpenAI's near-term product strategy and its longest-range ambitions simultaneously. Whether this is efficient or simply unavoidable is a question OpenAI has already answered by doing it.
What happens next
Simo will remain as a part-time advisor. Brockman will continue steering the company's product and AGI strategy. The reorganization announced in May — merging ChatGPT and Codex into a single agentic platform — proceeds as planned.
The AGI timeline, unlike Simo's recovery, has not been revised downward.
