July 9 (Reuters) – OpenAI’s CEO of AGI deployment ​Fidji Simo said on ‌Thursday she will step down from her full-time role and transition to a part-time advisory position at the ChatGPT maker ‌after ​an extended medical ⁠leave.

“Three months ago, I ⁠had to go on medical leave after a severe exacerbation of a chronic illness I’ve lived ​with for seven years. During that time, it became clear ⁠that the road to ⁠recovery would be much ​longer and more complex than I had ​anticipated—and that I needed to ‌focus on it fully,” Simo said in a post on X.

Simo was among the three directors that ⁠joined OpenAI’s board in March 2024 after Sam Altman returned as CEO.

“I am really ⁠sad ‌about this and very ⁠grateful for all Fidji has ​done ‌for OpenAI, and even ​grateful for ⁠her friendship and who she is as a person,” Altman said in an X post.
