Fidji Simo Steps Down from OpenAI's No. 2 Role Fidji Simo has stepped down from her full time position as second in command at OpenAI, a move that marks a significant blow to the company's leadership ranks.
In a staff note Thursday, the company announced Simo would transition to a part time advisory role. Simo's departure comes after an extended medical leave that proved longer and more challenging than expected.
The timing is notable given OpenAI's plans for a possible initial public offering in the near future.
