Full story

Fidji Simo, who led OpenAI’s advanced AI research efforts as the company’s AGI chief, is transitioning to a part-time advisory role. The move comes after she took a medical leave in April due to a neuroimmune condition. Simo had previously served as OpenAI’s CEO of applications before assuming the AGI leadership position.

Her departure follows a series of high-profile exits at OpenAI, including COO Brad Lightcap and CMO Kate Rouch, both of whom also stepped down to focus on health-related matters. Simo’s shift to an advisory role signals a broader shift in OpenAI’s leadership structure, though the company has not yet announced a permanent replacement for her position.

The timing of Simo’s exit raises questions about OpenAI’s stability in its AGI leadership, especially as the company continues to push toward advanced AI development. While OpenAI has not provided further details on her condition, the move underscores the personal and operational challenges facing the company’s executive team.
