OpenAI's Fidji Simo Steps Down

Simo, who had been on medical leave, announced her departure to focus on her health, leaving a key gap in OpenAI's executive team.

Her exit comes at a critical juncture as the company accelerates its commercialization efforts and faces intense competition from Anthropic.

OpenAI has been restructuring its leadership and recently launched new products to drive growth.

Simo's departure may raise questions about stability as the company eyes a public listing.
