OpenAI has confirmed that Barret Zoph has left the company again after a five-month stint following his return in January. The departure comes amid ongoing internal tensions and recent reports of misconduct involving Zoph.
According to OpenAI, Zoph’s departure was announced via a message he posted in the company’s Slack channels. The company confirmed to The Verge that Zoph is no longer with OpenAI, although specific reasons for his exit were not disclosed. Zoph rejoined OpenAI in mid-January after serving as co-founder and CTO of Thinking Machines Lab, a competing AI startup founded by former OpenAI CTO Mira Murati.
Shortly after his return, Zoph was appointed to lead OpenAI’s enterprise division, a key strategic focus for the company as it prepares for a potential IPO. However, reports emerged shortly afterward indicating that Zoph’s departure from Thinking Machines Lab was abrupt and linked to alleged misconduct involving an undisclosed relationship with a colleague. Murati announced in January that Thinking Machines Lab had “parted ways” with Zoph, and he was replaced as CTO.
The internal tensions between OpenAI and Thinking Machines Lab, along with recent leadership upheavals—including Murati’s brief stint as CEO during Sam Altman’s ouster—highlight a period of instability. Zoph’s return to OpenAI was publicly welcomed by Fidji Simo, OpenAI’s CEO of Applications, who stated that his return had been “in the works for several weeks.”
Implications for OpenAI’s Leadership and Strategy
Zoph’s departure so soon after returning raises questions about leadership stability at OpenAI, especially as the company refocuses on enterprise and core revenue streams ahead of its IPO. The internal tensions and misconduct allegations could impact the company’s strategic planning and internal culture, potentially influencing investor confidence and future hiring decisions.
This event underscores ongoing challenges within OpenAI’s leadership ranks, amid broader industry concerns about corporate governance and internal trust. It also highlights the fragility of talent retention at high-profile AI firms during periods of internal upheaval.

Recent Leadership Changes and Internal Tensions
In November 2023, OpenAI’s CEO Sam Altman was ousted, leading to a brief leadership void that was filled by Mira Murati, who also briefly served as CEO. During this period, Murati testified in a trial that she couldn’t fully trust Altman’s statements, reflecting internal disagreements and mistrust.
In September 2024, Murati left OpenAI to start Thinking Machines Lab, taking some former colleagues with her. Zoph was among those who left and then rejoined OpenAI in January 2026, just months before his departure. His return was seen as part of OpenAI’s effort to bolster its enterprise division, a key focus as the company prepares for a potential IPO.
However, reports of misconduct and internal conflicts have complicated this picture, leading to Zoph’s abrupt exit after only five months back at the company.
