Barret Zoph, the head of enterprise AI sales at OpenAI, has left the company after a brief stint. Zoph rejoined OpenAI in January after a stint as co-founder of Thinking Machines Lab, where he was accused of misconduct. His departure comes just months after OpenAI vowed to focus on enterprise and coding ahead of its planned IPO. Zoph’s exit raises questions about OpenAI’s leadership and its ability to attract and retain top talent. Why it matters: This departure highlights the challenges OpenAI faces in building a cohesive team and maintaining a positive work culture, particularly given its recent struggles with internal conflicts and misconduct allegations.
