The news: The departure of three more top executives at OpenAI indicates the generative AI (genAI) pioneer is getting closer to completing its transition from a nonprofit AI research project to a multibillion-dollar for-profit business reshaped around CEO Sam Altman. 

• CTO Mira Murati, chief research officer Bob McGrew, and research VP Barret Zoph left the startup this week, triggering a reorganization of the company’s leadership structure. 
• The latest executive exits leave OpenAI without the core leadership team that grew the plucky startup into a genAI leader of an industrywide shift.
