OpenAI Promotes Model Training Researcher to Lead Enterprise Sales

Barret Zoph, who directed training for GPT-4 and o1, has rejoined OpenAI as head of enterprise AI sales. Zoph and co-founder Luke Metz left in September 2024 to start Thinking Machines Lab before returning. The move embeds deep technical credibility into a revenue-focused role, signaling that OpenAI sees enterprise deals growing complex enough to demand research-level expertise in customer-facing leadership.
