From volume parameters to volume delivery, OpenAI, Anthropic, and Google are all competing in FDE, indicating that a true moat is a combination of engineering and business capabilities.

This article introduces the key role of FDE (Field Deployment Engineer) in AI implementation, responsible for on-site customer deployment, integration, and debugging, as well as understanding business needs. The industry focus is shifting from model competitions to commercial deployment: OpenAI has established an independent deployment company, Anthropic is collaborating with Wall Street, and Google is expanding hiring. FDEs are between engineers and consultants, needing to write code, troubleshoot, and understand business, providing enterprise-level project opportunities for graduates and helping senior engineers stay close to needs, driving AI value realization.
