Summary

An enterprise leader shares an honest account of building and scaling AI enablement services within a large, regulated organization, serving tens of thousands of users. The journey began with traditional machine learning workloads, evolving into the rapid deployment of generative AI capabilities, including an internal AI assistant built on OpenAI models via Microsoft Azure. The team navigated significant challenges such as establishing credibility among dispersed teams, hardening security boundaries, and managing a "Cambrian explosion" of Retrieval-Augmented Generation (RAG) chatbots. Key developments included migrating to SageMaker for Jupyter users, adopting AWS Bedrock for advanced AI, and transitioning to self-service platforms like Simple Chat. The narrative emphasizes the critical role of infrastructure, policy, compliance, and a structured AI use-case lifecycle in achieving operational maturity.

Key takeaway

For CTOs and VPs of Engineering tasked with standing up enterprise AI, prioritize foundational infrastructure and cross-functional partnerships from day one. Your success hinges less on cutting-edge models and more on robust security, cost governance, and a structured lifecycle for AI use cases, ensuring prototypes deliver sustained value rather than languishing. Embrace necessary compliance processes and integrate them early to mitigate significant risks at scale.

Key insights

Scaling enterprise AI requires robust infrastructure, clear policy, and strong cross-functional partnerships, not just advanced models.

Principles

• Infrastructure is the iceberg; models are the tip.
• Policy, technology, and education must work together.
• Embrace bureaucracy for safety at scale.

Method

Implement a structured AI use-case lifecycle from ideation to sustainment, ensuring prototypes transition to production with planned handoffs, monitoring, and retraining cycles.

In practice

• Partner early with cloud services and IT teams.
• Budget for identity, network, and cost governance.
• Integrate with software review boards for AI tools.
