Towards Efficient and Reliable LLM Service: A Real-World Case Study

Zhuohan Li (UC Berkeley), Lianmin Zheng (UC Berkeley)

Abstract

We present a real-world case study of deploying LLM services at scale, covering reliability challenges, latency optimization, and cost management. We identify key engineering lessons for production LLM deployments.

How this paper contributes to solving the Zone III problem (PASF-PADE)

Real-world deployment experience is the most valuable input for Zone III planning. This case study documents the engineering challenges that only emerge at production scale — essential reading for enterprise architects.

Why AI is not sufficient for Zone III without this

Zone III refers to high-complexity, high-risk, long-running agentic workflows — the class of enterprise AI deployments where a single failure can cascade across hundreds of steps. Standard AI models, trained to predict the next token, are not inherently designed for durable, governed, multi-step execution. This paper addresses one or more of the structural gaps that make Zone III deployments unsafe without explicit architectural intervention.
