Introduction

Welcome back, future AI observability experts! In our previous chapters, we laid the groundwork for understanding AI system health through comprehensive logging, distributed tracing, and critical metrics. We learned how to see what our AI systems are doing and how well they’re performing.

Now, it’s time to tackle another crucial, and often overlooked, aspect of running AI in production: cost. The rise of powerful Large Language Models (LLMs) and sophisticated AI APIs has brought incredible capabilities, but also a new challenge: managing unpredictable, usage-based expenses. A single runaway prompt or an inefficient model interaction can quickly inflate your cloud bill, turning innovation into a financial headache.
