The Hidden Cost of Agentic AI

Where the dollars actually go.

What this chapter covers

The sticker price of an AI model is not the real cost of running an agent. Retrieval, embeddings, evaluation, memory, orchestration, and human review all add up quietly. This chapter opens the bill and shows where the money actually goes.

Why token costs are usually the smallest line item
How poor context design multiplies inference cost by 10x
Where evaluation and observability spend hides
A back-of-envelope cost model for a typical enterprise agent

Why it matters

You cannot manage what you cannot see. Once you can read the bill, cost design becomes a solvable problem.
