Each chapter answers one question
Chapter 1: Do fewer calls really mean a smaller bill?
What am I paying for in a single call?
Model costs are charged by the volume of text in and out, not by the number of calls.
Chapter 2: Does a cheap call mean a cheap job?
What does it cost me when one user completes one task?
The number to remember is the cost per task a user completes, not the cost per call.
Chapter 3: Is the biggest model always the safest choice?
Which of my tasks use a bigger model than needed?
Give simple tasks to a small model and the results are no worse while the price is many times lower.
Chapter 4: How many words are we paying for that go unused?
Am I sending the model things it does not need?
Most of the text sent to the model is never used in the answer.
Chapter 5: Why does the monthly bill always surprise us?
How long does it take me to notice an unusual cost spike?
Costs looked at weekly never become a surprise at month end.
