About this course

Most teams do not fully understand how AI and cloud costs work until something goes wrong. Token billing, context windows, model tiers, and provider-specific pricing all interact in ways that make spend hard to predict. This course walks you through the cost model from first principles, shows you what drives spend in practice, and teaches you how to set up the monitoring that catches changes before they become surprises.

What you will learn

  • How token billing, context windows, and model tiers affect your monthly spend
  • Which cost signals matter day to day vs which are noise
  • How to set up production monitoring that gives you daily visibility
  • Why relying on provider dashboards alone creates blind spots
