Why agents need a separate calculator

An agent task can trigger many model calls. The core estimate istasks * calls per task * retry multiplier * token cost.

  • Repeated context can dominate input cost if it is sent on every step.
  • Retries and tool outputs make costs grow faster than simple chat usage.
  • Cost per completed task is usually more useful than cost per prompt.
Loops

Model every hidden call

Planning, tool use, critique, and final response steps can each trigger model calls.

Retries

Add failure overhead

Retries, validation failures, and tool errors can increase spend above clean-path estimates.

Unit economics

Track cost per task

Use task-level cost before pricing agent workflows or setting usage limits.

FAQ

Why are AI agents more expensive than simple chat?

Agents often make multiple model calls per task, pass repeated context at each step, process tool output, and retry failed steps. That multiplies token usage.

What is the best unit for agent cost?

Cost per completed task is usually more useful than cost per request because one user-visible task can contain many hidden model calls.
