Measure AI cost per useful task, not only cost per token

Connect model, orchestration, retrieval, storage, review, retry, and support costs to a completed task the venture values.

Direct answer

Tokens, compute time, and API calls are billing units. A venture needs a decision unit such as cost per reviewed support draft, accepted document extraction, or completed workflow. Count retries and human review in the denominator and numerator.

Decision sequence

  1. Define the useful task and the acceptance rule that determines whether it completed.
  2. Measure every paid and internal component needed for the task, including failed attempts and review.
  3. Calculate low, expected, and peak monthly ranges rather than one precise forecast.
  4. Compare actual cost and useful completion rate after a bounded pilot.

Evidence to keep

  • A billing-unit inventory.
  • A useful-task acceptance rule.
  • Retry, rejection, and review rates.
  • An owner for budget alerts and model changes.
