Why Cost per Verified Completion Beats Token Price
Token prices do not capture retries, failed answers, verification, tools, or the human work required to repair a result.
A low token price can still produce an expensive business outcome. If a model fails, requires multiple retries, omits a required field, or sends a person back into the workflow to repair the answer, the listed token price was not the actual cost.
Cost per verified completion measures the total execution expense required to produce an output that satisfies defined acceptance criteria.
Include the full execution path
A useful calculation includes model input and output, reasoning, tools, searches, GPU time, verification, repair attempts, and any measurable manual review required by the workflow.
- Count failed and cancelled work honestly
- Keep supplier cost separate from customer price
- Version the pricing basis and evaluation rules
- Report completion rate beside cost
- Compare identical tasks under identical acceptance criteria
A better operating metric
For teams selecting AI infrastructure, evaluate an approved execution path using evidence across quality, latency, privacy, and total cost rather than advertised token price alone.
