Cloud Bills Took a Decade to Get FinOps. AI Bills Won't Get That Long.

Short summary

AI spend is compressing the FinOps arc from a decade into quarters. Databricks shipped cost controls alongside its Genie meter, proving vendors learned that metering without governance creates churn. The article provides concrete Python code to compute cost per query, cost per agent run, and cost per answered question — the three unit economics numbers a CFO will demand. A worked example shows how a 2.5-cent per-query cost compounds to $67K/month for 800 users once agent loops and failure rates are included.

• •AI spend follows the same adoption-invoice-governance arc as cloud, but compressed into quarters not years
• •Three key unit economics metrics: cost per query, cost per agent run, cost per answered question
• •Worked example: 800 users at $0.0255/query compounds to $67K/month after agent loops and failure tax
