FOCUS Specification

The formal FinOps Open Cost and Usage Specification used to standardise technology cost and usage data across providers.

Why it matters

The FOCUS Specification matters because AI cost governance depends on better-structured usage and billing data than many native provider exports currently provide.

As AI workloads spread across clouds and model providers, common data structures become more important for forecasting and reporting. For the operating context, see FinOps & AI.
