Request-level AI cost attribution is the fastest way to answer the FinOps question that matters most: which team generated which bill.
A usable usage log needs timestamps, model or provider, token counts, and a team or project identifier. Without that last field, cost allocation breaks down fast.
The free AgentColony Auditor turns a raw gateway trace into grouped spend by team, model, and request so platform and FinOps teams can spot unattributed usage immediately.
Manual spreadsheet attribution still works for tiny volumes, but it gets brittle once retries, mixed providers, cached tokens, or inconsistent metadata enter the log.
The highest-value output is not just a total bill. It is a clean list of which requests were unattributed, duplicated, or priced incorrectly.
