Usage & cost ledger for AI infrastructure

Reconcile every model call the way finance reconciles every dollar.

Nimbatrix meters token spend, latency and error rate across every provider you call, and attributes each line to the team, feature or customer that caused it — before the invoice arrives, not after.

The problem with a bill

Your invoice tells you what you spent. It never tells you why.

Provider dashboards report totals. Observability tools report requests. Neither one can answer "which feature is burning the budget" — that reconciliation has to happen at the call level, tagged before the request ever leaves your stack.

Attribution

Every call inherits an owner.

Tag a route once with a team, feature or customer ID. Nimbatrix carries that tag through every downstream chart, so a cost spike is never a mystery for more than one query.

Drift detection

Catch a slowdown while it's still small.

Nimbatrix baselines latency per route and alerts on drift, not just on hard thresholds — so a provider's quiet regression gets caught before it becomes a support ticket.

One schema

Every provider, one ledger format.

OpenAI, Anthropic, self-hosted models and your own internal APIs all land in the same normalized schema — so a chart comparing them is an actual comparison, not a guess.
