Four things ModelBrake does that your provider dashboard won't.
Cloud dashboards show you the damage after the invoice arrives. ModelBrake catches it in minutes and can stop it.
Real-time cost polling
We poll the OpenAI, Anthropic, and Bedrock usage APIs every 60 seconds. You see cumulative spend per key, per model, per project — before the invoice.
Anomaly detection that isn't a fixed alert
Statistical baselines per key. A key spending 10× its trailing hourly average triggers immediately — even if it's still under your daily budget.
Hard-stop circuit breakers
Not just alerts. Set a spend ceiling and ModelBrake revokes the API key when it's breached. The runaway loop stops. You unrevoke when you're ready.
Per-customer attribution
Tag requests with a customer ID header and see spend by tenant. Know which customer to bill, which to throttle, which to churn.
