# Why your LLM bill exploded overnight (and how to regain control)

**[WunderGraph](https://daily.dev/sources/wundergraph)** · 13 min read · 0 upvotes · 0 comments

## Summary

LLM bills spike overnight not from steady usage but from retry storms, agent loops, prompt bloat, and RAG over-retrieval compounding with no shared control point. Provider dashboards often miss these patterns until it's too late. The recommended approach is routing all LLM traffic through a single boundary (like a federated graph router), enforcing retry budgets, token caps, circuit breakers, and cost-aware model routing centrally, and monitoring unit metrics like tokens per request, retry rate, and cost per tenant to catch spikes within minutes. A concrete incident response playbook covers the first 60 minutes: diagnose, contain, then resolve. WunderGraph's Cosmo Router is presented as the enforcement layer for these controls.
