What’s the worst "bill shock" spike you’ve hit running AI in production?

Summary

This post asks engineers to share their experiences with unexpected cost spikes when running AI models in production and offers advice on optimizing costs and setting up guardrails to avoid budget overruns.

Hey everyone, We are looking at scaling up our LLM usage, and frankly, the potential for a surprise API bill is keeping me up at night. It feels like one bad recursive loop or an unoptimized prompt can tank a budget instantly. I want to hear your engineering scars—not the textbook solutions. If you've spent weeks debugging a massive OpenAI or Anthropic bill, what did you learn the hard way? Specifically, I'm curious about: The Spike: What actually broke to cause your last massive cost spike? The Fix: What actually worked to cut costs (caching, routing, smaller models)? The Stack: Did you have to build internal tracking tools, or is everyone just using manual spreadsheets? The Blame: Who actually gets yelled at when the API bill arrives? Any advice for someone trying to set up guardrails before things get out of hand? What’s the biggest lesson you learned the hard way?
