You deploy a four-agent pipeline that should cost about $0.80 per run. By end of day it has burned through $47 on a single stuck researcher loop. Sound familiar?
If you're running AI agents in production, cost blowups are not a question of if but when. 57% of organizations already have agents in production, yet 90% of agent projects fail within 30 days — and runaway LLM costs are the number one pain point.
The core problem: agents make autonomous decisions about how many LLM calls to issue. A retry loop, an overly verbose chain-of-thought, or a stuck tool call can silently 10x your bill before you notice.
The Current State of Agent Cost Control
Most teams handle this with one of three approaches, all of which fall short:
Manual monitoring. You watch dashboards and kill processes when costs spike. This works until you're asleep, in a meeting, or running 20 agents in parallel.
Provider-level spending caps. OpenAI and Anthropic offer monthly limits, but they're account-wide. You can't set a $5 budget for a specific research pipeline while allowing your coding agent $50.
Gateway proxies (Helicone, Portkey). These require routing all traffic through an external service. They add latency, a point of failure, and vendor lock-in. And they still don't give you per-agent circuit breakers.
What's missing is a framework-native solution: something that hooks directly into CrewAI, AutoGen, or LangGraph at the process level, enforces hard limits before each LLM call, and trips a circuit breaker when things go wrong — without requiring any external infrastructure.

If you're running agents in production and haven't had a cost blowup yet, you will. The question is whether you'll catch it at $2 or at $200.
