AI cost control: How to stop runaway agent loops with circuit breakers

A technical guide outlines methods to prevent runaway AI agent loops that can unexpectedly increase API costs. The author suggests implementing per-feature circuit breakers, which monitor recent API calls for patterns like repeated identical requests or rapidly growing context windows. This approach allows for the throttling or blocking of only the misbehaving feature, unlike account-wide budget limits. The post includes a TypeScript code snippet for a DIY circuit breaker and discusses existing tools like LiteLLM, Helicone, Portkey, Langfuse, and AtlasBurn that offer similar functionalities. AI
