Circuit Breaker — AI Glossary
A resilience pattern that stops sending requests to a failing service after a threshold of errors, preventing cascading failures.
Overview
Circuit breaker states: Closed (normal, requests pass through), Open (error threshold exceeded, requests fail fast without calling the API), Half-Open (test requests flow through; if they succeed, return to Closed). For LLM gateways: circuit break a provider after 5 consecutive 500 errors; route to a fallback provider while open.
