Show HN: AI Circuit Breaker – Reverse proxy to stop agent infinite loops (circuit-breaker-sage.vercel.app)

A new tool called AI Circuit Breaker has been introduced to help AI developers manage runaway agents that can trigger infinite loops and drain API budgets. This reverse proxy detects such loops in real-time and interrupts them before significant costs accumulate, enforcing configurable spending caps without retaining any payload data. It operates with a remarkable overhead of under 35ms, making it an efficient solution for safeguarding API expenditures. The significance of AI Circuit Breaker lies in its potential to mitigate unexpected costs due to unbounded agent behavior, a concern increasingly prevalent with autonomous agents. By employing a smart loop detection mechanism, it can halt repeated requests—saving developers from financial exposure in scenarios where an agent might otherwise repetitively execute a failed command, potentially costing hundreds of dollars. Built by engineer Roan de Jager, the system offers a structured approach to budget management through rolling spend ceilings and real-time request evaluation, aiming to enhance cost control in AI/ML applications while maintaining high performance.
