# Circuit Breaker Now Supports LangGraph and Vercel AI SDK > Source: > Published: 2026-05-26 13:11:43+00:00 Runtime governance for autonomous AI workflows is becoming framework-native. Over the last few weeks we’ve been exploring a problem that increasingly shows up once AI systems become more autonomous: runtime behavior becomes operationally unpredictable. Not because the models are “bad.” But because long-horizon agent workflows naturally introduce: recursive retries tool loops escalating context windows execution drift unstable recovery paths unpredictable runtime costs As a result, we’ve been building: Circuit Breaker An open-source runtime governance and execution budget layer for AI agents. This week we added support for: LangGraph Vercel AI SDK Why We Built This Most current AI infrastructure focuses heavily on: orchestration tracing observability prompt tooling evaluations These are important. But we kept running into a different operational problem: What happens once execution itself becomes unstable? Examples: recursive tool invocation retries that never converge workflows that technically continue executing while producing diminishing value runaway inference cost from small percentages of anomalous runs Traditional distributed systems eventually evolved: timeout controls circuit breakers bounded failure domains retry governance We believe autonomous AI systems are beginning a similar transition. What Circuit Breaker Does Circuit Breaker helps developers add runtime governance primitives to AI workflows, including: execution budgets runtime ceilings retry constraints bounded execution behavior operational safeguards for long-running agents The goal is not to limit capability. The goal is: operational predictability for probabilistic systems. Why LangGraph and Vercel AI SDK Matter Both ecosystems are increasingly being used to build: multi-step agent workflows tool-enabled systems autonomous execution graphs long-running AI applications As these systems grow in complexity, runtime behavior becomes just as important as model capability. Adding support for LangGraph and Vercel AI SDK felt like an important next step toward making runtime governance easier to integrate directly into production workflows. A Bigger Shift We’re Watching One thing that increasingly stands out to us: AI infrastructure is slowly evolving from: “How do we orchestrate intelligent systems?” toward: “How do we govern probabilistic execution systems economically and operationally?” We’ve started thinking about this broader shift as: Runtime Economics Where execution itself becomes economically significant during runtime. Not just at deployment. Not just at billing. During execution itself. Still Early — Looking for Feedback Circuit Breaker is still early and evolving quickly. We’d genuinely love feedback from: developers building agent systems LangGraph users Vercel AI SDK users infra engineers teams experimenting with long-horizon workflows GitHub: [https://github.com/MonetiseBG/circuit-breaker](https://github.com/MonetiseBG/circuit-breaker) Would love to hear how others are approaching runtime governance and bounded execution in autonomous systems.
