Circuit Breaker Now Supports LangGraph and Vercel AI SDK

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.
