ARBR is an open-source, self-hosted control plane for teams that already send meaningful AI traffic to production. It focuses on a specific operational problem: identifying requests that may be served by a cheaper model, proving the replacement works on representative traffic, approving the switch, and measuring whether savings held after rollout. This is more focused than a generic API gateway. ARBR links cost, latency, selected model, and outcomes to applications, teams, workflows, task types, and users, then turns the observed workload into model-switching recommendations.
