Control Plane and Workload Plane Separation for Model Serving

Baseten's model serving infrastructure is built on a control plane and workload plane architecture. The control plane manages model deployment, image building, and global load balancing across multiple Kubernetes clusters (workload planes). Workload planes are responsible for actual model inference on GPUs. This separation allows for multi-cloud, multi-region deployments, regional preference, data residency compliance, and self-hosted inference while centralizing management and reducing operational overhead.
