How do you design a centralized LLM control plane for enterprise-scale systems?

A centralized LLM control plane manages models, prompts, policies, routing rules, and observability across all LLM services in an organization.

A control plane in LLMOps acts as the brain of the system. It governs which models are used, how prompts are versioned, how requests are routed, and how policies like safety and compliance are enforced. It separates control logic (decisions) from data plane (inference execution). This separation enables consistent governance across multiple teams and services.
