AI/Agentic/LLM applications are not like microservices. When they fail, they fail like microservices plus content. In the absence of a control plane, you can’t answer basic production questions such as Which prompt version caused the issue? Which tool call leaked the data? Why did costs triple overnight? An AI Control Plane gives you standardized evaluation, tracing, drift monitoring, POO controls, rate limits, and FinOps to scale LLM apps safely.
