How do you design an internal LLM platform for multiple teams in an enterprise?

An internal LLM platform provides shared APIs, model routing, prompt management, evaluation pipelines, and governance for all teams in an organization.

An enterprise LLM platform abstracts complexity from individual teams and provides a unified interface for model access, prompt versioning, safety policies, and observability. It includes a control plane (policy, governance, routing) and a data plane (inference execution). It also enforces standardized evaluation, logging, and cost controls across all LLM applications.
