Why enterprises should add a model routing layer instead of one LLM for all use cases

Enterprises often run multiple AI use cases—employee Q&A assistants, contract information extraction, and processing customer requests from external portals/CRMs—on one platform. The author argues these have very different requirements: one may need strong reasoning, another high volume at low cost, so a single GenAI model isn't necessarily the answer.

His proposed approach: add a Model Routing Layer that selects models per use case based on requirements, data restrictions, and cost. This also avoids lock-in to one LLM and makes swapping models easy when needed.
