Evaluation-Layer Portability
RAG tooling vendors differentiate on retrieval quality, pricing, and parsing fidelity, but agencies that treat any single provider as permanent risk locking in accuracy ceilings and cost structures. Evaluation-Layer Portability is the discipline of building an internal benchmark suite that scores retrieval output against client-specific ground truth, then abstracting the RAG vendor behind that evaluation layer. When a vendor's accuracy or price degrades, the agency can swap providers without rewriting prompt logic or retraining staff. For example, an agency serving legal clients might test each vendor's ability to retrieve the correct clause from a 500-page contract; the vendor that wins this quarter may lose next quarter as open-weight models improve. This framework turns a commodity API into a defensible delivery advantage, because the evaluation layer, not the vendor, becomes the moat.
