Retrieval and caching solve different problems. DeepSearcher investigates a document collection; GPTCache reuses responses where an exact or semantic match is acceptable. An orchestration framework can connect these components, but it does not establish answer quality on its own.
What to compare
- For retrieval, inspect whether the answer cites the right source passage.
- For caching, test similar requests that must produce different answers.
- Decide how source updates, user isolation and expiry affect correctness.
This is a focused selection, not an exhaustive ranking. See each profile for evidence and review scope.
