Use retrieval-augmented generation (vector DB) so summaries include source IDs; chunk docs and store provenance metadata; use deterministic system prompts and disable chain-of-thought; enforce redaction, RBAC, logging, and human-in-the-loop review; pilot on a subset and measure citation accuracy, coverage, and hallucination rate. Start with ChatGPT; consider Claude for very long-context/analytical tasks.
