Local models, because finance data does not leave the building
The choice
Two self-hosted models: one writes the query, a separate one explains the result. No question, no schema and no row of data goes to an external service.
Why
“Our numbers cannot go outside” is the most common and most reasonable reason a finance team refuses AI. Self-hosting removes the question entirely — and removes per-query cost, which starts to matter the moment a team gets into the habit of asking.
What it means for you
Your data-protection answer is “it never left our server”, not “the vendor says it is fine”.
