AI model economics hub FAQ

Questions before you start

Does this show my provider bill?

No. The calculator uses published prices, and the analyzer prefers a cost field from your own export.

Do my files leave the browser?

No. The usage analyzer parses and aggregates CSV and JSON data locally in the browser.

Can the cheapest model replace my current model?

Not by itself. Test quality, latency, reliability, safety, and policy fit on your own workload.
