List-price math only. Whether the cheaper one holds quality on your workload is the question ReasonRank answers with a statistical gate + production verification.
Price answers “which is cheaper” — not “which is good enough for my workload.” ReasonRank runs both models on your own test cases, applies a statistical non-inferiority gate, and verifies realized savings on your live traffic. Run this comparison on your real workload.
