What does a price spread establish?
Compare endpoint prices, accepted task quality, and total operating cost separately. A large difference in listed rates does not prove that two routes produce equivalent outcomes.

What a defensible comparison needs
Publish the assumptions alongside the result.
Specify the endpoints, price date, input/output mix, eligibility requirements, and task distribution. Test the same representative cases on both configurations. A rate ratio alone says nothing about whether the lower-priced endpoint meets the task requirements.
Measure baseline and candidate costs with the same boundary, including retries, tools, evaluation overhead and unsuccessful runs. Report cost per accepted outcome and the acceptance criteria. Separate an illustrative calculation from an observed production result.
Without the underlying observations, a percentage should not be presented as typical enterprise savings. Readers should be able to reproduce the arithmetic and understand what the evidence does not establish.
