Price is one input to model selection

This table compares billing rates, not model quality, latency or reliability. Test a representative sample and count accepted results, retries and review time before choosing a model.

Match the workload

A short prompt and a long answer have a different cost mix from a large document and a short extraction. Use your actual input/output ratio.

Calculate your workload

Match the billing mode

Batch, cache writes, context tiers and tool fees can change the comparison. Do not compare a standard rate with a discounted rate as though they are equivalent.

Check billing assumptions
