Questions to answer before choosing

Which records require the Pro mode?
How does cache-hit behavior affect the effective input rate?
What retry rate appears at the intended concurrency?

Workload caveat

What this estimate leaves out

Displayed totals use each model's verified default profile; provider batch discounts are not automatically applied.

Latency, reliability, output quality, retries, regional processing, and provider-specific tool charges can change the practical decision.
