How this is calculated
We cost the same workload on both models — (input × input price + output × output price) per request, scaled by requests per month — and show the per-request and monthly difference with the exact dollar gap. Change either model to compare any two.
Is this a good result? What to do next
Gemini Flash tiers are usually the cheapest, while Claude and Gemini Pro flagships sit closer together — so the winner depends on tiers and your token mix. Always test quality on your own tasks; the cheapest model isn't always the best fit.
