At scale, the cheaper option saves roughly 71% if your workload shape stays similar.
Cost estimates are generated from published input and output token rates for each provider. We apply identical token scenarios to both models so the result reflects pricing differences first, then layer on context and product-positioning signals to make the page more decision-ready. This page should help you narrow the choice quickly, but final selection should still be validated against your own prompts, quality bar, and latency requirements.
