Frequently asked questions

Gemini 1.5 Pro and o1-pro don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only o1-pro has a verified first-party API price: $150.00 per million input tokens and $600.00 per million output tokens. No pay-as-you-go API rate is tracked for Gemini 1.5 Pro. Gemini 1.5 Pro shipped 398 days before o1-pro, so benchmark comparisons should account for the intervening progress.

Context windows are 1M (Gemini 1.5 Pro) vs 200k (o1-pro).
