Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it.

Output priceWhat you pay for the text the model writes back. It is normally the dearer half: producing an answer costs more than reading one.
$12.00—
Cached input priceA reduced rate for text you send over and over. If every request starts with the same instructions or the same document, the provider keeps a copy ready and charges less to read it again.

Frequently asked questions

Gemini 3.1 Pro and o3-mini-high don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only Gemini 3.1 Pro has a verified first-party API price: $2.00 per million input tokens and $12.00 per million output tokens. No pay-as-you-go API rate is tracked for o3-mini-high. o3-mini-high shipped 384 days before Gemini 3.1 Pro, so benchmark comparisons should account for the intervening progress.

Context windows are 1M (Gemini 3.1 Pro) vs 200k (o3-mini-high).
