    How Gemini API text pricing works

    Google lists separate standard rates for input and output tokens in the Gemini Developer API. Enter the average tokens in one request and total request volume to estimate the model-token charge.

    Prices in this review were checked on October 17, 2026. Gemini 4 Argon and Gemini 3.8 Flash have published future price changes. The calculator displays the current rate and applies each new rate automatically from its stated effective date.

    Gemini 2.0 Flash is excluded after its June 1, 2026 shutdown. Gemini 1.0 and 1.5 rates and current lifecycle status were not verified in the reviewed pricing pages, so those models are not presented as current choices.
