Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it.
$0.10$2.00
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.
$0.40$6.00
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 2.5 Flash-Lite and Grok 4.7 don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Gemini 2.5 Flash-Lite is cheaper on both input and output: $0.10 vs $2.00 per million input tokens, and $0.40 vs $6.00 per million output tokens. Figures are base-tier rates. Gemini 2.5 Flash-Lite shipped 461 days before Grok 4.7, so benchmark comparisons should account for the intervening progress.

Published specifications for these two models are limited — see each model page for the latest details.
