FAQ
How accurate is this Gemini 2.5 Pro token count?
Exact when a server API key is configured — counts come from Google's own count-tokens endpoint. Otherwise a clearly-labeled local estimate is shown.
Does my prompt leave the browser?
Only to Google's count-tokens API (which doesn't run the model or store your prompt) — nothing is logged by this site.
What does a Gemini 2.5 Pro request cost?
Input tokens × $1.25/1M plus output tokens × $10/1M (standard tier, as of 2026-07-07). The calculator above does this for your actual prompt.
