FAQ
How accurate is this Grok 3 token count?
Exact when a server API key is configured — counts come from xAI's own count-tokens endpoint. Otherwise a clearly-labeled local estimate is shown.
Does my prompt leave the browser?
Only to xAI's count-tokens API (which doesn't run the model or store your prompt) — nothing is logged by this site.
What does a Grok 3 request cost?
Input tokens × $3/1M plus output tokens × $15/1M (standard tier, as of 2026-07-07). The calculator above does this for your actual prompt.
