From prompt to request cost
Estimated request cost equals input tokens multiplied by $3 per million, plus expected output multiplied by $15 per million. Cached input is separate only when the provider publishes a rate.

Before you rely on the number
Kimi K3 calculator questions
Is this Kimi K3 token count exact?
No. It is a private plain-text planning estimate. Moonshot tokenization, chat formatting, tools, files, and images can change the real count.
Does the prompt leave my browser?
No. The calculator runs locally in your browser. Only the page itself and published registry data are loaded from PromptCostLab.
How should I verify production cost?
Check the linked Moonshot pricing page, then compare the estimate with token usage returned by the real API request.
