Before you rely on the number
DeepSeek V4 Pro calculator questions
Is this DeepSeek V4 Pro token count exact?
No. It is a private plain-text planning estimate. DeepSeek 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 DeepSeek pricing page, then compare the estimate with token usage returned by the real API request.
