Frequently asked questions

How do I estimate AI API cost?

Paste your prompt, choose a supported model, enter the expected output token count, and run the estimator to see input, output, and total cost.

Does this tool count prompt tokens automatically?

Yes. The estimator measures the prompt text first, then combines that input count with your expected output token count.

Are these AI prices live?

No. This tool uses a maintained pricing table and shows the pricing review date in the output, so you should still verify critical billing decisions against the provider's latest pricing page.

Are Gemini and DeepSeek token counts exact?

No. Gemini and DeepSeek options on this page use local token estimation, so pricing totals should be treated as useful estimates rather than exact billable numbers.

Does this estimate include cached input or tool-call fees?

No. The current estimate is for standard uncached text input and output tokens only.
