FAQ
Short answers about pricing, trials, and what this calculator does — and does not — do.
What is the Hume Audio Decision API price?
$0.47 per 1M input tokens, per Hume’s billing documentation (checked Nov 3, 2026).
Are model answers billed?
No. Hume documents that answers are not billed; input tokens are.
Is the Estimate API billed?
No. The Estimate endpoint is not billed. This website still does not call it.
What is the trial?
1M input tokens once the org is granted access (Hume docs).
Why don’t results match Hume’s table exactly?
Official examples are rounded; our client model is approximate (±10%). Use the Estimate API for exact figures.
Can I upload audio or paste an API key here?
No. This is a pure front-end estimator with no upload and no keys.
Do you show AssemblyAI or Deepgram prices?
Not as verified numbers. The compare page links out and labels competitor prices “Not checked.”
Who runs this site?
An independent experiment page. Not affiliated with Hume AI.
