Free limits
Numeric limits are not recorded in structured form for this provider.
In the provider's words
Rate set by subscription tier, numbers not published; max 5,000 characters per utterance and 5 generations per request
The catch
Free and Starter tiers are non-commercial only (commercial use starts on Creator). The Free plan cannot buy overage, so going past it means upgrading. Not OpenAI-compatible. The former plan quota (10,000 characters/month) is no longer on a live official page: hume.ai/pricing redirected to the homepage on 2026-10-08.
Free models: not listed yet.
Get started
This is a first-party API, not OpenAI-compatible, so there is no drop-in base URL. The endpoint, the key and a working example are in the official docs.
