| Free tier | The API is no longer self-serve: 'The API is currently in limited release; contact our team to request access', on the Expression Measurement overview. The pricing URL no longer exists as a page: https://www.hume.ai/pricing and https://platform.hume.ai/pricing both land on the marketing home page, which now sells a voice-AI evaluation platform rather than an API. Third-party readings of the pricing page from September 2026 recorded a Free plan at '10,000 characters per month, 5 EVI minutes, 15 requests per minute, 1 concurrent connection' plus USD 20 of new-account credits. unit minutes; metered on wall-clock; application-gated |

| Composes with | the interesting part of the September free tier was 10,000 characters of Octave TTS plus 5 EVI minutes on one email; with the gate now in place, the only route is to substitute ElevenLabs or Cartesia, both recorded at 10,000 and 20,000 monthly credits. |

| Reliability | no reliability event recorded |

| Notes | These are inference credits, not general compute. The finding is the withdrawal of a self-serve free tier behind an access request, which is why the verdict is fails-identity rather than dead: Hume sells and its evaluation product is live, but the API needs an approved conversation. Data point worth carrying: the site's own benchmark page labels one model view 'Illustrative, not real data', so the leaderboard numbers on the new home page are not measurements. |
