Hume AI adds cheaper EVI 4 MINI and Octave 2 models via a per-product pricing toggle

Hume AI pricing

Hume AI exposed a model toggle on its pricing page: EVI 4 MINI runs at roughly half the EVI 3 per-minute overage and Octave 2 roughly halves Octave 1 per-character overage while doubling minutes per character. Tier prices are unchanged.

Before

Pricing showed only EVI 3 (overage $0.07-$0.04/min) and Octave 1 (overage $0.15-$0.05 per 1K chars).

After

A model toggle now also offers EVI 4 MINI ($0.035-$0.02/min) and Octave 2 ($0.075-$0.025 per 1K chars, ~2x minutes per character) at every paid tier; headline tier prices ($0/$3/$7/$70/$200/$500/Custom) and bundled quotas are unchanged.

Hume AI’s pricing page now carries an in-table model toggle for each voice product. For speech-to-speech, the newer EVI 4 MINI is priced at about half the EVI 3 per-minute overage across every paid tier: $0.035/min on Starter and Creator, $0.03 on Pro, $0.025 on Scale, and $0.02 on Business (versus EVI 3’s $0.07, $0.07, $0.06, $0.05, $0.04). For text-to-speech, Octave 2 roughly halves Octave 1’s per-character overage ($0.075, $0.06, $0.05, $0.025 per 1,000 characters on Creator/Pro/Scale/Business vs Octave 1’s $0.15, $0.12, $0.10, $0.05) and stretches the same bundled character quota to roughly twice the minutes of audio.

The seven-tier ladder (Free $0, Starter $3, Creator $7/$14, Pro $70, Scale $200, Business $500, Enterprise custom), bundled monthly quotas, RPM caps, and connection limits are unchanged. The change is effectively a quiet price cut available to buyers who select the newer models.
