description: >-
  FOCUS-aligned FinOps view of Hume AI. Hume bills via subscription plan tiers (with bundled
  TTS characters and EVI minutes) plus per-character TTS overage and per-minute EVI overage.
  Expression Measurement is fully pay-as-you-go priced per minute, image, or word.
notes: Plan-tier sizing is the dominant FinOps decision; right-size based on monthly TTS character + EVI minute projections.
