  Cartesia sells five tiers - Free, Pro, Startup, Scale, and Enterprise -
  each combining a monthly credit allowance (consumed by TTS/STT usage),
  a separate prepaid Voice Agents balance, and rising per-plan concurrency
  limits on TTS and STT connections and agent slots. Voice cloning and
  organizations unlock on paid tiers; priority support and custom
  concurrency arrive at Scale and Enterprise.
notes: >-
  Credit-to-dollar conversion and per-character/per-minute burn rates are
  not published on the pricing page as flat numbers; verify current credit
  costs per model/feature in the Cartesia dashboard on reconciliation.
  Concurrency and credit figures below are as published on cartesia.ai/pricing.
