Cartesia · FinOps Profile

Cartesia Ai Finops

FinOps view of Cartesia spend. Cartesia bills a monthly subscription per tier (Free/Pro/Startup/Scale/Enterprise) that includes a pooled monthly credit allowance consumed by TTS and STT generation, plus a separate prepaid Voice Agents balance metered per minute for calls and telephony and a one-time credit charge for professional voice cloning. Concurrency ceilings rather than per-request rate limits are the operative capacity constraint, so cost and throughput scale together per plan.
