These turn per-token and per-character provider prices into a cost per minute of live conversation. Defaults reflect a typical back-and-forth call. Edit them to match your agent.

Model prices from pricetoken.ai, refreshed on each deploy. Telephony and LiveKit are transport costs, not AI models, so they show blended estimates (details on the ? next to each).

Self-hosting keeps more than Vapi, per month --

Managed platforms bill your users for you and stack a per-minute fee on top of the same providers. Self-hosting on LiveKit means you bill your own users and keep the spread. Rates are typical all-in estimates. Edit them to match a real quote.

ShipVoice wires this metering into Stripe so your users are billed automatically, with your margin baked in.
