Illustrative configuration, not a fixed Vapi tariff. Amounts per billable call minute.
The model allowance is our explicit example: 4,000 × $2 per million input tokens + 500 × $8 per million output tokens = $0.012/min, without caching. Longer prompts, different models, speech volume and provider plans change the result. This narrow range covers the connection options above, not every possible Vapi configuration.
One Twilio US local number adds $1.15/month. Keeping 1,000 recorded minutes adds $0.50/month at the listed storage rate: approximately $120.65 to $124.65 for this usage, one number and one month of storage, before tax. Billing rounding, transfers, optional post-call analysis and additional services can increase the bill. Bring-your-own keys change who bills you, not whether provider usage costs money.
