How to read it: Vapi and Retell are unbundled — the headline rate ($0.05 Vapi hosting, $0.055 Retell infra) excludes the LLM, speech-to-text, voice and telephony you add on top. Bland is bundled — $0.14/min (Start) or $0.12/min + $299/month (Build) already includes LLM, STT and TTS; only telephony is extra. Minutes = calls × (talk + transfer). Vapi and Retell bill transfer time as ordinary minutes here; Bland bills it at its transfer rate. Vapi defaults are the midpoints of its own example ranges; Retell defaults to its $0.11/min page example. Packages, concurrency add-ons and Enterprise deals are not modeled — use each platform's calculator for those.

Estimates only. Official list prices as of 2026-11-01 (Asia/Shanghai); the provider's pricing page prevails. Sources: Vapi pricing · Retell AI pricing · Bland AI pricing
