Vapi
Real infrastructure behind the $50M raise and the Amazon Ring deployment — but budget 3-7x the advertised $0.05/minute once STT, LLM, TTS and telephony all send separate invoices.
PRICING
| Build | $0.05/min | usage-based, no monthly fee |
| Scale | Custom | annual contract, volume pricing |
No seat pricing. Build bills $0.05/min of Vapi hosting plus $0.005/msg for SMS/chat, with model provider costs (STT, LLM, TTS) passed through at cost or $0 if you bring your own API keys. 10 concurrent lines included, then $10/line/mo. HIPAA is a $2,000/mo add-on and Zero Data Retention $1,000/mo on both plans.

Strengths
Broad bring-your-own-model support across every major LLM provider, a mature function-calling/MCP surface, and Squads for production multi-agent handoffs (240,000 calls/day at one customer). Flow Studio, Workflows, official SDKs and a CLI form a real harness, and native Evals, Simulations and Monitoring (GA April 2026) give teams in-platform testing without a third-party eval layer. Amazon Ring routing 100% of inbound support calls through Vapi after evaluating 40+ vendors is a serious production proof point, backed by a $50M Series B at a ~$500M valuation.
Honest dings
The advertised $0.05/minute is the platform fee only — independent breakdowns (CloudTalk, Retell, Zeeg, Rezora) consistently land the true all-in cost at $0.13-0.36/minute once STT, LLM, TTS and telephony are counted, and HIPAA plus Zero Data Retention add $3,000/month before any usage. Trustpilot sits at 2.4/5 with recurring billing-surprise and slow-support complaints. No native vector store or embeddings — RAG leans entirely on a third-party index (LlamaCloud).
