Full Yuma AI profile and vendor sources · Checked 2026-09-02
The table below preserves each vendor’s scope and qualifiers. An unlisted feature is unverified here; it is not a claim that the feature is unavailable.
Before you decide
Vapi: Usage-based hosting plus provider costs for transcription, language models, speech and telephony. Bring-your-own keys move provider billing to your own account. Includes 10 concurrent calls; extra lines cost $10/month each. Scale uses a quoted platform fee and committed volume under an annual contract. Yuma AI: Charges for fully automated resolutions; tickets touched by a human are excluded. The pricing page lists $1.50 per extra resolution on monthly plans, but the base monthly fee is unpublished. Custom integrations and other AI add-ons are quoted separately. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
The recorded sources for Vapi include prompts; custom functions; documents; external APIs. For Yuma AI, they include helpdesk tickets; store catalog; orders; policies; macros. Ask each vendor to demonstrate ingestion or live access for the exact system you use, with permissions and refresh behavior. A source missing from this directory is not proof that a vendor cannot support it.
Use the same sample of real support requests, approved knowledge, and escalation rules in both pilots. Can it cite or restrict answers to approved knowledge? What happens when the agent is uncertain? Which actions can it complete beyond answering? Record answer quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Vapi: Total per-minute cost includes selected STT, LLM, TTS and telephony providers; more engineering is required than turnkey tools. Yuma AI: Sales-led pricing and dependence on an existing helpdesk; confirm supported actions and languages.

| Pricing summary | Pay as you go: $0.05/minute for call hosting or $0.005/message for SMS/chat hosting (USD), plus model, speech and transport-provider charges. These are platform fees, not the full cost of a call. | Monthly base price by quote. Published bundles require a 12-month commitment and upfront annual payment. Likely a higher-budget option than entry-level self-serve tools; confirm monthly terms and total cost with sales. |

| Differentiator | Composable developer stack with provider choice and infrastructure controls. | Explicit no-charge policy for conversations/escalations and focus on ecommerce workflows. |
