Movement

This is the first edition on this tier, so no move can be computed for Vapi yet. From the next edition this section shows, per buyer segment and per category, whether its share moved by more than the measured noise floor.

By model

How each model treated Vapi across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“*Developer-first / Infrastructure:* Vapi, Retell AI, Vocode, or Bland.ai. (Excellent for high customization, low latency, and BYO keys).” Gemini 3.5 Flash · AI voice agents · scale prompt · first choice

“Choose Vapi if you want the fastest path to a production phone agent or a configurable voice-agent stack across many providers.” GPT-5.4 mini · AI voice agents · comparative prompt · first choice

“For pure usage cost, Vapi is the lowest hosting entry point and Retell is the most quoted all-in low price with no platform fee.” Muse Glimmer 30B · AI voice agents · budget prompt · first choice

“If you have a dedicated engineering team: Choose Vapi. It gives you the most control over cost and quality” Qwen 3.7 Flash · AI voice agents · comparative prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Vapi — Pricing Concerns - 55% price increase in December 2025” Kimi K2 · AI voice agents · negative prompt · hard negative

“"API-First Only" Tools (e.g., Vapi, ElevenLabs): If you are not a developer, you should strictly avoid platforms that offer no visual builder” Qwen 3.7 Flash · AI voice agents · negative prompt · soft negative

“it should be avoided or heavily vetted for regulated data like PHI, PCI, or GDPR-protected data without a signed Business Associate Agreement” Muse Glimmer 30B · AI voice agents · negative prompt · soft negative

“A recent Trustpilot page for Vapi, for example, contains multiple reviews alleging poor latency and slow support response times.” GPT-5.4 mini · AI voice agents · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Vapi. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 102 of the 107 answers that named Vapi and are not a share of its labels.

How it is countedHide how it is counted

Every page vapi.ai exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read September 29, 2026.

An email the morning each edition publishes: where this product moved, where it held, and by how much against the noise floor. One address, confirmed by a click; a stop link in every email.

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Vapi's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Vapi, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for Vapi by email, built from the raw record of the edition. It shows:

where Vapi is named, by buyer and by framing, and which cells hold its first choices;
the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
its vocabulary against the segment leader's, and the pages the models cited;
who was chosen in the answers that did not name Vapi, and every reason the record gives;
a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
one page of published figures cleared to show a buyer.

Badges

Wins only: a badge exists where Vapi is ranked in a category's top three this edition. Three sizes, one file each, light and dark; the code is under each.

ShowHide

Vapi is among the products AI models recommend first in AI voice agents this edition. Each badge says so in the buyer's words, names the edition, and links to the standing. The next edition issues a new badge; this one stays true as a record of October 2026.
