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.

“Arista EOS + CloudVision Portal for a greenfield or data-center-focused shop: mature EVPN/VXLAN, CLI familiar, CloudVision management/telemetry overlay, and lower operational overhead” Muse Glimmer 30B · Data center networking · paraphrase prompt · first choice

“Arista is positioned as AI-first with ultra-low-latency AI/ML fabrics, hyperscaler pedigree... AI training clusters favor Arista's buffering and EOS” Muse Glimmer 30B · Data center networking · comparative prompt · first choice

“platforms from Arista (CloudVision), Juniper (Apstra), or Cisco (with careful evaluation) are considered more mature and widely supported” Mistral Small · Data center networking · negative prompt · first choice

“Best-in-class data center focus, EOS is Linux-based and highly automatable, strong cloud/AI pedigree, competitive pricing, compact designs” DeepSeek V4 Flash · Data center networking · scale 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.

“Cisco ACI, Nexus 9000 with extensive features enabled, or overly rich SD‑N stacks can introduce configuration‑driven bugs if not fully tested.” GLM 4.7 FlashX · Data center networking · negative prompt · soft negative

“"Only a few, such as Arista Networks and Extreme Networks, continue to rely on partnerships."” Muse Glimmer 30B · SD-WAN · negative prompt · soft negative

“Cons: Premium cost; overkill for basic mid-market unless high-speed uplinks needed.” Grok 4.20 · Data center networking · direct prompt · soft negative

“one-half to one-third what a comparable Cisco Catalyst or Arista switch runs” Muse Glimmer 30B · Data center networking · budget prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Arista Networks. 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 101 of the 114 answers that named Arista Networks and are not a share of its labels.

How it is countedHide how it is counted

Every page arista.com 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.

Is this your product?

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 Arista Networks'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 Arista Networks, 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 Arista Networks by email, built from the raw record of the edition. It shows:

where Arista Networks 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 Arista Networks, 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 Arista Networks is ranked in a category's top three this edition. Three sizes, one file each, light and dark; the code is under each.
