October 2026 Edition. Every number here is derived from the raw labels under vendor table v2026-10.8, every buyer segment counted.

Standing

6 labels, too few to rank

A product needs 10 labels in a category before a share or quadrant is stated. Xen was named 6 times in Server virtualization, where Proxmox VE led with 42%. The labels and the evidence are below, counted exactly.

Standing by category

Every category where a model named Xen for a mid-market B2B company. Share is first choices across the direct, paraphrase, budget and scale prompts; rank is within every product named in that category.

Movement

This is the first edition on this tier, so no move can be computed for Xen 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 Xen 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.

No positive label carried a quote.

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.

“If you're using Xen, be especially cautious with older branches or configurations that rely on deprecated features.” GPT-5.4 mini · Server virtualization · negative prompt · soft negative

“Another free, open-source hypervisor option, though it has a steeper learning curve.” Claude Haiku 4.5 · Server virtualization · budget prompt · soft negative

“Functional but legacy status; prefer KVM-based alternatives for new deployments.” Kimi K2 · Server virtualization · negative prompt · soft negative

“Open-Source Pitfalls (e.g., raw KVM/QEMU, older Xen): Free but require expertise” Grok 4.1 Fast · Server virtualization · negative prompt · soft negative

Named alongside

The products named in the same answers as Xen, over the 11 answers that named it. Took the first choice instead counts the answers where the other product was the first choice and Xen was named but was not.

A head-to-head page exists where both products are among a category's top eight. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

The sites and pages cited by the answers that named Xen. 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 9 of the 11 answers that named Xen and are not a share of its labels.

Names read as Xen

What the judge wrote, as written, with how often. The vendor table decides that these count as Xen; a claim can dispute any of them.

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

where Xen 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 Xen, 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.
