Movement

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

By model

How each model treated VMware Tanzu across every prompt where it was named for a mid-market B2B company. Twelve 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.

“Multi\u2011cloud, hybrid, consistent policies across clouds” GLM 4.7 FlashX · Managed Kubernetes · scale prompt · alternative

“Strongest VMware/hypervisor integration” MiniMax M2.5 · Managed Kubernetes · comparative prompt · alternative

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.

“Avoid Tanzu unless your organization has a massive budget and a deep, unmovable commitment to the legacy VMware ecosystem” Gemini 3.5 Flash · Managed Kubernetes · negative prompt · hard negative

“Multi-cloud abstraction layers (like Rancher or VMware Tanzu) add complexity that mid-market teams rarely need.” Kimi K2 · Managed Kubernetes · direct prompt · hard negative

“Verdict: Avoid unless you're deeply embedded in VMware with no migration path.” Kimi K2 · Managed Kubernetes · negative prompt · hard negative

“Also a wrapper layer; the caution is mainly added complexity and ecosystem coupling” Perplexity Sonar · Managed Kubernetes · negative prompt · soft negative

Named alongside

The products named in the same answers as VMware Tanzu, over the 32 answers that named it. Took the first choice instead counts the answers where the other product was the first choice and VMware Tanzu was named but was not.

A head-to-head page exists where both products are in a category's top three. 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 VMware Tanzu. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 25 of the 32 answers that named VMware Tanzu and are not a share of its labels.

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 VMware Tanzu'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 VMware Tanzu, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at vmware.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
