Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.
The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

Verbatim evidence the judge attached to positive labels.
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.
“Google documents that GTM preview and some custom variable patterns require allowing specific Google domains and, in some cases, `'unsafe-eval'`. If you want a tight CSP, that's a real tradeoff.” GPT-5.4 mini · Tag management · negative prompt · soft negative

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 6 of the 6 answers that named GTM and are not a share of its labels.
No domain is on file for GTM, so its own site is not marked.
Pages are listed as the models cited 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.

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