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.

“Look instead for platforms built on open-source frameworks (like Meta’s Robyn or Google’s LightweightMMM)” Gemini 3.5 Flash · Attribution & MMM · negative prompt · alternative
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.

“rarely have full-time data scientists to manage open-source MMM code (like Google Meridian or Meta Robyn)” Gemini 3.5 Flash · Attribution & MMM · direct 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 64 of the 65 answers that named Meta Robyn and are not a share of its labels.
264 of the 264 domain citations in answers naming Meta Robyn came from somebody else's page.
Pages are listed as the models cited them.
Search figures are US estimates from DataForSEO, read September 28, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

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 Meta Robyn'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 Meta Robyn, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
A new claim receives the current edition's vendor brief for Meta Robyn by email, built from the raw record of the edition. It shows:
