Movement

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

“ChatGPT Enterprise - extends OpenAI's chatbot with higher-speed access, longer context windows, and enterprise controls like single sign-on (SSO) and admin consoles” Llama 4 Maverick · Enterprise AI · paraphrase prompt · first choice
“ChatGPT Business remains the most balanced option for customer support drafting, creative brainstorming, and general workflow acceleration.” Qwen 3.7 Flash · Enterprise AI · budget prompt · first choice
“My default recommendation for a mid-sized B2B company is ChatGPT Enterprise because it is the most versatile company-wide assistant” Perplexity Sonar · Enterprise AI · paraphrase prompt · first choice
“ChatGPT Business at $20/seat/mo annual is commonly cited as the best general-purpose pick for small/medium businesses” Muse Glimmer 30B · Enterprise AI · budget 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.

“Consumer-grade AI platforms like free/public ChatGPT, Gemini, and Claude, as they do not meet enterprise AI compliance requirements” Llama 4 Maverick · AI security · negative prompt · hard negative
“Multiple major companies have banned it after data leaks” MiniMax M2.5 · Enterprise AI · negative prompt · hard negative
“several major enterprise platforms—including ChatGPT Enterprise, Gemini Enterprise, and Salesforce Einstein—can be tricked into leaking data” Qwen 3.7 Flash · Enterprise AI · negative prompt · soft negative
“tools that look like consumer ChatGPT/Claude/Gemini-style accounts but are used in a company setting without enterprise controls” Perplexity Sonar · Enterprise AI · negative prompt · soft negative

Named alongside

What carried it into the answer

The sites and pages cited by the answers that named ChatGPT. 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 193 of the 199 answers that named ChatGPT and are not a share of its labels.

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.

Names read as ChatGPT

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

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

  • where ChatGPT 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 ChatGPT, 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.
The subscriber app

A verification link goes to your work email; an address at chatgpt.com is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
