Standing

Standing by category

Every category where a model named ChatGPT 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.

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 10 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.

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.

“Examples: ChatGPT, TaxGPT, or other general-purpose AI tools - Why to avoid: These are designed for individual income tax questions, not multi-jurisdiction B2B sales tax compliance.” GLM 4.7 FlashX · Sales tax automation · negative prompt · hard negative

“This includes tools like ChatGPT (free/Plus tiers), Claude, and Gemini when used with sensitive data. ChatGPT hallucinates specific numbers and regulatory details with confidence” Claude Haiku 4.5 · AI accounting assistants · negative prompt · hard negative

“Best practice guidance is to keep client data out of general chat models and use sanitized or dummy data. ChatGPT hallucinates, and it sounds just as confident when it's wrong.” Muse Glimmer 30B · AI accounting assistants · negative prompt · hard negative

“Free or standalone chatbots like public ChatGPT/Claude-style tools when used with client data, because they may lack robust security and may use inputs for training.” Perplexity Sonar · AI accounting assistants · negative prompt · hard negative

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 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 19 of the 19 answers that named ChatGPT and are not a share of its labels.

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.
