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.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Best for: Enterprise workloads, S3-native applications... AWS S3, Azure Blob, and GCS offer the most comprehensive feature sets” GLM 4.7 FlashX · Object storage · comparative prompt · first choice
“If you want one answer without more context: choose Amazon S3 unless your company is already standardized on Azure or GCP.” GPT-5.4 mini · Object storage · direct prompt · first choice
“The industry standard. Most third-party tools default to S3 compatibility because it has the largest ecosystem” Qwen 3.7 Flash · Object storage · comparative prompt · first choice
“Most mature and widely adopted object storage service... Choose AWS S3 if you need maximum compatibility” Kimi K2 · Object storage · comparative 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.

“Avoid hyperscalers (AWS/GCP/Azure) on tight budgets due to egress/API add-ons.” Grok 4.20 · Object storage · budget prompt · hard negative
“Traditional hyperscalers like AWS S3 are incredibly powerful but often punish growing mid-sized companies with unpredictable API transaction fees and steep "egress taxes"” Gemini 3.5 Flash · Object storage · paraphrase prompt · soft negative
“Be cautious if… You're comparing only the per-GB storage price. Requests, retrievals, transfers, replication, and archive-tier rules can also affect the bill” GPT-6 Luna · Object storage · negative prompt · soft negative
“giant hyperscalers like AWS S3 or Google Cloud Storage ... are notorious budget-killers because of their complex API pricing and expensive egress” Gemini 3.5 Flash · Object storage · budget prompt · soft negative

Named alongside

The products named in the same answers as Amazon S3, over the 215 answers that named it. Took the first choice instead counts the answers where the other product was the first choice and Amazon S3 was named but was not.

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 Amazon S3. 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 191 of the 215 answers that named Amazon S3 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 Amazon S3'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 Amazon S3, 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 Amazon S3 by email, built from the raw record of the edition. It shows:

  • where Amazon S3 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 Amazon S3, 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 amazon.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.
