Movement

This is the first edition on this tier, so no move can be computed for Azure Cosmos DB yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated Azure Cosmos DB across every prompt where it was named for a mid-market B2B company. Twelve 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.

“managed NoSQL databases like MongoDB Atlas, Amazon DynamoDB, or Azure Cosmos DB are often good choices” MiniMax M2.5 · NoSQL · scale prompt · first choice

“MongoDB Enterprise Advanced and Azure Cosmos DB are the top choices” Mistral Small · NoSQL · direct prompt · first choice

“Cosmos DB (if you are on Azure): It offers multi-model capabilities... ideal for mid-market B2B SaaS platforms that serve global enterprise clients” Gemini 3.5 Flash · NoSQL · direct prompt · alternative

“If you need global multi‑region replication and are willing to pay a premium, Azure Cosmos DB (MongoDB or Table API) is worth a look.” MiniMax M2.5 · NoSQL · paraphrase prompt · alternative

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.

“Proprietary APIs (e.g., DynamoDB, Cosmos DB) offer convenience but make migration hard.” Kimi K2 · NoSQL · scale prompt · soft negative

“extremely difficult and expensive to migrate away from once you are locked in” Qwen 3.7 Flash · Managed databases · scale prompt · soft negative

Named alongside

The products named in the same answers as Azure Cosmos DB, over the 75 answers that named it. Took the first choice instead counts the answers where the other product was the first choice and Azure Cosmos DB was named but was not.

What carried it into the answer

The sites and pages cited by the answers that named Azure Cosmos DB. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 56 of the 75 answers that named Azure Cosmos DB 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 Azure Cosmos DB'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 Azure Cosmos DB, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at azure.cn is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
