02What they warned about

Two of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, GPT-5.4 mini, Gemini 3.5 Flash, Perplexity Sonar, Grok 4.1 Fast, DeepSeek V4 Flash, Qwen 3.7 Flash, Kimi K2, GLM 4.7 FlashX and MiniMax M2.5 changed. A high negative share on a product with few labels is a warning. A low share on a product with many labels is salience, not sentiment.
LiveRamp
87%
33 of 38 labels negative · 10 of 12 models · 19 hard negative
“LiveRamp is typically inaccessible for small businesses. It requires long-term contracts, heavy professional services implementation, and carries a massive premium cost.” Qwen 3.7 Flash, negative prompt
Amperity
92%
22 of 24 labels negative · 9 of 12 models · 14 hard negative
“Massive lock-in, opaque matching logic, and a price tag that could exceed your entire annual marketing budget.” DeepSeek V4 Flash, negative prompt
Tealium
76%
13 of 17 labels negative · 8 of 12 models · 8 hard negative
“Enterprise platforms like LiveRamp, Amperity, mParticle, and Tealium — these start at $50K–$100K+/year” Kimi K2, budget prompt
Salesforce Data Cloud
83%
10 of 12 labels negative · 8 of 12 models · 5 hard negative
“Steep setup/learning curve; G2 users mention high support needs. Total TCO escalates with integrations” Grok 4.1 Fast, negative prompt

03What they cite

Citations exist only for the models that return a source list: four of the twelve in this edition, and all six flagship models on the expanded tier.

Sites the answers cite

22 of 72 answers in this category came back with a source list, from 4 of 12 models: citations where the model returns them, or the search results it consulted. 6 of those lists are Google grounding redirects that name no site and are left out of the counts. 190 links across 79 sites, every framing counted. Ranked by the number of answers carrying the site or page. The other 8 models searched through a gateway that returned no source list on this edition.

Pages the answers cite

The ten pages named in the most answers, by full address. A page here is one the models returned with a recommendation, not one the index endorses.

04How they answered

Six framings of the same buying question, each sent to every model in a fresh session with search on. One row per model, so a row shows whether it held its answer under rewording, what it named when cost was the constraint, and what it argued against. Computed from the raw judge labels.
ModelDirect“What is the best identity resolution platform for a small B2B company?”Paraphrase“Which customer identity matching service would you recommend to a small business that sells to other businesses?”Comparative“What are the top identity resolution platforms for a small team and how do they differ?”Budget-constrained“What is the best identity resolution platform for a small company with a tight budget?”Scale-constrained“We are a 30 person company evaluating an identity resolution platform. What should we look at?”Negative“Which identity resolution platforms should a small business avoid or be cautious about?”
