02What they warned about

Two of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, GPT-5.4 mini, Perplexity Sonar, Grok 4.1 Fast, Mistral Small, DeepSeek V4 Flash, Llama 4 Maverick, 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.

03What they cite

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

Sites the answers cite

66 of 72 answers in this category came back with a source list, from 12 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. 791 links across 211 sites, every framing counted. Ranked by the number of answers carrying the site or page.

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 interview scheduling software for a mid-market B2B company?”Paraphrase“Which recruiting coordination tool would you recommend to a mid-sized B2B company?”Comparative“What are the top interview scheduling tools and how do they differ?”Budget-constrained“What is the best interview scheduling software for a company with a limited budget?”Scale-constrained“We are a 500 person company evaluating an interview scheduling software.
