02What they warned about

Three of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, GPT-5.4 mini, Perplexity Sonar, Mistral Small, DeepSeek V4 Flash, Llama 4 Maverick, Qwen 3.7 Flash, 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.

29 of 47 labels negative · 12 of 12 models · 7 hard negative
“here are the bill pay platforms a large enterprise should **avoid or be cautious about**: - **Bill.com (BILL)** – Several sources highlight significant concerns” GLM 4.7 FlashX, negative prompt

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 bill pay platform for businesses for an enterprise B2B company?”Paraphrase“Which vendor payments software would you recommend to a large B2B company with thousands of employees?”Comparative“What are the top enterprise-grade bill pay platforms and how do they differ?”Budget-constrained“What is the best bill pay platform for businesses for a large company that needs predictable total cost across thousands of users?”Scale-constrained“We are a 5,000 person company with SSO, SOC 2 and procurement review requirements evaluating a bill pay platform for businesses.
