02What they warned about

Zero 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, Mistral Small, DeepSeek V4 Flash, Llama 4 Maverick, 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.

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 B2B payment acceptance platform for a mid-market B2B company?”Paraphrase“Which accounts receivable payment portal would you recommend to a mid-sized B2B company?”Comparative“What are the top B2B payment platforms and how do they differ?”Budget-constrained“What is the best B2B payment acceptance platform for a company with a limited budget?”Scale-constrained“We are a 500 person company evaluating a B2B payment acceptance platform.
