02What they warned about

Three of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, Perplexity Sonar, Grok 4.1 Fast, Mistral Small, 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.

45 of 53 labels negative · 12 of 12 models · 14 hard negative
“LaunchDarkly** is generally not worth the cost for a team under 10 engineers with straightforward on/off flags” Claude Haiku 4.5, negative prompt

“Be most cautious with: ... enterprise experimentation platforms like Optimizely/Split \u2014 they're built for scale you don't have yet” DeepSeek V4 Flash, negative prompt
Unleash

5 of 44 labels negative · 4 of 12 models
“Targeting is typically user-level; B2B org-level targeting often requires extra work or custom attributes; limited analytics/experiments out of the box.” GLM 4.7 FlashX, paraphrase prompt

03What they cite

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.
