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.

Basware

5 of 6 labels negative · 4 of 12 models · 4 hard negative

“Avoid dedicating your entire billing operations to an app with shallow customer support and a history of altering pricing terms mid-contract.” Gemini 3.5 Flash, negative prompt
