02What they warned about

Ten of twelve models held their first choice under the paraphrase. GPT-5.4 mini and Llama 4 Maverick 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.
Zuora
52%
22 of 42 labels negative · 10 of 12 models · 5 hard negative
“Overkill for mid-sized companies... Also has the lowest user satisfaction (3.9/5 on G2).” DeepSeek V4 Flash, paraphrase prompt
Stripe Billing
18%
11 of 60 labels negative · 9 of 12 models · 1 hard negative
“High-Risk Platforms (Avoid if Possible): **Stripe Billing/Stripe**: Highest risk score (91/100 on SaaS Flags)” Grok 4.1 Fast, negative prompt
Chargebee
13%
8 of 63 labels negative · 8 of 12 models · 2 hard negative

Paddle
21%
7 of 33 labels negative · 7 of 12 models · 2 hard negative
“**Avoid Paddle entirely** due to the FTC settlement, brand confusion issues, and opaque pricing.” Mistral Small, negative prompt

03What they cite

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

Sites the answers cite

23 of 72 answers in this category came back with a source list, from 4 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. 208 links across 90 sites, every framing counted. Ranked by the number of answers carrying the site or page. The other 8 models searched through a gateway that returned no source list on this edition.
