The same question asked on behalf of a different buyer. Each standing is computed within its segment; they sit side by side and are never added together.

What they warned about

Six of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, GPT-5.4 mini, Gemini 3.5 Flash, DeepSeek V4 Flash, Qwen 3.7 Flash and Kimi K2 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.
Terraform
29%
26 of 89 labels negative · 14 of 12 models · 3 hard negative
“**Terraform Cloud/Enterprise**: Per-resource pricing scales unpredictably with infrastructure growth” Kimi K2, budget prompt

“These are often fine if you are deliberately standardized on one cloud, but they are risky if your enterprise needs consistent workflows across multiple clouds” GPT-5.4 mini, negative prompt

16 of 77 labels negative · 10 of 12 models · 2 hard negative
“If you use managed SaaS platforms like HCP Terraform ... or Pulumi Cloud at this scale, your pricing becomes highly volatile and prohibitively expensive.” Gemini 3.5 Flash, budget prompt

“Examples: Ansible, Chef, Puppet (when used for infrastructure provisioning rather than configuration management) ... Why be cautious” Kimi K2, negative prompt

What they cite

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

Sites the answers cite

75 of 84 answers in this category came back with a source list, from 14 of 12 models: citations where the model returns them, or the search results it consulted. 1150 links across 305 sites, every framing counted. Ranked by the number of answers carrying the site or page.

Pages the answers cite

The ten pages named in the most answers, by full address. A page here is one the models returned with a recommendation, not one the index endorses.

Search against answers

Each company's standing in the answers beside its site's footprint in Google search, one row a site: the products the models named on it with their shares, and the share they add up to; monthly searches on Google, and DataForSEO's estimate of AI search demand (modeled from search signals, directional, not a count of queries to any assistant), for the most-searched of the company's and its products' names (the name is in each row's hover text); estimated monthly organic visits to the site; and its best position in Google's top ten for “best infrastructure-as-code tool”, “infrastructure-as-code tool”, “infrastructure-as-code tools”. US estimates from DataForSEO and Google's Ads Transparency Center. A small company's site, or a mid-sized company's site for its flagship, is marked company; a product on a large parent's site (Google, Microsoft) has no site figures. A column with no figures for this category is left out, and an empty cell means none were seen, not none exist. Two measurements side by side: neither is read as the cause of the other.

How 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.
