What the models said for it

Verbatim evidence the judge attached to positive labels.

“For a very limited budget, starting with Guardrails AI (free/open source) or the free tiers of platforms like Strac would be sensible.” MiniMax M2.5 · AI governance · budget prompt · first choice

“The best AI governance platform for a company with a limited budget is Guardrails AI, which is free and open source.” Llama 4 Maverick · AI governance · budget prompt · first choice

“Best for: Teams building or using GenAI applications who need immediate runtime safety” GLM 4.7 FlashX · AI governance · direct prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

No model argued against it.

What carried it into the answer

The sites and pages cited by the answers that named Guardrails AI. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 11 of the 14 answers that named Guardrails AI and are not a share of its labels.
