Rank = position among every model config we tested in that task area (lower is better). Sorted by biggest gap first.
Same task, both models — judged
Both models answered the same test case; an independent judge graded each. Quotes are the judge's actual rationale.
Translation & Localization
Marketing copy, natural not literal (EN→French) (Business Translation)
“While the model provides highly fluent, natural, and creative French marketing copy that avoids literal translationese, its primary recommendation completely drops the word 'plastic'. Since avoiding plastic is a key selling point of the source text, this is a major omission error. Only Option 2 successfully captures all elements of the source text.”
“The translation is accurate, fluent, and perfectly captures the marketing tone without resorting to a literal calque.”
