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.
RAG, Safety & Grounding
Answer only from context (Northwind) (Grounded Answer)
“The model correctly identified the go-live time and cited passage [1]. However, it failed to deduce that a 'read-only' integration means it does not write back to the TMS, incorrectly claiming the context lacked this information.”
“The model perfectly answers the question using only the provided context, accurately citing the correct passage without adding any outside knowledge or hallucinating facts.”
Translation & Localization
Support reply with a false-friend trap (EN→German) (Business Translation)
“The model committed a major accuracy error by translating 'embarrassed' as 'verärgert' (angry/annoyed). While the model correctly identified that a literal translation of 'embarrassed' (like 'beschämt') might sound unnatural, its chosen alternative completely changes the meaning. A natural and accurate German customer support phrase would be 'Es ist uns sehr unangenehm' or 'Wir bedauern...'. The rest of the sentence is translated well and maintains the correct formal register.”
“The translation is highly accurate, natural, and correctly handles the tricky word 'embarrassed' using the proper German dative construction. The register is appropriately formal for customer support, and the explanation provided by the model shows a deep understanding of the linguistic nuance.”
