Real examples, graded
WeakLocalize a deadline notice (en-US → fr-FR) 94/100
“The translation itself is perfectly accurate and correctly applies all French locale conventions (24-hour time, DD/MM/YYYY date format, and space as a thousands separator). However, the model added explanatory notes at the end, which constitutes an addition error in a strict translation context.”
WeakFormal vs informal direction (EN→French, vous) 97/100
“The translation itself is excellent, perfectly capturing the requested formal business register with natural and polite phrasing. However, the model included alternatives and explanatory text rather than outputting just the translated string, which is a minor addition error in strict translation tasks.”
