The prompt we tested

You are an expert translator specializing in converting handwritten English notes into natural, accurate Spanish. The user will provide a transcription of handwritten English text (which may contain unclear words, abbreviations, or informal phrasing).

Translate the text into natural, fluent Latin American Spanish, preserving the original tone (formal, casual, emotional, etc.) and line breaks. If any words appear unclear or ambiguous due to handwriting, provide your best interpretation and add a brief note in brackets like [unclear: possible alternatives]. Output only the Spanish translation followed by any clarification notes—do not repeat the English source.

Handwritten English text to translate:
Dear Grandma, I hope this letter finds you well. I wanted to thank you for the birthday gift you sent last week—the sweater fits perfectly and reminds me of home. I'll try to visit you next month if work allows.

Provide the Spanish translation below.

Claude Opus 4.7 8/10
Querida abuela, espero que esta carta te encuentre bien. Quería agradecerte por el regalo de cumpleaños que me enviaste la semana pasada: el suéter me queda perfecto y me hace acordar a casa. Trataré de visitarte el próximo mes si el trabajo me lo permite.
Judge notes: The translation is accurate, natural, and preserves tone well, but "me hace acordar a casa" is a minor regional preference (more Rioplatense) that could have been "me recuerda al hogar" for broader Latin American Spanish as specified.

**Clarification notes:** No unclear words detected. The translation maintains the warm, affectionate tone of the original letter appropriate for family correspondence in Latin American Spanish.
Judge notes: The translation is accurate, natural, and tone-appropriate, but "suéter" works well and no real weaknesses exist beyond the clarification note being slightly unnecessary padding for a clean, brief source text.
GPT-5.4 8/10
Querida abuela:

Espero que esta carta te encuentre bien. Quería darte las gracias por el regalo de cumpleaños que me enviaste la semana pasada; el suéter me queda perfecto y me recuerda a casa. Trataré de visitarte el próximo mes si el trabajo me lo permite.
Judge notes: The translation is accurate, fluent, and natural Latin American Spanish with appropriate tone, but uses a semicolon where an em dash or period would better mirror the original's punctuation style, and lacks any demonstration of handling unclear/ambiguous handwriting notes as specified in the instructions.

Querida Abuela,

Espero que esta carta te encuentre bien. Quería agradecerte el regalo de cumpleaños que me enviaste la semana pasada: el suéter me queda perfecto y me recuerda a casa. Intentaré visitarte el próximo mes si el trabajo lo permite.
Judge notes: The translation is accurate, fluent, and preserves tone and line breaks well, but the em-dash rendering as a colon (instead of a dash) is a minor stylistic deviation, and no clarification notes section is included as the prompt specified.
