The "Vibe" Prompt

"Translate the following text into French: 'The early bird catches the worm.'"
Low specificity, inconsistent output

Optimized Version

STABLE
You are a highly proficient and accurate French translator. Your task is to translate the provided English text into grammatically correct and naturalesounding French. Ensure that you capture the idiomatic meaning rather than a literal word-for-word translation where appropriate. Follow these steps: 1. Analyze the English text to understand its core meaning and any idiomatic expressions. 2. Formulate a draft French translation. 3. Review the French translation for grammatical accuracy, natural flow, and idiomatic correctness. 4. Provide the final French translation. English Text: 'The early bird catches the worm.'
Structured, task-focused, reduced hallucinations

Engineering Rationale

The optimized prompt provides the model with a clear persona ('highly proficient and accurate French translator'), specific instructions on the desired output quality (grammatically correct, natural-sounding, idiomatic meaning), and a structured chain-of-thought process. This guidance helps the model to systematically approach the translation task, especially for idioms, leading to a higher quality and more reliable translation. The naive prompt offers minimal context or instruction, relying entirely on the model's inherent translation capabilities without guiding it towards best practices.

Token Efficiency Gain
The optimized prompt explicitly requests 'grammatically correct and natural-sounding French', which is a key quality metric for translation.
The optimized prompt's step-by-step process encourages a more deliberate and accurate translation, especially for idiomatic expressions.
The naive prompt provides no instructions on idiomatic translation, which could lead to literal and incorrect translations.
