Summary

A user studying Ancient Greek encountered difficulties using Claude Opus 4.6 to generate correct answers for a fill-in-the-blanks exercise from a textbook's Chapter 3. Despite the task being relatively simple and Ancient Greek texts being available online, Opus 4.6 made noticeable errors, even to a novice student. Attempts to improve performance by appending a "double-check" instruction or attaching a PDF textbook were unsuccessful. The core challenge is to devise a prompt that enables Claude Opus 4.6 to correctly complete the exercise, producing classical Attic Greek without errors, even for someone who does not understand Ancient Greek or know the correct answers themselves. The exercise involves filling blanks in sentences using a provided list of Greek words and their inflections.

Key takeaway

For NLP engineers developing language-specific applications, you should anticipate that even advanced models like Claude Opus 4.6 may require specialized prompting or external validation for seemingly straightforward tasks in less common languages. Consider implementing a multi-stage prompting strategy or integrating external linguistic tools to ensure accuracy, especially when the target language is outside the model's core strengths or when human verification is not feasible.

Key insights

AI models can struggle with specific, low-resource tasks even with general domain knowledge.

Principles

• AI performance varies by task difficulty.
• Direct instruction may not overcome inherent model limitations.

In practice

• Avoid relying on AI for unverified, critical language tasks.
• Test AI outputs against known correct answers when possible.

Topics

• Ancient Greek
• Claude Opus 4.6
• Prompt Engineering
