Prompt Repetition

Problem Being Solved

LLMs are trained as Causal Language Models, where each token attends only to previous tokens. This leads to:

1. Context-Question Problem: The question is unknown when processing context
2. Options-First MCQ Problem: Cannot fully understand the question context when viewing answer choices
3. Position/Index Problem: Attention weights weaken for specific position information in long lists

Prompt repetition enables the second pass to reference the entire first pass, effectively mimicking some benefits of bidirectional attention.
