Report #68746

[counterintuitive] Should I include as much context as possible in the LLM prompt

Place the most critical instructions and retrieved documents at the very beginning or end of the prompt context window. Avoid burying crucial information in the middle of long contexts.

Journey Context:
Developers stuff prompts with massive retrieved documents, assuming the LLM will scan them like a database. LLMs suffer from severe 'Lost in the Middle' degradation; their attention mechanisms disproportionately weigh the start and end of the context, completely ignoring information placed in the middle, leading to worse performance than using less context.
