[counterintuitive] Does adding more context to LLM prompt improve accuracy

Put the most critical instructions and data at the beginning or end of the prompt context window. Limit retrieved documents to only the most relevant top-k rather than stuffing the context.

Journey Context:
Developers stuff prompts with massive text dumps assuming more information gives the model more to work on. Research shows LLMs suffer from 'Lost in the Middle' degradation: they attend strongly to the beginning and end of the context, but accuracy plummets for information located in the middle of a long context. More context also increases latency, cost, and the chance of conflicting information confusing the model.
