Report #35227

[counterintuitive] Adding more context to the prompt always improves accuracy

Keep context strictly relevant; use retrieval score thresholds to exclude low-relevance chunks and place critical instructions at the beginning or end of the prompt.

Journey Context:
LLMs suffer from attention dilution. When irrelevant or excessively long context is added, accuracy on facts located in the middle of the context drops significantly \(the 'Lost in the Middle' phenomenon\). More tokens also increase latency, cost, and the chance of conflicting instructions.
