Needle-in-a-Haystack
The “needle-in-a-haystack” problem refers to the challenge of retrieving specific, critical information (the “needle”) from a massive context window (the “haystack”) without degradation in performance. It is a key metric for evaluating long-context capabilities of Large Language Models (LLMs).
