Reranking happens before the LLM call: the rerank model reads the question and the candidate chunks together and outputs a more precise ordering, and a common approach is to recall 10-20 and, after reranking, keep only 3-5 to send to the LLM, thereby reducing the number of context tokens and improving answer quality.

UnverifiedThe ReRankEval project uses a prompt-driven LLM reranker, allowing the large model to directly judge the relevance of each candidate document to the question and reorder them.72% similarVerifiedReranking uses a Cross-Encoder model to re-score and re-rank the candidate chunks recalled by Top-K, with precision far higher than that of a Bi-Encoder.70% similarVerifiedReranking is the process of using a fine-ranking model to re-score and re-sort candidate segments after an initial Top-K retrieval, in order to improve the quality of the context fed into the large model.70% similarVerifiedReranking is the step of performing a secondary sort on retrieval results to improve relevance.67% similarUnverifiedWhen a node simultaneously performs LLM calls and routing decisions, it leads to repeated evaluation of the same data or multiple LLM calls per step, dragging down token consumption.67% similar
