Reranking Model
A model that performs a second-stage ranking of candidate results after the retrieval recall stage, typically based on finer-grained semantic matching to improve ranking quality.
Timeline (last 90 days)
Reranking models score the query and document together, capturing finer-grained relevance signals, but inference must be run in real time at query time, resulting in higher latency.
Agent memory retrieval usually adopts a hybrid strategy: vector retrieval captures semantic similarity, metadata filtering narrows the candidate set, and a reranking model performs the final ranking based on task context and preference weights.
Zero-shot/NLI classifiers, embedding models, cross-encoders, and reranking models have for years supported label definition at inference time and output of constrained probability distributions, overlapping heavily with the core features Jev claims.
