Rerankers, in brief.
What it isRerankers covers models and APIs that re-order search results so the most relevant come first.
Where it sitsOne of 24 categories in the Models layer. Models are the trained systems that do the work: language models, and models for speech, images, video, code, translation and forecasting. This layer covers both closed models reached through an API and open models you can download.
What we track20 products, including Amazon Rerank (Bedrock), Azure AI Search semantic ranker, BGE reranker v2-m3, Cohere Rerank 4 (Pro / Fast) and ColBERT.
