[DEP] Cohere Rerank 3 Model - English Free trial
By:
Rerank will return a sorted list of documents based on the semantic similarity between the query and documents.
Product Overview
This listing is deprecated. Please subscribe to the new Rerank 3 listing in the marketplace. Cohere's Rerank endpoint enables you to significantly improve search quality by augmenting traditional key-word based search systems with a semantic-based reranking system which can contextualize the meaning of a user's query beyond keyword relevance. Cohere's Rerank delivers much higher quality results than just embedding-based search, and it requires only adding a single line of code into your application.

Highlights
Cohere's Rerank endpoint can be applied to both keyword-based search systems and vector search systems. When using a keyword-based search engine, like Elasticsearch or OpenSearch, the Rerank endpoint can be added to the end of an existing search workflow and will allow users to incorporate semantic relevance into their keyword search system without changing their existing infrastructure. This is an easy and low-complexity method of improving search results by introducing semantic search technology into a user’s stack.
This endpoint is powered by our large language model that computes a score for the relevance of the query with each of the initial search results. Compared to embedding-based semantic search, it yields better search results — especially for complex and domain-specific queries.
Rerank supports JSON objects as documents where users can specify at query time the fields (keys) that semantic search should be applied over.
