Cohere Rerank API — Managed Reranking for Search & RAG

I will integrate the Cohere Rerank API into your retrieval pipeline — covering API authentication, result formatting for the Cohere API input format, response parsing, integration with your existing retrieval results, and cost monitoring for reranking API usage. Cohere Rerank offers managed reranking without the infrastructure overhead of self-hosting a cross-encoder model — a managed API call that accepts your query and retrieved documents and returns a reranked list, eliminating GPU inference infrastructure while delivering state-of-the-art reranking quality.

The integration covers Cohere API authentication, retrieved document formatting, reranking API call with error handling, response parsing and ranking extraction, cost tracking per reranking call, and precision improvement evaluation.
