What you get

A short Python script that sends a search query and six candidate documents to the Jina Reranker API and prints the four most relevant, best first, with their scores. Use it as the second stage after a vector or keyword search, to put the best chunks at the top before they go into your RAG prompt.

Jina's current reranker, jina-reranker-v3.5, is listwise: it reads the query and all your candidate documents in one context window (up to 131,072 tokens) and scores them against each other in a single pass, instead of scoring each document on its own. It is multilingual, so an English query can rank French, German and Chinese documents in the same call, as the example below does.

Prerequisites

Python 3.10 or newer (requests 2.34.2 declares requires_python >=3.10).
A Jina API key in JINA_API_KEY. Open the Reranker page (https://jina.ai/reranker/): new users get an auto-generated key with free tokens. Log in and manage keys at https://jina.ai/api-dashboard/key-manager so you do not lose it.
