+# LlamaIndex Postprocessor Integration: Jina AI Rerank
+
+Jina Rerank is based on [Jina Reranking](), which is a state-of-the-art reranking model in terms of
+
+1. Input context length - Jina Reranking is capable of accepting 8K-length input context
+2. Reranking performance - Jina Reranking outperforms other models on Mean Reciprocal Rank (MRR) and hit-rate, as shown in these [benchmarks]().
+
+Please pip install llama-index-postprocessor-jine-rerank to install Jina Rerank package.
