+<Info>
+**`langchain-localai` is a 3rd party integration package for LocalAI. It provides a simple way to use LocalAI services in LangChain.**
+
+The source code is available on [GitHub](https://github.com/mkhludnev/langchain-localai)
+
+</Info>
+
+This notebook shows how to use [LocalAI Reranker API](https://localai.io/features/reranker/) for document compression and retrieval.
+Let's load the `LocalAIRerank` class. In order to use the `LocalAIRerank` class, you need to have the LocalAI service hosted somewhere and configure the reranker. See the documentation at [localai.io/basics/getting_started/index.html](https://localai.io/basics/getting_started/index.html) and [localai.io/features/reranker/index.html](https://localai.io/features/reranker/index.html).
+
+```python
+pip install -U langchain-localai
+```
+
+```python
+import os
+from langchain_localai import LocalAIRerank
+from langchain_core.documents import Document
+
+# Set your LocalAI/OpenAI API key as an environment variable for security.
+# For example, in your shell: export OPENAI_API_KEY="your-key-here"
+reranker = LocalAIRerank(
+    openai_api_key=os.environ.get("OPENAI_API_KEY"),
+    model="bge-reranker-v2-m3",
+    openai_api_base="http://localhost:8080",
+)
+reranked_docs = reranker.compress_documents(
+    documents=[
+        Document(page_content="Green tea is rich in antioxidants and may improve brain function."),
+        Document(page_content="Coffee contains caffeine and can increase alertness."),
+        Document(page_content="Black tea has a strong flavor and contains various polyphenols."),
+    ],
+    query="What are the health benefits of green tea?"
+)
+```
