 This tutorial shows you how to implement retrieval-augmented generation (RAG) using Amazon OpenSearch and the [DeepSeek chat model](https://api-docs.deepseek.com/api/create-chat-completion).
 If you are not using Amazon OpenSearch, you can use the DeepSeek connector chat blueprint directly. For more information, see [the blueprint](https://github.com/opensearch-project/ml-commons/blob/main/docs/remote_inference_blueprints/deepseek_connector_chat_blueprint.md).
 
+For a simpler alternative, you can explore our Python-based implementation in this [demo notebook](DeepSeek_demo_notebook_for_RAG.ipynb).

 Note: Replace the placeholders starting with the prefix `your_` with your own values.
