This tutorial demonstrates a practical implementation of an advanced multimodal RAG system using NVIDIA NeMo Retriever to handle complex document structures like tables and charts without relying on external GPU clusters. By leveraging hosted NIMs for dense retrieval, vision-language reranking, and grounded generation with inline citations, the workflow establishes a robust pattern for integrating high-fidelity AI components into production pipelines. The inclusion of metadata-filtered search and recall-at-k evaluation metrics provides actionable insights for optimizing retrieval quality in enterprise-grade applications.

Building a Multimodal RAG Pipeline with NVIDIA NeMo Retriever, Hosted NIMs, LanceDB, Reranking, and Grounded Generation

MarkTechPostAugust 7, 20263 min read

In this tutorial, we build an advanced multimodal retrieval-augmented generation pipeline with NVIDIA NeMo Retriever. We begin by configuring a Python 3.12 environment, installing the required packages, and performing offline PDF text extraction without relying on a GPU or external API key. We then extend the workflow with hosted NVIDIA NIM endpoints to detect page […] The post Building a Multimodal RAG Pipeline with NVIDIA NeMo Retriever, Hosted NIMs, LanceDB, Reranking, and Grounded Generation appeared first on MarkTechPost.
