Retriever is a collection of industry-leading models delivering 50% better accuracy, 15x faster multimodal PDF extraction, and 35x better storage efficiency, enabling enterprises to build retrieval-augmented generation (RAG) pipelines that provide real-time business insights. NeMo Retriever ensures data privacy and seamlessly connects to proprietary data wherever it resides, empowering secure, enterprise-grade retrieval. NeMo Retriever serves as a core component for NVIDIA AI-Q—a blueprint for building intelligent AI agents—and the NVIDIA RAG blueprint, enabling access to knowledge from enterprise AI data platforms. It provides a reliable foundation for scalable, production-ready retrieval pipelines supporting advanced AI applications.
NeMo Retriever microservices set a new standard for enterprise RAG applications, leading the industry with first-place performance across three top visual document retrieval leaderboards (ViDoRe V1, ViDoRe V2, and MTEB VisualDocumentRetrieval).
Documentation
Build world-class information retrieval pipelines and AI query engines with scalable data extraction and high-accuracy embedding and reranking.
Ingestion
Rapidly ingest massive volumes of data and extract text, graphs, charts, and tables at the same time for highly accurate retrieval.
Embedding
Boost text question-and-answer retrieval performance, providing high-quality embeddings for many downstream natural language processing (NLP) tasks.
Reranking
Enhance retrieval performance further with a fine-tuned reranking model, finding the most relevant passages to provide as context when querying a large language model (LLM).
How NVIDIA NeMo Retriever Works
NeMo Retriever provides components for building data extraction and information retrieval pipelines. The pipeline extracts structured and unstructured data (ex. text, charts, tables), converts it to text, and filters out duplicates. A NeMo Retriever embedding NIM converts the chunks into embeddings and stores them in a vector database, accelerated by NVIDIA cuVS, for enhanced performance and speed of indexing and search.
NeMo Retriever parse, a VLM-based OCR microservice for text and table extraction, preserves semantic structure, transcribes document images into text in reading order, classifies content types, and outputs structured markdown to retain spatial layout and formatting.
When a query is submitted, the system retrieves relevant information using vector similarity search, and then a NeMo Retriever reranking NIM reranks the results for accuracy. With the most pertinent information, an LLM NIM generates a response that’s informed, accurate, and contextually relevant. You can use various LLM NIM microservices from the NVIDIA API catalog to enable additional capabilities, such as synthetic data generation.

Ethical AI
NVIDIA’s platforms and application frameworks enable developers to build a wide array of AI applications. Consider potential algorithmic bias when choosing or creating the models being deployed. Work with the model’s developer to ensure that it meets the requirements for the relevant industry and use case; that the necessary instruction and documentation are provided to understand error rates, confidence intervals, and results; and that the model is being used under the conditions and in the manner intended.
