Retrieval-Augmented Generation (RAG) Resources

GenAI has a trust problem—hallucinations, governance risks, and unreliable outputs. Retrieval-Augmented Generation (RAG) provides domain-specific data to enhance accuracy, governance, and performance. Learn how vector, relational, and graph RAG improve AI outcomes.

Why GenAI Needs RAG

GenAI models

speculate or fabricate responses due to probabilistic reasoning

Companies struggle

with hallucinations, governance risks, and inaccurate results

Unstructured data

remains untapped and difficult to integrate into AI workflows

What is RAG?

RAG or Retrieval-Augmented Generation is like an “Open-Book Test” for AI.

  • Instead of guessing, GenAI retrieves relevant, domain-specific data before generating responses.
  • The result? More accurate, governed, and context-aware AI outputs.
  • RAG reduces fine-tuning efforts, improves trust, and minimizes hallucinations.

How It Works

  • AI queries a vector, relational, or graph database for accurate context.
  • The retrieved information enhances the prompt before generating an answer.
  • The model produces fact-based, trustworthy responses.

RAG provides a strong foundation for Responsible AI.

Vespa at a Glance

Fully Integrated Platform

Vespa delivers all the building blocks of an AI application, including vector database, hybrid search, retrieval augmented generation (RAG), natural language processing (NLP), machine learning, and support for large language models (LLM).

Integrate all Data Sources

Build AI applications that meet your requirements precisely. Seamlessly integrate your operational systems and databases using Vespa’s APIs and SDKs, ensuring efficient integration without redundant data duplication.

Search Accuracy

Achieve precise, relevant results using Vespa’s hybrid search capabilities, which combine multiple data types—vectors, text, structured, and unstructured data. Machine learning algorithms rank and score results to ensure they meet user intent and maximize relevance.

Natural Language Processing

Enhance content analysis with NLP through advanced text retrieval, vector search with embeddings and integration with custom or pre-trained machine learning models. Vespa enables efficient semantic search, allowing users to match queries to documents based on meaning rather than just keywords.

Visual Search

Search and retrieve data using detailed contextual clues that combine images and text. By enhancing the cross-referencing of posts, images, and descriptions, Vespa makes retrieval more intelligent and visually intuitive, transforming search into a seamless, human-like experience.

Fully Managed Service

Ensure seamless user experience and reduce management costs with Vespa Cloud. Applications dynamically adjust to fluctuating loads, optimizing performance and cost to eliminate the need for over-provisioning.

High Performance at Scale

Deliver instant results through Vespa’s distributed architecture, efficient query processing, and advanced data management. With optimized low-latency query execution, real-time data updates, and sophisticated ranking algorithms, Vespa actions data with AI across the enterprise.

Always On

Deliver services without interruption with Vespa’s high availability and fault-tolerant architecture, which distributes data, queries, and machine learning models across multiple nodes.

Secure and Governed

Bring computation to the data distributed across multiple nodes. Vespa reduces network bandwidth costs, minimizes latency from data transfers, and ensures your AI applications comply with existing data residency and security policies. All internal communications between nodes are secured with mutual authentication and encryption, and data is further protected through encryption at rest.

Why RAG Matters for Your Business

Reduces hallucinations by grounding AI in real data.

Automates AI-assisted workflows with governed, reliable outputs.

Delivers more useful AI responses, reducing manual corrections.

Enables AI-driven sales, customer service, and decision-making.

Ensures governance, ethics, and compliance.

Better AI adoption, improved automation, and increased ROI.
