# Retrieval Augmented Generation (RAG)

**Retrieval Augmented Generation (RAG)** is an AI architecture that combines the capabilities of large language models (LLMs) with external knowledge retrieval systems to provide more accurate, up-to-date, and contextually relevant responses. Unlike traditional language models that rely solely on their pre-trained knowledge, RAG systems can access and incorporate external information sources in real-time.

## Definition and Core Concept

RAG works by first retrieving relevant information from external knowledge sources (such as databases, documents, or the web) and then using that retrieved information to augment the language model's response generation. This approach addresses key limitations of traditional LLMs, including:

- **Knowledge Cutoff**: Access to information beyond the model's training data
- **Factual Accuracy**: Ability to cite specific sources and verify information
- **Current Information**: Access to real-time or frequently updated data
- **Domain Expertise**: Specialized knowledge for specific business contexts

### How RAG Works

1. **Query Processing**: The user's question or prompt is analyzed
2. **Information Retrieval**: Relevant documents or data are retrieved from external sources
3. **Context Augmentation**: Retrieved information is combined with the original query
4. **Response Generation**: The LLM generates a response using both the original query and retrieved context
5. **Source Attribution**: Responses can include citations to the source materials

## Key Components of RAG Systems

### 1. Retrieval System

The retrieval component is responsible for finding relevant information from external sources:

- **Vector Database**: Stores document embeddings for semantic search
- **Search Algorithms**: Implements various retrieval methods (dense retrieval, sparse retrieval, hybrid)
- **Document Processing**: Handles document ingestion, chunking, and indexing
- **Relevance Scoring**: Ranks retrieved documents by relevance to the query

### 2. Generation System

The generation component uses the retrieved information to create responses:

- **Language Model**: Large language model (e.g., GPT, Claude, LLaMA)
- **Context Integration**: Combines retrieved information with the original query
- **Response Formatting**: Structures the output appropriately
- **Source Attribution**: Includes references to source materials

### 3. Knowledge Base

The external information sources that the system can access:

- **Document Collections**: PDFs, Word documents, web pages
