RAG Architecture: A Production-Ready Guide

By PROTYPAI Team

What is RAG?

Retrieval-Augmented Generation combines vector search for relevant context with LLM processing to generate accurate, grounded responses.

Core Components

1. Data Ingestion Pipeline

  • Document parsing (PDF, Markdown, HTML, etc.)
  • Chunking strategy (semantic vs fixed-size)
  • Embedding generation with domain-specific models
  • Vector database storage and indexing
  • 2. Retrieval Layer

  • Semantic search using vector similarity
  • Hybrid search combining vector + keyword
  • Reranking for relevance optimization
  • Context selection and compression
  • 3. Generation Layer

  • Prompt engineering with retrieved context
  • LLM integration with streaming support
  • Response formatting and validation
  • Quality control and fact-checking
  • Production Considerations

  • Monitor retrieval quality with relevance metrics
  • Implement caching for common queries
  • Optimize costs with selective model usage
  • Handle edge cases with fallback strategies
  • Version control for prompts and configurations
