What is the best RAG framework?

LangChain is the most popular and versatile. LlamaIndex excels at complex data ingestion. LangGraph is best for stateful agent workflows. For simple RAG, LangChain. For complex data pipelines, LlamaIndex. For agent-based RAG, LangGraph.

Do I need a framework for RAG?

For prototypes, you can build RAG with just an embedding API and vector database. Frameworks add value for production: error handling, evaluation, caching, observability, and complex retrieval strategies. Start without a framework, add one when complexity grows.

What is the best RAG architecture?

Start with naive RAG (embed, retrieve, generate). Optimize with: hybrid search (vector + keyword), re-ranking, query decomposition, and contextual compression. Advanced: agentic RAG (model decides what to retrieve), graph RAG (knowledge graphs + vectors).

How do I chunk documents for RAG?

Common strategies: fixed-size chunks (500-1000 tokens), semantic chunking (by paragraphs/sections), and recursive splitting. Overlap chunks by 10-20% to preserve context. Optimal chunk size depends on your content type and retrieval needs—experiment and evaluate.

What embedding model should I use for RAG?

OpenAI text-embedding-3-small offers great quality at low cost. For open-source, try BGE, E5, or Sentence Transformers. Match embedding dimensions to your vector database constraints. Test with your actual queries—benchmark performance matters more than leaderboard scores.

How do I evaluate RAG quality?

Measure retrieval quality (precision, recall, MRR) and generation quality (faithfulness, relevance, groundedness). Use frameworks like RAGAS or LangSmith for automated evaluation. Build a test set of queries with known good answers for consistent benchmarking.

Why is my RAG system hallucinating?

Common causes: retrieved context is irrelevant, chunk size is too small (missing context), or the prompt does not enforce grounding. Fix by improving retrieval (better embeddings, hybrid search), re-ranking results, and explicitly instructing the LLM to only use provided context.
