Apply Your Knowledge

Project Ideas

  1. Build a Documentation Assistant

    • Index your company's docs
    • Implement hybrid search
    • Add user feedback loop
  2. Create a Code Q&A System

    • Chunk code intelligently
    • Use code-specific embeddings
    • Handle multi-file questions
  3. Develop a Customer Support Bot

    • Integrate with ticketing system
    • Track conversation context
    • Implement escalation logic

Key Takeaways

Topic Remember
Architecture Start simple, add complexity as needed
Embeddings Match model to your domain
Chunking Preserve semantic boundaries
Hybrid Search Always use for production
Reranking Worth the latency cost
Evaluation Automate with RAGAS
Production Design for failure

Common Pitfalls to Avoid

❌ Starting with complex architectures
   ✅ Begin with simple RAG, iterate based on metrics

❌ Using default chunking
   ✅ Tune chunk size and overlap for your content

❌ Ignoring evaluation until production
   ✅ Set up RAGAS from day one

❌ Over-indexing everything
   ✅ Curate and clean your knowledge base

❌ Skipping monitoring
   ✅ Track quality metrics alongside latency

Advanced AI Agent Systems

This course builds on your RAG knowledge to create:

  • Multi-agent architectures
  • Tool-using agents with RAG memory
  • Autonomous agent workflows
  • Agent evaluation and safety

RAG is a foundational component of production AI agents. Your mastery of retrieval, chunking, and evaluation translates directly to building more sophisticated systems.

Additional Resources

Papers to Read:

  • "Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks" (Original RAG paper)
  • "REPLUG: Retrieval-Augmented Black-Box Language Models"
  • "Self-RAG: Learning to Retrieve, Generate, and Critique"

Tools to Explore:

  • LangSmith for tracing and evaluation
  • Langfuse for open-source observability
  • Ragas for automated metrics
  • Weaviate, Qdrant, Pinecone for vector databases

Communities:

  • LangChain Discord
  • Pinecone Community
  • MLOps Community Slack

Your RAG Checklist

Before deploying to production, ensure you have:

  • Retrieval: Hybrid search with reranking
  • Chunking: Optimized for your content type
  • Evaluation: RAGAS pipeline in CI/CD
  • Monitoring: Latency, quality, and cost dashboards
  • Reliability: Fallbacks and circuit breakers
  • Testing: 50+ question test set
  • Documentation: System architecture documented

Final Thoughts

RAG has become the standard pattern for grounding LLMs with external knowledge. The techniques you've learned—hybrid search, reranking, evaluation, and production optimization—are what separate prototype RAG systems from production-ready ones.

The field evolves rapidly. New embedding models, retrieval techniques, and architectures emerge regularly. Keep experimenting, measure everything, and iterate based on data.

Remember: The best RAG system is one that actually helps your users. Start with their needs, measure what matters, and optimize relentlessly.

Good luck building amazing RAG systems!
