📰 Dev.to · saurabh naik

Learn how to optimize RAG performance with a practical chunking playbook, avoiding common pitfalls and improving evaluation metrics

intermediate Published 18 May 2026
Action Steps
  1. Apply semantic splitters to identify optimal chunk sizes
  2. Configure chunk size and overlap parameters to balance trade-offs
  3. Run a small evaluation harness in Python to test chunking strategies
  4. Test different chunking approaches to find the optimal solution
  5. Compare evaluation metrics to determine the most effective chunking method
Who Needs to Know This

Data scientists and machine learning engineers working with RAG models can benefit from this playbook to improve model performance and efficiency

Key Insight

💡 Semantic splitters may not always be the best approach, and chunk size and overlap parameters can significantly impact RAG performance
