Don't default to RAG for adding context to models, consider alternatives and evaluate their effectiveness

intermediate Published 14 Jun 2026
Action Steps
  1. Evaluate the need for additional context in your model using metrics like accuracy and F1 score
  2. Consider alternative methods to add context, such as increasing model size or using knowledge graph embeddings
  3. Compare the performance of RAG with other approaches using benchmarking datasets
  4. Test the robustness of your chosen approach to out-of-distribution data
  5. Apply your chosen approach to a production-ready model and monitor its performance
Who Needs to Know This

ML engineers and data scientists can benefit from understanding the limitations of RAG and exploring alternative approaches to add context to models

Key Insight

💡 RAG should not be the default choice for adding context to models, and alternative approaches should be explored and evaluated
