Larger Context Windows Don’t Fix RAG — So I Built a System That Does

📰 Towards Data Science

Learn why increasing context size in RAG systems doesn't improve accuracy and how to build a system that overcomes this limitation for aggregation tasks

advanced Published 13 Jun 2026
Action Steps
  1. Benchmark retrieval-based pipelines against a deterministic full-scan engine
  2. Analyze the impact of increasing context size on error detection
  3. Route computation queries away from RAG entirely
  4. Design and build a new system that addresses the limitations of RAG
  5. Test and evaluate the performance of the new system
Who Needs to Know This

Data scientists and AI engineers working with RAG systems can benefit from this knowledge to improve the accuracy of their models, especially for aggregation tasks

Key Insight

💡 Larger context windows don't fix RAG's limitations for aggregation tasks, a new approach is needed
