RAG Improves with Semantic Chunking
Developers are shifting from fixed-size chunking to semantic-aware indexing in RAG systems, reducing re-ingestion costs and improving retrieval accuracy.
Why now
This shift is crucial as RAG systems scale, addressing inefficiencies and improving the cost-per-query economics for enterprises.
Key signals
Implementing content-defined chunking can reduce re-ingestion costs by over 90%.
Documents should be split by semantic meaning rather than arbitrary character counts.
