RAG chunking strategies impact LLM retrieval performance

By PulseAugur Editorial · [2 sources] ·

Optimizing retrieval-augmented generation (RAG) systems requires careful consideration of chunking strategies, as embedding quality directly impacts performance. For text, a chunk size between 256-512 tokens, with 10-20% overlap, is generally recommended to balance semantic completeness and context preservation. For structured data like tables, JSON, or XML, it's crucial to convert each row or element into a structured text snippet that retains hierarchical relationships and attribute context to ensure meaningful embeddings.

    RAG Chunking Best Practices for Production Systems

    <p>RAG chunking best practices start with understanding that your embedding quality depends entirely on how you split your source text. I've seen teams waste weeks tuning LLMs only to find their retrieval failed because chunks were too big, too small, or ripped context apart at t…
