Poor chunking increases embedding and storage costs, reduces retrieval precision, and forces models to work with incomplete context, leading to hallucinations and inconsistent answers. Chunk size matters: large chunks preserve context but introduce noise, while small chunks improve precision but lack context and require stitching. Effective chunking strategies (fixed-length, sentence-level, header-based, semantic) should align with content structure and query patterns. Teams should measure chunking quality through retrieval precision, latency, answer quality, and user feedback, treating it as a core engineering decision rather than a preprocessing afterthought. ## Full article daily.dev links to this article rather than hosting it.
