Retrieval-Augmented Generation (RAG) pipelines are facing challenges related to chunking stability, as highlighted in a recent Reddit discussion. Users are reporting issues such as boundary drift, semantic fragmentation, inconsistent overlaps, context dilution, and segmentation differences across document formats. The discussion explored detection methods including boundary diffing, overlap uniformity scans, and adjacency cosine-distance deltas for early identification of these problems. Proposed solutions include improving extraction stability, aligning segmentation with document headings, standardizing overlap rules, and implementing re-chunking processes when content or formatting changes. The full discussion can be found on Reddit.
