A new approach called Chunkless RAG, promoted by IBM, aims to improve retrieval-augmented generation by having AI agents navigate document structure like a human reader, rather than relying on fixed-size text chunks. This method uses tools like Docling to parse documents into structured representations, preserving elements like headings and tables. However, the author argues that this approach may overstate the problem of chunking, as real-world data is often messy and parsers can introduce their own errors, potentially leading to hallucinated structure. The core retrieval precision issue, the author contends, is more often a lack of lexical or semantic overlap between queries and relevant passages, which Chunkless RAG does not inherently solve and may even exacerbate by adding overhead.

IMPACT This approach may offer benefits for specific well-structured documents but faces challenges with messy real-world data and doesn't fundamentally solve core retrieval issues.
