See also: Core Concepts\n\n- Token-based chunking: LLMs chunk based on token limits, not visual structure\n- DOM boundary heuristics: HTML structure influences but does not control chunking\n- Sentence vs semantic chunking: Chunks may split mid-sentence or combine multiple sentences\n- Overlap windows: Chunks overlap to preserve context, but overlap is not guaranteed\n- Truncation bias: Long sentences or paragraphs are truncated, losing information\nLLMs do not respect:\n\n- paragraphs\n- headings\n- visual sections\nThey chunk based on:\n\n- token limits\n- punctuation density\n- semantic similarity\n- transformer attention patterns\nIf a fact requires previous text, it is already broken.\n\nDesign every chunk to be self-contained. Never assume surrounding context will be preserved.\n\nTask: Select any existing webpage (yours or a competitor's). Copy three consecutive paragraphs. Split them into extraction-sized chunks as an LLM would, ignoring visual structure.\n\nConstraint: Each chunk must be token-limited (approximately 512 tokens). Split at semantic boundaries, not sentence boundaries.\n\nWhat success looks like: You produce a list of chunks where each chunk can be read in isolation without losing meaning. If a chunk requires previous context to be understood, you've identified a chunking failure.\n\nThis task is optional. No submission required. No validation. Use it to convert theory into applied thinking.\n\nNext: Module 2: Chunk Atomicity and Inference Cost\n\n\n\n---\n\nSource: https://nrlc.ai/en-us/docs/prechunking-seo/course/how-llms-chunk-content/\nPublisher: Neural Command LLC\nLicense: Editorial use with attribution\n" }, "structuredData": [ { "@context": "https://schema.org", "@graph": [ { "@type": "Organization", "@id": "https://nrlc.ai/#organization", "name": "Neural Command, LLC", "legalName": "Neural Command, LLC", "alternateName": [ "NRLC.ai", "Neural Command" ], "url": "https://nrlc.ai", "telephone": "+1 844-568-4624", "address": { "@type": "PostalAddress", "streetAddress": "1639 11th St suite 110-a", "addressLocality": "Santa Monica", "addressRegion": "CA", "postalCode": "90404", "addressCountry": "US" }, "logo": { "@type": "ImageObject", "url": "https://nrlc.ai/assets/images/nrlc-logo.png", "width": 43, "height": 43 }, "sameAs": [ "https://www.linkedin.com/company/neural-command/", "https://www.crunchbase.com/organization/neural-command", "https://g.co/kgs/EP6p5de" ], "description": "NRLC.ai designs semantic and knowledge architecture so organizations can be identified, related, evidenced, represented, and retrieved as reliable context for search engines, LLMs, agents, and other machine systems.
