+# LLM Wiki Pattern (Karpathy)
+
+> A method for building persistent, structured knowledge bases using LLM agents — compiled once, kept current, queried efficiently.
+
+## Tags
+`concept` `methodology` `knowledge-management` `2026-05-10`
+
+## Overview
+Andrej Karpathy proposed the "LLM Wiki" pattern as an alternative to RAG (Retrieval-Augmented Generation). Instead of searching raw documents on every query, an LLM agent incrementally builds and maintains a wiki of interlinked markdown pages.
+
+## Core Architecture
+
+### Three Layers
+1. **Raw Sources** (`raw/`) — Original documents, immutable. Never modified by the LLM.
+2. **Wiki** (`wiki/`) — Structured, interlinked markdown pages compiled by the LLM.
+3. **Schema** (`AGENTS.md`) — Rules, conventions, and workflows. The "operating system" of the wiki.
+
+### Workflows
+- **Ingest**: Drop source in `raw/` → LLM reads, extracts, creates/updates ~10-15 wiki pages per source
+- **Query**: Ask question → LLM reads `index.md` → drills into relevant pages → synthesizes answer with citations
+- **Lint**: Periodically audit wiki for contradictions, orphans, stale claims
+
+## Key Principles
+- One concept = one file
+- Cross-reference everything with `[[wikilinks]]`
+- The LLM owns the wiki directory; humans only edit `raw/` and the schema
+- Good answers get filed back into the wiki as new pages (compounding knowledge)
+- Works with any LLM that can read/write files (Claude Code, Codex, Cursor, local models via Ollama)
