Andrej Karpathy shares the "LLM Wiki" design pattern, where an AI agent actively maintains and organizes a user's knowledge base.

The "LLM Wiki" is a design pattern introduced by Andrej Karpathy to address the "memory rot" and organization challenges typical of second-brain systems. Instead of using standard Retrieval-Augmented Generation (RAG) to query a chaotic directory of notes, the pattern proposes a three-layer architecture: raw sources, a synthesized wiki of interlinked markdown files, and instructions for how the AI agent should maintain it. Under this pattern, the LLM acts as an active gardener of the wiki—synthesizing new info, identifying connections, and resolving contradictions—resulting in a compounding knowledge base.
