I accidentally built Karpathy's LLM Wiki — with 5,420 memories, 6 AI agents, and a self-healing knowledge graph

The author describes unknowingly building a multi-agent cognitive engine called BrainDB, which mirrors Andrej Karpathy's LLM Wiki pattern with 5,420 memories and a self-healing knowledge graph. This system, developed on a homelab server, extends Karpathy's RAG-alternative by continuously refining and fact-checking its knowledge.
