LLM Wiki Contribution
In early 2026, Karpathy posted about using LLMs to maintain personal knowledge bases via organized markdown files — no vector DB required. The post went viral on X within days.
Key insight from his post:
“Something I’ve been finding very useful recently is using LLMs to build personal knowledge bases for various topics of research interest.”
“I thought that I had to reach for fancy RAG, but the LLM has been pretty good about automaintaining index files and brief summaries of all documents.”
His scale: ~100 articles, ~500,000 words.
He intentionally left the prompt vague so others could customize it to their own projects.
