Karpathy's LLM Wiki nailed something. LLMs are perfect for the bookkeeping that kills knowledge bases. Updating cross-references, flagging contradictions, keeping pages consistent - that's what they're good at. Humans curate, LLMs maintain. The wiki compounds because maintenance cost drops to zero.
I've been running a version of this for months. One thing kept breaking.
LLM Wiki has three layers: raw sources (immutable), the wiki (LLM-maintained), and a schema (configuration). The schema tells the LLM how to structure the wiki.
