Open-Source LLM Wiki Emerges as Persistent Knowledge Graph Alternative to Traditional RAG

An open-source alternative to retrieval-augmented generation is gaining traction: LLM Wiki systems that build persistent, interconnected knowledge bases instead of retrieving and synthesizing documents on demand. The approach, pioneered conceptually by Andrej Karpathy in April 2026, represents a fundamental shift in how AI systems handle knowledge—from stateless retrieval to persistent, evolving repositories that improve with every new source document.
