I Built a .NET 10 Knowledge Graph Builder (Inspired by Karpathy) Hi! Earlier this year, Andrej Karpathy tweeted about using LLMs as "knowledge compilers" — a mind-bending idea: instead of asking an LLM questions, feed it raw data (papers, code, images) and let it automatically build a structured, navigable knowledge base. No RAG. No vector databases. Just pure understanding compiled into a graph. Then I saw @socialwithaayan showcase graphify — a Python tool that does exactly this for codebases.
