In Part 1, we explored why GraphRAG matters. Now let's build a minimum viable GraphRAG with three extraction modes:

Your RAG system is great at "needle" questions: retrieve a few relevant chunks and synthesise an answer. It struggles with two common query types:

I keep seeing the same failure mode in "AI-powered" systems: LLMs are being asked to do jobs we already solved decades ago - badly, probabilistically, and without guarantees.
This isn't cutting edge....

Most “chat with your data” systems make the same mistake: they treat an LLM as if it were a database.
They shove rows into context, embed chunks, or pick “representative samples” and hope the model...

Here's the mistake everyone makes with document summarization: they extract the text and send as much as fits to an LLM. The LLM does its best with whatever landed in context, structure gets...

Series: Local LLMs for Data - Part 1 of 2
Here's the mistake everyone makes: they try to feed their CSV into an LLM. Don't. LLMs should generate queries, not consume data.
You've got a 500MB CSV file...

I'm a .NET developer. When I started building LLM-powered systems, everyone pointed me toward LangChain. "It's the standard," they said. "All the examples use it." And they were right - if you're in...
