Agentic AI from demo to production: what the evidence says about the architecture

Most agent pilots stall on the architecture around the model, not the model. What surveys, published incidents and reliability benchmarks show about tools, identity, retrieval, reversibility and measurement, and the six questions I ask before anything ships.

GraphRAG vs RAG: what the evidence actually says

GraphRAG wins on multi-hop and whole-corpus questions and loses on plain lookups, at a higher cost. What three studies show, how much weight each deserves, and a decision rule you can use.

Five questions before you build a knowledge graph for RAG

A GraphRAG business case, done the evidence-based way

The real cost of GraphRAG: indexing, queries and keeping the graph fresh
