When to use
Optimised for: relationship modeling + reasoning + governance over pure vector
Anti-fit: not for purely-vector or simple-RAG use cases (graph adds setup cost)
Pros & cons
Pros
Pre-built knowledge graph of the web (KGoW) — you don't build the graph, you query someone else's; saves enormous extraction cost.
Cons
Quality is bounded by Diffbot's extraction; no schema control; not appropriate for proprietary internal data.
Claims & capabilities
10B+ entities and 1T+ structured facts crawled from public web; 81% accuracy on FreshQA (Google factuality benchmark) — beats ChatGPT and Gemini; 70.36% MMLU-Pro; customers include Cisco, DuckDuckGo, Snapchat, Adobe, AOL, eBay, Microsoft
