X·low signal
A recording of Andrew Ng breaking down how to build agentic knowledge graphs from scratch — timestamped from a first working agent at 9:14 through how agent loops actually work at 33:11 — drew 1,116 likes and 164,785 views on X and is being called the best long-form material on graph engineering for agents. It is educational content rather than a product announcement, but the timing matters: agentic KG construction is exactly the retrieval layer that specialized search models like Toast 1 are competing with. Popularity metrics are from a single platform.
