A supplier was reinstated three days ago. The agent still treats them as suspended. The fix is not a faster refresh cycle.
ArchitectureWhy Search Alone Fails Your AI Agent
When the answer lives across three separate facts in three separate systems, similarity search can't get there. Here's what does.
TutorialInputLayer in 10 Minutes: From Docker to Your First Knowledge Graph
A hands-on tutorial to get InputLayer running and build your first knowledge graph with rules, recursive queries, and vector search.
EngineeringBenchmarks: 1,652x Faster Recursive Queries with Incremental Computation
One fact changes in a graph with 400,000 derived relationships. Full recompute: 11.3 seconds. InputLayer: 6.83 milliseconds. Here's how.
TutorialBuilding a Product Recommendation Engine with InputLayer
A step-by-step guide to building a recommendation engine that combines collaborative filtering, product relationships, and similarity by meaning - all in a single knowledge graph.
EngineeringWhy We Built InputLayer on Differential Dataflow
One fact changes. Two million derived conclusions exist. How many need to update? Usually a few hundred. Differential Dataflow finds exactly those, in milliseconds.
Use CaseFraud Detection Through Entity Chain Reasoning
A $50K wire to Alpha Corp looks clean. But Alpha is a subsidiary of Beta, which is 60% owned by Gamma, which is controlled by a sanctioned entity. Four hops deep.
ArchitectureWhen Similarity Is Not Enough
Some queries need the system to follow a chain of relationships to reach the answer. Here's how to recognize them and what to do about it.
