RAG Just Became a Trainable Neural Graph (WikiFM)

Are your agentic RAG pipelines bottlenecked by sparse knowledge graphs that ruthlessly shred dense contextual semantics into rigid triples? In this deep dive, we unpack the Wiki Foundation Model (WFM), a novel architecture that abandons traditional sparse graphs for native "LLM Wikis," directly coupling discrete topological entities with continuous document embeddings in a unified geometric space. We will break down the underlying mathematics of how WFM cures catastrophic Softmax variance de
