Amazon Web Services (AWS) has announced the general availability of "Neptune--GraphLink," a new feature for Amazon Neptune that automatically synchronizes graph data with Large Language Models (LLMs) via a "Vector--Relational Bridge." Announced on July 18, 2026, the technology allows businesses to perform "Hybrid Semantic Search," combining the strengths of vector embeddings with the factual precision of graph structures. For the enterprise, this breakthrough reduces "Hallucination Rates" in customer--facing AI agents by providing a verifiable source of truth within the AWS ecosystem.
