Chat2Graph puts a multi-agent system on top of a graph database

Retrieval-augmented systems built on graph databases, often called GraphRAG, typically add a retrieval layer on top of the graph rather than treating the graph itself as where the reasoning happens. Ant Open Source's Chat2Graph instead builds a multi-agent system natively on top of a graph database, so agents query and act on the graph directly rather than through a separate retrieval step. The announcement is a short release post pointing to the project's GitHub code; a demo video accompanying the post has no accessible media file, only a preview thumbnail, so this explanation is limited to what the text and code release describe.
