About Chat2Graph

Chat2Graph is a Graph Native Agentic System designed to enhance key capabilities of agents—such as reasoning, planning, memory, knowledge, and tool collaboration—by leveraging the symbolic strengths of graph data structures, including relational modeling and interpretability. It also promotes the intelligence of graph databases, lowers the threshold for graph usage, accelerates content generation, and enables natural interaction with graphs. The project aims to deeply integrate graph computing technologies with artificial intelligence.

​
Use Chat2Graph

Open your browser and visit http://localhost:5010/ to start using Chat2Graph.

​
Register a Graph Database

To experience the full “chat with graph” capability, register a graph database instance in advance. Currently supported databases include Neo4j and TuGraph.
Start a Neo4j instance: 
docker pull neo4j:latest
docker run -d -p 7474:7474 -p 7687:7687 --name neo4j-server --env NEO4J_AUTH=none \
  --env NEO4J_PLUGINS='["apoc", "graph-data-science"]' neo4j:latest
Start a TuGraph instance: 
docker pull tugraph/tugraph-runtime-centos7:4.5.1
docker run -d -p 7070:7070 -p 7687:7687 -p 9090:9090 --name tugraph-server \
  tugraph/tugraph-runtime-centos7:latest lgraph_server -d run --enable_plugin true

​
Integrate Chat2Graph

Chat2Graph provides a clean and easy-to-use SDK API for customizing your own agentic systems. Configure the SiliconFlow model: 
SystemEnv.LLM_NAME="deepseek-ai/DeepSeek-V3"
SystemEnv.LLM_ENDPOINT="https://api.siliconflow.cn/v1"
SystemEnv.LLM_APIKEY="{your-siliconflow-api-key}"
Initialize the agent using a chat2graph.yml config file: 
chat2graph = AgenticService.load("app/core/sdk/chat2graph.yml")
Synchronous agent call: 
answer = chat2graph.execute("What is TuGraph ?").get_payload()
Asynchronous agent call: 
job = chat2graph.session().submit("What is TuGraph ?")
answer = job.wait().get_payload()
