Features

• Interpretable and Debuggable Knowledge: Graphs offer a human-navigable view of knowledge that can be queried, visualized, and updated.
• Fast, Low-cost, and Efficient: Designed to run at scale without heavy resource or cost requirements.
• Dynamic Data: Automatically generate and refine graphs to best fit your domain and ontology needs.
• Incremental Updates: Supports real-time updates as your data evolves.
• Intelligent Exploration: Leverages PageRank-based graph exploration for enhanced accuracy and dependability.
• Asynchronous & Typed: Fully asynchronous, with complete type support for robust and predictable workflows.

Fast GraphRAG is built to fit seamlessly into your retrieval pipeline, giving you the power of advanced RAG, without the overhead of building and designing agentic workflows.

Install

Install from PyPi (recommended)

pip install fast-graphrag

Install from source

# clone this repo first
cd fast-graphrag
poetry install

Quickstart

Set the OpenAI API key in the environment:

export OPENAI_API_KEY="sk-..."

Download a copy of A Christmas Carol by Charles Dickens:

curl https://raw.githubusercontent.com/circlemind-ai/fast-graphrag/refs/heads/main/mock_data.txt > ./book.txt

Use the Python snippet below:

from fast_graphrag import GraphRAG

DOMAIN = "Analyze this story and identify the characters. Focus on how they interact with each other, the locations they explore, and their relationships."

EXAMPLE_QUERIES = [
    "What is the significance of Christmas Eve in A Christmas Carol?",
    "How does the setting of Victorian London contribute to the story's themes?",
    "Describe the chain of events that leads to Scrooge's transformation.",
    "How does Dickens use the different spirits (Past, Present, and Future) to guide Scrooge?",
    "Why does Dickens choose to divide the story into \"staves\" rather than chapters?"
]

ENTITY_TYPES = ["Character", "Animal", "Place", "Object", "Activty", "Event"]

grag = GraphRAG(
    working_dir="./book_example",
    domain=DOMAIN,
    example_queries="\n".join(EXAMPLE_QUERIES),
    entity_types=ENTITY_TYPES
)

with open("./book.txt") as f:
    grag.insert(f.read())

print(grag.query("Who is Scrooge?").response)

The next time you initialize fast-graphrag from the same working directory, it will retain all the knowledge automatically.

Philosophy

Our mission is to increase the number of successful GenAI applications in the world. To do that, we build memory and data tools that enable LLM apps to leverage highly specialized retrieval pipelines without the complexity of setting up and maintaining agentic workflows.
