cognee 0.1.11

Cognee - is a library for enriching LLM context with a semantic layer for better understanding and reasoning.

cognee

Deterministic LLMs Outputs for AI Engineers using graphs, LLMs and vector retrieval

Open-source framework for creating self-improving deterministic outputs for LLMs.

📦 Installation

With pip

pip install cognee

With poetry

poetry add cognee

💻 Usage

Setup

import os

os.environ["LLM_API_KEY"] = "YOUR OPENAI_API_KEY"

or

import cognee
cognee.config.llm_api_key = "YOUR_OPENAI_API_KEY"

To run the UI, run:

docker-compose up cognee

Then navigate to localhost:3000/wizard

You can also use Ollama or Anyscale as your LLM provider. For more info on local models check our docs

Run

import cognee

text = """Natural language processing (NLP) is an interdisciplinary
       subfield of computer science and information retrieval"""

cognee.add([text], "example_dataset") # Add a new piece of information

cognee.cognify() # Use LLMs and cognee to create knowledge

search_results = cognee.search("SIMILARITY", "computer science") # Query cognee for the knowledge

for result_text in search_results[0]:
    print(result_text)

Add alternative data types:

cognee.add("file://{absolute_path_to_file}", dataset_name)

Or

cognee.add("data://{absolute_path_to_directory}", dataset_name)

# This is useful if you have a directory with files organized in subdirectories.
# You can target which directory to add by providing dataset_name.
# Example:
#            root
#           /    \
#      reports  bills
#     /       \
#   2024     2023
#
# cognee.add("data://{absolute_path_to_root}", "reports.2024")
# This will add just directory 2024 under reports.

Vector retrieval, Graphs and LLMs

Cognee supports a variety of tools and services for different operations:

• Local Setup: By default, LanceDB runs locally with NetworkX and OpenAI.

• Vector Stores: Cognee supports Qdrant and Weaviate for vector storage.

• Language Models (LLMs): You can use either Anyscale or Ollama as your LLM provider.

• Graph Stores: In addition to LanceDB, Neo4j is also supported for graph storage.
