A framework for orchestrating applications powered by autonomous AI agents and LLMs.

Why Gwenflow?

Gwenflow, a framework designed by Gwenlake, streamlines the creation of customized, production-ready applications built around Agents and Large Language Models (LLMs). It provides developers with the tools necessary to integrate LLMs and Agents, enabling efficient and scalable solutions tailored to specific business or user needs.

Installation

Install from PyPI:

pip install gwenflow

Install from the main branch to try the newest features:

# install from Github
pip install -U git+https://github.com/gwenlake/gwenflow.git@main

Usage

Load your OpenAI api key from an environment variable:

import os
from gwenflow import ChatOpenAI

llm = ChatOpenAI(
    api_key=os.environ.get("OPENAI_API_KEY"),  # This is the default and can be omitted
)

or load your api key from a local .env file:

import os
import dotenv
from gwenflow import ChatOpenAI

dotenv.load_dotenv(override=True)  # load you api key from .env

llm = ChatOpenAI()

Chat

import os
from gwenflow import ChatOpenAI

dotenv.load_dotenv(override=True)  # load you api key from .env

messages = [
    {
        "role": "user",
        "content": "Describe Argentina in one sentence."
    }
]

llm = ChatOpenAI(model="gpt-4o-mini")
print(llm.invoke(messages=messages))

Agents
