 Microsoft Agent Framework (MAF) is the enterprise‑ready successor to AutoGen. Microsoft Agent FrameworkAF in now available as a production-ready release: stable APIs, and a commitment to long-term support. Whether you're building a single assistant or orchestrating a fleet of specialized agents, Microsoft Agent Framework 1.0 gives you enterprise-grade multi-agent orchestration, multi-provider model support, and cross-runtime interoperability via A2A and MCP.

 Installation

AutoGen requires Python 3.10 or later.

bash
 Install AgentChat and OpenAI client from Extensions
pip install -U "autogen-agentchat" "autogen-ext[openai]"


The current stable version can be found in the releases. If you are upgrading from AutoGen v0.2, please refer to the Migration Guide for detailed instructions on how to update your code and configurations.

bash
 Install AutoGen Studio for no-code GUI
pip install -U "autogenstudio"


 Quickstart

The following samples call OpenAI API, so you first need to create an account and export your key as export OPENAI_API_KEY="sk-...".

 Hello World

Create an assistant agent using OpenAI's GPT-4o model. See other supported models.

python
import asyncio
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

async def main() - None:
    model_client = OpenAIChatCompletionClient(model="gpt-4.1")
    agent = AssistantAgent("assistant", model_client=model_client)
    print(await agent.run(task="Say 'Hello World!'"))
    await model_client.close()

asyncio.run(main())


 MCP Server

Create a web browsing assistant agent that uses the Playwright MCP server.

python
 First run npm install -g @playwright/mcp@latest to install the MCP server.
import asyncio
from autogen_agentchat.agents import AssistantAgent
from autogen_agentc
