Quick Use

Use it first, then decide how deep to go

This block should tell both the user and the agent what to copy, install, and apply first.

pip install autogen-agentchat autogen-ext
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

model = OpenAIChatCompletionClient(model="gpt-4o")
agent = AssistantAgent("assistant", model_client=model)

async def main():
    response = await agent.run(task="What is the capital of France?")
    print(response.messages[-1].content)
Intro

AutoGen is Microsoft's open-source framework for building multi-agent conversational AI.

Supports customizable conversation patterns, nested chats, and teachable agents. 56,000+ GitHub stars, the most popular multi-agent framework.

Best for: Building multi-agent systems where agents collaborate through conversation Works with: OpenAI, Anthropic, local models, Azure OpenAI

Core Concepts

Conversable Agents

Every agent can send and receive messages, forming conversations:

assistant = AssistantAgent("coder", model_client=model)
reviewer = AssistantAgent("reviewer", model_client=model,
    system_message="Review code for bugs and suggest improvements.")

Multi-Agent Teams

Agents work together in teams with defined conversation patterns:

from autogen_agentchat.teams import RoundRobinGroupChat
team = RoundRobinGroupChat([coder, reviewer, tester])
result = await team.run(task="Build a REST API for todos")

Code Execution

Agents can write and execute code in sandboxed environments.

Human-in-the-Loop

Insert human approval at any point in the agent conversation.

AutoGen Studio

Visual UI for building and testing multi-agent workflows without code.
