Installing AG2

AG2 is available on PyPI as ag2. You can install it using pip, the Python package manager.

Tip

We recommend using a virtual environment for your project to keep your packages contained. See venv.

Run the following command to install AG2:

pip install "ag2[openai]"

This installs AG2 along with the openai package.

Note

From ag2 version 0.8: The OpenAI package, openai is not installed by default. You need to install it separately by adding the openai extra option.

Install with Your Preferred Model Provider(s)#

AG2 supports multiple AI model providers through optional dependency groups. Below are some examples of how to install AG2 with different model providers:

pip install "ag2[openai]"
pip install "ag2[gemini]"
pip install "ag2[anthropic,cohere,mistral]"

MacOS Tip

On MacOS, if you get a no matches found: error, it usually means you missed the double quotes enclosing the package name. Wrap it in quotes as shown in the example and you should be fine:

pip install "ag2[openai]"

Upgrading from autogen or pyautogen#

If you’ve been using autogen or pyautogen, upgrading is simple — no need to reinstall from scratch. ag2, autogen, and pyautogen are aliases for the same PyPI package.

👉 To upgrade, run:

pip install -U "autogen[openai]"

or

pip install -U "pyautogen[openai]"
