OpenAI’s API and models are fully supported in AG2. You will need an OpenAI account and to create an API key. See their website for further details.

​
Installation

From version 0.8: The OpenAI package, openai, is not installed by default, install it with the openai extra as shown below.
pip install ag2[openai]
If you have been using autogen or ag2, all you need to do is upgrade it using:
pip install -U autogen[openai]
or
pip install -U ag2[openai]
as autogen and ag2 are aliases for the same PyPI package.

​
LLM Configurations

See the LLM Configuration for further details on setting an creating an LLM configuration. The below example of an OAI_CONFIG_LIST shows how the OpenAI client class is used by specifying the api_type as openai. 
[
    {
        "api_type": "openai",
        "model": "o1",
        "api_key": "your OpenAI Key goes here",
    },
    {
        "api_type": "openai",
        "model": "gpt-4o-mini",
        "api_key": "your OpenAI Key goes here",
    },
    {
        "api_type": "openai",
        "model": "gpt-4o-mini",
        "api_key": "your OpenAI Key goes here",
    }
]
As an alternative to the api_key key and value in the config, you can set the environment variable OPENAI_API_KEY to your OpenAI key. Linux/Mac: 
export OPENAI_API_KEY="your_openai_api_key_here"
Windows: 
set OPENAI_API_KEY=your_openai_api_key_here
