smolagents provides a flexible framework that allows you to use various language models from different providers.
This guide will show you how to use different model types with your agents.
smolagents supports several model types out of the box:
As explained in the Google Gemini API documentation (https://ai.google.dev/gemini-api/docs/openai), Google provides an OpenAI-compatible API for Gemini models, allowing you to use the OpenAIServerModel with Gemini models by setting the appropriate base URL.
First, install the required dependencies:
pip install smolagents[openai]
Then, get a Gemini API key and set it in your code:
GEMINI_API_KEY = <YOUR-GEMINI-API-KEY>
Now, you can initialize the Gemini model using the OpenAIServerModel class
and setting the api_base parameter to the Gemini API base URL:
from smolagents import OpenAIServerModel
model = OpenAIServerModel(
model_id="gemini-2.0-flash",
api_key=GEMINI_API_KEY,
# Google Gemini OpenAI-compatible API base URL
api_base="https://generativelanguage.googleapis.com/v1beta/openai/",
)
