Prerequisites

This quickstart assumes that you're familiar with building applications with Python.

To complete this quickstart, ensure that your development environment meets the following requirements:

  • Python 3.9+

Install the Gemini API SDK

The Python SDK for the Gemini API is contained in the google-generativeai package. Install the dependency using pip:

pip install -q -U google-generativeai

Set up your API key

To use the Gemini API, you'll need an API key. If you don't already have one, create a key in Google AI Studio.

Get an API key from Google AI Studio

Then, configure your key.

It is strongly recommended that you do not check an API key into your version control system but assign it as an environment variable instead:

export API_KEY=<YOUR_API_KEY>

Import the library

Import and configure the Google Generative AI library.

import google.generativeai as genai
import os

genai.configure(api_key=os.environ["API_KEY"])

Make your first request

Use the generateContent method to generate text.

model = genai.GenerativeModel("gemini-1.5-flash")
response = model.generate_content("Write a story about a magic backpack.")
print(response.text)
text_generation.py

What's next

Now that you're set up to make requests to the Gemini API, you can use the full range of Gemini API capabilities to build your apps and workflows. To get started with Gemini API capabilities, see the following guides:

For in-depth documentation of Gemini API methods and request parameters, see the guides in the API reference.
