Gemini API Libraries

This page provides information on downloading and installing the latest libraries for the Gemini API. If you're new to the Gemini API, get started with the API quickstart.

Important note about our new libraries

We've recently launched a new set of libraries that provide a more consistent and streamlined experience for accessing Google's generative AI models across different Google services.

Key Library Updates

We strongly encourage all users of the previous libraries to migrate to the new libraries. Despite the JavaScript/TypeScript library being in Preview, we still recommend that you start migrating, as long as you are comfortable with the caveats listed in the JavaScript/TypeScript section.

Python

You can install our Python library by running:

pip install google-genai

JavaScript and TypeScript

You can install our JavaScript and TypeScript library by running:

npm install @google/genai

The new JavaScript/TypeScript library is currently in preview, which means it may not be feature complete and that we may need to introduce breaking changes.

However, we highly recommend you start using the new SDK over the previous, soon-to-be deprecated version, as long as you are comfortable with these caveats. We are actively working towards a GA (General Availability) release for this library.

API keys in client-side applications

WARNING: No matter which library you're using, it is unsafe to insert your API key into client- side JavaScript or TypeScript code. Use server-side deployments for accessing Gemini API in production.

Go

You can install our Go library by running:

go get google.golang.org/genai
