Google GenAI SDK

The official, General Availability SDK for Python, JavaScript, Go, and Java: a unified interface to Google's Gemini 2.0+ models.

The Google GenAI SDK is your official, production-ready library for integrating Google's Gemini 2.0+ models directly into your applications. It provides a unified client across four major languages (Python, JavaScript/TypeScript, Go, and Java). This single design supports both the public Gemini Developer API and the enterprise-grade Gemini API on Vertex AI. Use the SDK to access core generative AI features: multi-turn chat, function calling, and efficient content generation. This is the recommended library, replacing all legacy Google AI SDKs for new Gemini development.
