What is Gemini Developer API?
Gemini Developer API is Google's developer platform for building applications on top of its Gemini family of models, along with image (Imagen), video (Veo), and open Gemma models. Developers get an API key, call the models from their own apps through the Gemini API, and use Google AI Studio to explore models, test prompts, and turn ideas into code. The site also covers on-device options such as Google AI Edge and Gemini Nano on Android and Chrome's built-in web AI APIs.
In practice you can add AI features to an app with a single API call, evaluate and prototype prompts in AI Studio, and get coding help through integrations with Android Studio, VS Code, JetBrains IDEs, Colab, Firebase, Google Cloud, and Chrome DevTools. Teams that need full control can customize Gemma open models with their own data, and the docs cover batch processing, context caching, and responsible AI tooling.
