Google Adds Gemini 4 Hydrogen to Android Studio and Gemini for Business
The coding model is also available in Google AI Studio and to paid AI Pro and Ultra subscribers through Google Antigravity.

Google made Gemini 4 Hydrogen available Thursday, Nov. 12, across developer and business products, adding Android Studio and Gemini for business to the model’s coding rollout.
The release confirms availability in Google AI Studio and through Google Antigravity, while listing Android Studio and Gemini for business as additional destinations. Paid Google AI Pro and Ultra subscribers can use Hydrogen through Antigravity. Developers can also build with the Gemini API.
Hydrogen is designed for repository coding, debugging and interactive web development. It accepts text, image, audio and video inputs, offers four configurable thinking levels, and can operate alone or alongside Gemini 4 Carbon and Gemini 4 Argon.
The model’s context window can reach 1 million tokens across input and output. Its default synchronous output limit is 64,000 tokens, while background decoding supports up to 1 million tokens.
The developer release follows Google’s worldwide Gemini 4 Hydrogen rollout in Search AI Mode, which had already outlined plans to bring the model to Google AI Studio, the Gemini API and Antigravity.
