Watch Desk Update What changedGoogle says Gemini 4 Hydrogen completes tasks 2.5 times faster than its previous fast model, Gemini 3.8 Flash. TechCrunch reports that Hydrogen now powers the AI Mode search improvements already covered in this thread, with Google saying it can better handle complicated, multi-part questions and typos.
Google also claims Hydrogen beats the more powerful Gemini 4 Argon on one broad intelligence benchmark, the Artificial Analysis Intelligence Index, at its default high-thinking level. That is a result on one benchmark, not a general finding that Hydrogen is the stronger model.
The change is rolling out to all Search users globally, according to TechCrunch. Hydrogen is also coming to Google AI Studio, the Gemini API, the Gemini app and paid AI Pro and Ultra subscribers using Antigravity.

The model is available in Google Search, the Gemini app, Google AI Studio, the Gemini API and Gemini for business. Google Antigravity access is available to AI Pro and Ultra subscribers, according to the report.
