Google has updated Search with the Gemini 4 Hydrogen model, which is designed to handle complex queries, typos and multi-part questions more effectively, while showing more links and visual answers. The company says Hydrogen completes tasks 2.5 times faster than its previous fast model, Gemini 3.8 Flash. The update is rolling out to Search users worldwide. The model will also be available in Google AI Studio, the Gemini API, the Gemini app and the paid AI Pro and Ultra plans in the Antigravity development platform.
