Google’s latest Search upgrade promises better answers to your most complicated questions

Google has upgraded Search with its new Gemini 4 Hydrogen model, which it calls its biggest Search improvement yet. Hydrogen is designed for fast execution across agentic workflows, completing tasks 2.5 times faster than Gemini 3.8 Flash while still outperforming the more powerful Gemini 4 Argon on the Artificial Analysis Intelligence Index at its default high thinking level. In Search, Hydrogen improves understanding of user intent, handles nuanced multi-part questions and confusing typos, offers more helpful links and visual responses (including images, structured responses, comparison tables and custom tools), and provides better answers across supported languages in AI Mode. Its reasoning also improves Search's fan-out technique, breaking a prompt into multiple subqueries to surface websites users might otherwise miss. Hydrogen offers four thinking levels (low, medium, high default, and a new extra-high tier) and can work alone on everyday tasks like coding, testing and verification, or be paired with Carbon and Argon in multi-model workflows. The update is rolling out to all Search users globally and is also coming to all tiers of Google's AI Studio, the Gemini API, the Gemini App, and paid AI Pro and Ultra subscribers in Google's Antigravity development platform.
