Google rolls out Gemini 4 Hydrogen model to Search globally
Google has released its new Gemini 4 Hydrogen model which improves search answers for complicated questions and is now available to all users worldwide.
New model handles complex queries faster
The company states this update represents its biggest improvement to Search yet. Hydrogen completes tasks 2.5 times faster than the previous Gemini 3.8 Flash model while remaining smart enough to beat Gemini 4 Argon on one intelligence benchmark. Users can now ask questions with multiple parts or confusing typos and receive better answers across different languages supported by AI Mode.
Design focuses on speed and cost
Google explains that using the most powerful model is not always needed for every task. The new system is designed for fast execution across various agentic workflows where an AI carries out multiple steps on its own. It offers four thinking levels including a new extra-high tier to complete tasks faster with fewer output tokens.
Visual responses and tools expand
Search results will now include more images, structured responses, comparison tables, and custom tools as visual responses to queries. The model also improves the fan-out technique which breaks down single prompts into multiple subqueries to discover related websites. Hydrogen is available in Google AI Studio, the Gemini API, the Gemini App, and for paid Antigravity subscribers.
