Google Search gets a major upgrade with Gemini 4 Hydrogen

Google announced that Google Search is now globally powered by Gemini 4 Hydrogen, which the company calls the biggest model upgrade to Search to date. The upgrade delivers more helpful, visual, and intuitive responses through improved model capabilities. Search can better understand intent, handling nuanced multi-part questions, typos, and highly specific requests, and follows instructions and tool calls more precisely. Hydrogen's reasoning also supercharges the query fan-out technique, conducting simultaneous queries across subtopics to surface a broader range of useful links, including sites users might not have found before. Responses are more visual and easy to scan, featuring more images, structured responses, comparison tables, and custom tools, and language understanding is richer across all supported AI Mode languages. The article was written by Robby Stein, VP of Product, Google Search.
