Google rolls out Gemini 4 Hydrogen to Search users worldwide

Google says it has rolled out Gemini 4 Hydrogen to Google Search users worldwide, describing it as the biggest model upgrade to Search so far. The company says the change is meant to give more helpful and intuitive answers to complex queries.
What the update changes for users
According to Google, Search can now interpret more nuanced and complicated questions and work out quickly what a user needs. Users can put multi-part questions in their own natural language, and the system is designed to cope with typos and highly specific requests about travel, shopping or hobbies.
Google also says the results themselves will look different. Answers are to include more visual content, including structured responses, comparison tables, images and custom tools, and Search is to link to a wider range of websites and tools.
Availability and scope
Google says Gemini 4 Hydrogen is available globally for all Search users and can be tried by visiting Google Search. The company says the visual and interactive features apply across all languages supported by AI Mode.
The announcement was published on the Google Blog under the name of Robby Stein, Vice President of Product for Google Search. The source of the information is therefore the company itself, and the claims about performance have not been independently tested in the material available.
