Summary
Google says Gemini 4 Hydrogen is now available globally in Search. The update is designed to handle more complex questions and return responses with images, tables, links and custom tools.
Google says Gemini 4 Hydrogen is now available globally in Search, bringing updated AI capabilities for complex questions and more visual responses. The company says the model can better interpret multi-part requests, follow instructions and connect searches to a wider range of relevant websites.
How the Search update works
A central change is an expanded use of query fan-out: Search conducts simultaneous queries across relevant subtopics in response to a question. For a request with several requirements, this approach is intended to help find useful pages that a single, narrower query might miss. Google says the updated system can also handle typos and specific requests expressed in natural language.
The results may include more than text and links. Google says Search can provide images, structured information, comparison tables and custom tools tailored to a query. It gives travel, shopping and hobbies as examples of areas where people might ask about particular requirements.
Scope of the announcement
Google describes the rollout as global and says the capabilities are available to all Search users. It says responses are improved across all languages supported by AI Mode; that wording refers to the languages supported by the feature, rather than every language.
The practical change is an attempt to make Search handle a complicated request in fewer steps: interpret its parts, look across related subtopics and organise information in a format suited to the question. Google’s announcement describes these capabilities but does not provide numerical measurements of answer quality or link coverage.
