Google on Thursday upgraded its search engine globally with the Gemini 4 Hydrogen model. The update is designed to provide more intuitive, visual and precise answers to user queries, according to the company.
The new model allows users to ask complex, multi-part questions in natural language. Google said the system can better understand user intent, highly specific requests and typos through deeper instruction following and tool calling.
To improve results, the search engine now uses an advanced reasoning capability to supercharge its query fan-out technique. This allows the system to conduct simultaneous queries across relevant subtopics, which Google said will connect users to a broader range of websites and helpful links they might not have discovered otherwise.
The update also introduces more visual and structured responses. According to the company, users will see more images, comparison tables and custom tools built into their search results.
Google stated that the richer language understanding capabilities are available in all languages currently supported by its AI models.
