Google is rolling out Gemini 4 Hydrogen to Search AI Mode users worldwide, adding a faster model intended to handle detailed prompts, multiple questions and misspellings more accurately. Hydrogen is designed for fast execution across tasks involving multiple steps. Hydrogen completes tasks 2.5 times faster than Gemini 3.8 Flash, Google's previous fast model. In AI Mode, Hydrogen is intended to follow instructions more closely and address each part of a request with greater precision. Users can write questions in their natural train of thought, including prompts with several parts or highly specific requests. Hydrogen improves Search's query fan-out, which breaks a prompt into multiple subqueries. This can surface websites related to a prompt that a user might otherwise miss. AI Mode responses can include more images, structured information, comparison tables and custom tools. The update also improves answers across the languages supported by AI Mode. Hydrogen is also coming to all tiers of Google AI Studio, the Gemini API and the Gemini app, as well as paid AI Pro and Ultra subscribers using Google's Antigravity development platform.
