Google has begun rolling out Gemini 4 Hydrogen to Search worldwide, calling it the biggest model improvement to Search yet. The model is built for fast agentic workflows and completes tasks 2.5 times faster than Gemini 3.8 Flash. It improves understanding of complex, multi-part, and highly specific questions, including those with typos, so users can ask in natural language. Hydrogen strengthens query fan-out, breaking prompts into simultaneous subqueries to surface a wider range of relevant links. Responses in AI Mode become more visual, with more images, structured answers, comparison tables, and custom tools. Multilingual performance across supported AI Mode languages is also better. The update is available globally in Search and is also reaching Google AI Studio, the Gemini API, the Gemini App, and paid tiers of the Antigravity platform. Google positions Hydrogen as a balance of speed and capability for everyday use.
