AI Studio

Google released Gemini 4 Hydrogen, calling it its biggest model improvement to Search yet, designed for fast execution across multi-step agentic workflows rather than deep reasoning. It completes tasks 2.5x faster than the prior fast model Gemini 3.8 Flash and even beats the stronger Gemini 4 Argon on one broad intelligence benchmark. The update is rolling out to all Search users globally and also lands in AI Studio, the Gemini API, the Gemini App and the Antigravity developer platform.
