Google Launches Gemini 4 Hydrogen AI Model

$GOOGL JUST LAUNCHED GEMINI 4 HYDROGEN. Google is rolling it out globally to all Search users, calling it the biggest model upgrade to Search yet. Hydrogen brings better understanding of complex, multi-part questions, discovers a wider range of relevant links and delivers richer visual responses, including comparison tables and custom tools. While Gemini 4 Carbon and Argon focus on deeper reasoning, Hydrogen is designed for faster, more efficient everyday coding and agentic workflows. Google says Hydrogen completes tasks 2.5x faster than Gemini 3.8 Flash, while its Terminal-Bench 4.1 score jumps from 18.2% to 57%. The model is also available in the Gemini app, Gemini API and AI Studio, with a 1M-token context window.
