Google's Gemini 4 Hydrogen is rolling out in the Gemini app and Search. Here's what changes for Android users.
Google announced Gemini 4 Hydrogen on November 12. It replaces the Flash line as Google's fast, everyday AI model.
Hydrogen sits under Everyday help in the model picker. Free users get it through automatic model selection when it fits the prompt.
Google calls it the biggest model upgrade to Search yet. It handles long, messy questions and adds more tables and images in AI Mode.
Hydrogen scores 51 on the Artificial Analysis index, one point above Gemini 4 Argon. Google says it is 2.5x faster than 3.8 Flash.
Developers pay $1.50 and $7.50 per million tokens. For free Android users, the Gemini app and Search just got smarter at no cost.
