SURREY, B.C. - Google has launched Gemini 4 Hydrogen, a faster everyday artificial intelligence model that is now powering Google Search for all users, the company announced on November 12, 2026.
Hydrogen is built for everyday coding and agentic work, the kind of AI that carries out multi-step tasks on a user’s behalf, such as writing code, running tests and pulling together research. It sits below Google’s frontier models, Gemini 4 Carbon and Gemini 4 Argon, which handle deep, long-horizon reasoning on the hardest problems. Hydrogen is the fast execution model that pairs with them.
On the Artificial Analysis Intelligence Index, a public benchmark of AI models, Hydrogen scores 51 against Argon’s 50 at its default high thinking level, and reaches 54 at its highest setting, called xhigh. Hydrogen has four thinking levels, low, medium, high and xhigh, so users wait and pay only for the reasoning depth a task needs.
Google says Hydrogen finishes tasks 2.5 times faster than Gemini 3.8 Flash at its default high setting, and more than triples its score on Terminal-Bench 4.1, a coding benchmark, to 57 percent from 18.2 percent. It is priced flat across its full 1 million-token context window at $1.50 per million input tokens and $7.50 per million output tokens. A token is the small chunk of text an AI model processes, and a 1 million-token window lets the model work with very large documents and codebases at once.
For ordinary users, the change most people will notice is in Search. Google says Hydrogen is significantly upgrading Search for all users globally, with better understanding of what a question really asks, even with typos or several parts, more visual responses and a wider range of relevant links through an upgraded query fan-out technique, which sends a question to more sources before answering.
In the Gemini app, Google says Hydrogen follows instructions more closely across multi-turn conversations, calls the right tools more often and produces email drafts, study guides and documents that need less back-and-forth. It is also rolling out in Google AI Studio for all tiers, the Gemini API, Gemini for business and Google Antigravity for paid Google AI Pro and Ultra subscribers. A new Orchestrator feature in Antigravity switches between Carbon and Hydrogen within a single session, using Carbon for planning and Hydrogen for execution.
For Surrey residents, the practical effect is in the tools many already use daily: searches that understand a rambling question better, a Gemini app that sticks closer to instructions, and cheaper, faster AI for local developers and small businesses building with Google’s AI Studio and API. The release carries no Canada-specific detail, and pricing is in U.S. dollars as published by Google.
