Gemini 4 Hydrogen is here with frontier-level speed for Search and the Gemini app

Google has been steadily rolling out its fourth-generation Gemini lineup over the past few months with heavyweights like Carbon and Argon, and today the company is bringing that same generation to the masses. In a new post on The Keyword, Google officially introduced Gemini 4 Hydrogen – a fast, high-efficiency model built to handle everyday workflows, coding, and agentic tasks without making you wait around for deep-reasoning compute.

What makes Hydrogen particularly interesting is that it isn’t just a watered-down “lite” model. According to Google, Hydrogen actually edges out the heavier Gemini 4 Argon on the Artificial Analysis Intelligence Index at its default thinking level, all while running 2.5 times faster than the older Gemini 3.8 Flash. And best of all, you don’t need an enterprise API key to try it out as it’s rolling out today across Google Search, the Gemini app, Google Sheets, and developer tools.

Better everyday help in the Gemini app and Google Search

For those of us using Gemini day in and day out to draft posts, organize research, or bounce ideas around, Hydrogen is designed to cut down on the back-and-forth. Google says the model is significantly better at sticking to formatting rules, tone, and multi-turn instructions on the first try. It also gets much smarter about pulling context from your connected apps like Gmail, Google Drive, Airtable, and Dropbox and calling the right tools automatically to finish multi-step tasks.

Over in Google Search, Hydrogen is now powering responses globally. Instead of forcing you to type rigid keywords, Search is getting better at parsing messy, multi-part questions and typos in a natural flow of thought. Google is also upgrading its query fan-out system under the hood, which should surface more visual, easy-to-scan answers alongside a wider variety of outbound web links.

Built for multi-model workflows and faster prototyping

On the developer and Workspace side of things, Hydrogen is pulling double duty as both a standalone workhorse and a sidekick to Google’s heavier models:

• Google Antigravity Orchestrator: A new Orchestrator feature dynamically switches between heavy models like Gemini 4 Carbon for big-picture planning and Hydrogen for rapid execution, cutting quota usage by 24% and speeding up tasks by nearly 20%.
• Upgraded Gemini in Google Sheets: Paid Google AI Pro, Ultra, and eligible Workspace users get Hydrogen inside Sheets today, turning financial data into interactive forecasting models over 30% faster than before.
• Massive context and thinking tiers: Hydrogen keeps a full 1 million-token input and output window (priced at $1.50 per million input tokens and $7.50 per million output tokens) and introduces four adjustable thinking levels—low, medium, high, and a new xhigh tier—so you only pay in time and tokens for the depth you actually need.

Where you can try Gemini 4 Hydrogen today

Google isn’t holding this one back behind a lengthy waitlist. Starting today, Gemini 4 Hydrogen is live in Google Search for all users, and you can select it in the Gemini app’s model drop-down (with free users getting routed to it automatically when a prompt calls for it).

If you’re a Google AI Pro or Ultra subscriber, you’ll also find it inside Google Sheets and Google Antigravity, while developers can jump straight into Google AI Studio, Android Studio, or the Gemini API right now. Give it a spin on a few multi-step prompts today, especially if you’re tired of waiting for heavier models to think through everyday tasks.
