Google today launched Gemini 4 Hydrogen, a new AI model designed to replace its previous Flash model, offering faster performance and improved intelligence.

Hydrogen is priced flat across its entire 1 million-token context window at $1.50 per million input tokens and $7.50 per million output tokens.

Hydrogen surpasses Argon on the Artificial Analysis Intelligence Index at its default high thinking level (51 vs. 50), and reaches 54 at its highest xhigh thinking setting.

Hydrogen is built to stand on its own as a model for everyday work, or to pair with Carbon and Argon as the high-efficiency execution engine in multi-model workflows.

Hydrogen is designed to understand instructions better, stick to your tone, format, and rules, and keep following them through longer conversations.

Hydrogen reduces agentic overreach by up to 81 percent and reduces fabricated claims by more than five times compared with Gemini 3.8 Flash.

Hydrogen completes tasks approximately 2.5 times faster while improving its Terminal-Bench 4.1 score from 18.2% to 57%, according to Google’s evaluations.

Hydrogen is now available in Google Search for all users, and can be selected in the Gemini app’s model drop-down.

Hydrogen is also rolling out across Google AI Studio, Gemini API, Search and Gemini, with paid access in Antigravity and a new Orchestrator option.

Hydrogen is designed to handle links better, give more visual responses, and understand language more easily.

Hydrogen is better at following your guidance, calling the right tools, and getting you to a reliable output with less back-and-forth.

What this adds

Background

What's confirmed

• Rather than using a single model from start to finish, Orchestrator dynamically switches between models like Carbon and Hydrogen within the same session.
• Hydrogen surpasses Argon on the Artificial Analysis Intelligence Index at its default high thinking level (51 vs.
• Gemini 4 Hydrogen is priced flat across its entire 1 million-token context window at $1.50 per million input tokens and $7.50 per million output tokens.
• With Hydrogen, we’re also bringing Gemini 4 to everyone — for all tiers of Google AI Studio, the Gemini API, Gemini for business, the Gemini app, Google Search, and paid Google AI Pro and Ultra subscribers in Google Antigravity.
• Today, we’re introducing Gemini 4 Hydrogen, bringing cutting-edge intelligence to everyone — with speed and efficiency for everyday coding and agentic workflows.
• While our frontier models, Gemini 4 Carbon and Gemini 4 Argon, excel at deep, long-horizon reasoning on your hardest problems, Hydrogen is built for rapid execution across diverse agentic workflows.
• For workflows that require parallel agents, Carbon can act as the coordinator while Hydrogen can power worker and verifier agents to build and test changes simultaneously across isolated workspaces — helping teams ship complex projects faster without driving up token costs.
• Over on the Google Blog, the company announced Gemini 4 Hydrogen.

What's still developing

• Google is continuing its elemental AI naming scheme with the new Gemini 4 Hydrogen.
• The limits for Hydrogen are much more relaxed, with access beginning immediately.
• These names are less descriptive than the Pro/Flash monikers of earlier releases, but Hydrogen’s purpose is clear: It replaces the faster, more economical Flash models most people in Google’s ecosystem use.
• START FREE TRIAL (MONTHLY) START FREE TRIAL (ANNUAL) 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.
• What makes Hydrogen particularly interesting is that it isn’t just a watered-down “lite” model.
• 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 isn’t holding this one back behind a lengthy waitlist.
• 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.
• Hydrogen also builds clear comparisons using tables and visual breakdowns without missing key details.
• On Google Search, the Gemini 4 Hydrogen is designed to understand what you mean, even with multi-part questions, typos, or very specific requests.
• One thing that fascinates me about Gemini over other LLMs is that it's tailored strongly toward finding information and answering questions.
• Unlike its other element-named LLMs (such as Argon and Carbon), Hydrogen is not meant to be a bleeding-edge frontier model.
• Such is the case of Gemini 4 Hydrogen, a workhorse LLM that replaces Flash.
