The new AI model offers faster coding, automated workflows and a one-million-token context window, with access expanding across Google's developer, enterprise and consumer platforms.
Google has launched Gemini 4 Hydrogen, a new artificial intelligence model designed to support coding, research and business workflows, with improvements in processing speed and task execution. The model joins Google's Gemini 4 family alongside Gemini 4 Carbon and Gemini 4 Argon.
The company said Hydrogen is designed to perform tasks including writing code, identifying errors, running tests and analysing information. It can also work alongside other Gemini models, allowing different systems to handle tasks according to their complexity.
Alongside the model, Google has introduced Orchestrator within its Google Antigravity platform. The feature automatically selects between AI models depending on the requirements of a task, reducing the need for users to switch models manually.
For instance, Gemini 4 Carbon can handle complex reasoning tasks, while Hydrogen can undertake coding and testing activities.
According to Google, Orchestrator achieved task success rates close to Carbon on the Terminal-Bench 4.0 benchmark while consuming 24% less quota on average and completing tasks 19% faster.
The company also reported improvements in Hydrogen's performance compared with earlier Gemini models.
On the Artificial Analysis Intelligence Index, Hydrogen scored 51 at its default high-thinking setting, compared with 50 for Gemini 4 Argon. Its score increased to 54 when operating at the highest extra-high thinking level.
Google further stated that Hydrogen completes tasks 2.5 times faster than Gemini 3.8 Flash at its default high-thinking setting.
On Terminal-Bench 4.1, Hydrogen recorded a score of 57%, compared with 18.2% for Gemini 3.8 Flash, according to figures shared by the company.
The model supports a unified context window of up to one million tokens, covering both input and output. This enables it to process large amounts of information across documents, spreadsheets, charts, audio files and recorded videos.
Google said the capability can support activities such as generating reports, analysing datasets and producing structured business outputs.
Gemini 4 Hydrogen is being rolled out globally across Google's developer, enterprise and consumer products.
Developers can access the model through the Gemini API, Google AI Studio and the paid tier of Android Studio. Enterprise customers can use it through Gemini for business and eligible Google Sheets subscriptions.
The model is also available through the Gemini application and Google Search. Free Gemini users can access Hydrogen through automatic model selection when Google determines it is appropriate for a particular request.
Paid Google AI Pro and Ultra subscribers can access the model through Google Antigravity and Gemini in Sheets.
Google has priced Hydrogen at $1.50 per million input tokens and $7.50 per million output tokens.
The launch expands Google's AI offerings for software development and workplace productivity, with an emphasis on faster processing and automated task management.
