The new model focuses on rapid execution and multi-model workflows, positioning itself as a high-efficiency engine for developers and enterprises.
Google has introduced Gemini 4 Hydrogen, a model designed for speed and efficiency in everyday coding and agentic workflows, as first reported by the Google DeepMind Blog. According to the blog and Hacker News, Hydrogen is built for rapid execution, contrasting with frontier models like Gemini 4 Carbon and Gemini 4 Argon, which are reserved for deep, long-horizon reasoning.
Hydrogen is now available across the Gemini app, Google Search, the Gemini API, Google AI Studio, and for Gemini for business users and paid Google AI Pro and Ultra subscribers in Google Antigravity. The model features a 1 million-token context window, priced at $1.50 per million input tokens and $7.50 per million output tokens.
To optimize these workloads, Google is introducing Orchestrator in Google Antigravity. This tool dynamically switches between models—such as Carbon and Hydrogen—within a single session. On Terminal-Bench 4.0, Orchestrator achieved task success rates near those of Carbon while completing tasks 19% faster and using 24% less quota, per the Google DeepMind Blog.
Hydrogen also serves as a standalone upgrade from Gemini 3.8 Flash, finishing tasks 2.5 times faster at its high default setting. In early testing for data-heavy enterprise workflows, partners reported speeds 2x to 2.8x faster with token usage reductions between 12% and 23%. The model also demonstrates multimodal capabilities, synthesizing audio, video, and dense PDFs into cited reports, and supports real-time 3D coding via Geminisland.
