Google's next-generation Gemini frontier model emphasizing speed and efficiency for coding and agentic workflows.
Google introduces Gemini 4 Hydrogen, a fast and efficient model built for everyday coding and agentic workflows, complementing the deeper long-horizon reasoning of Gemini 4 Carbon and Argon. Hydrogen simultaneously rolls out across all tiers of Google AI Studio, the Gemini API, Gemini for business, the Gemini app, Google Search, and paid AI Pro/Ultra subscribers, marking the broad democratization of Gemini 4 capabilities.
Google DeepMind published the model card for Gemini 4 Hydrogen, positioning it as a frontier model tuned for speed and efficiency in everyday coding and agentic workflows. The card covers model information, training data, distribution, evaluations and intended-use limitations, and outlines CBRN and cybersecurity misuse mitigations, while the full safety report is still pending.
