Google DeepMind releases Gemini 4 Hydrogen
The company says Hydrogen is available across all tiers of Google AI Studio, the Gemini API, Gemini for business, the Gemini app and Google Search, and to paid AI Pro and Ultra subscribers in Google Antigravity. It has a 1 million-token context window priced flat at $1.50 per million input tokens and $7.50 per million output tokens. DeepMind also introduced Orchestrator in Antigravity, which switches between models such as Carbon and Hydrogen within a session.
Why it matters
A flat price across a 1 million-token context gives teams a predictable cost for long agentic and coding tasks, and Orchestrator lets them pair Hydrogen with frontier models in one session instead of choosing one model for the whole job.
