Introducing Gemini 4 Hydrogen
Hydrogen costs $1.50 per million input tokens and $7.50 per million output tokens across its full million-token context window.
Google says the model is rolling out globally across the Gemini API, Gemini app, Search and enterprise products, with subscription requirements on some surfaces. At its default high thinking setting, Hydrogen scores 51 on the Artificial Analysis Intelligence Index against Argon’s 50, according to the announcement. Google also introduces Antigravity’s Orchestrator, which switches models within a session and reportedly approaches Carbon’s Terminal-Bench 4.0 success rate while using 24% less quota and finishing 19% faster. Four thinking levels let users adjust reasoning depth, latency and cost.
