💧 Google launches Gemini 4 Hydrogen, a cheap, fast model that edges out its own bigger sibling

Google has released Gemini 4 Hydrogen, a fast, low-cost Gemini 4 model built for everyday coding and agent work, rolling out globally in the Gemini app, Google Search, AI Studio and the Gemini API. Google says it beats Gemini 4 Argon on the Artificial Analysis Intelligence Index (51 vs. 50, or 54 at its top "xhigh" thinking level). It costs a flat $1.50 per million input tokens and $7.50 per million output across a 1M-token context, and a new Orchestrator in Antigravity mixes it with Carbon for big tasks.

⭐ Frontier-level smarts at a budget price make AI agents that run all day far cheaper, and free Gemini users get it too.
