Today, we’re growing the Gemini 4 model series by introducing Gemini 4 Hydrogen. While Gemini 4 Carbon tackles your hardest problems, Hydrogen brings cutting-edge intelligence to everyone — with speed and efficiency for everyday coding and agentic workflows, surpassing Argon on the Artificial Analysis Intelligence Index at its default thinking level, at 2.5x the speed of Gemini 3.8 Flash, with tunable thinking levels built to work alongside Carbon in @antigravity. Watch how the 3D Medic Managed Agent app built in @GoogleAIStudio uses Gemini 4 Hydrogen to inspect your 3D files, catch errors, and patch them before export.

Ok this is a big deal. We’ve been testing Gemini 4 Hydrogen in early access with the Box AI Complex Work Eval, and it’s a serious jump for fast models. Hydrogen is 5 percentage points better in accuracy than Gemini 3.8 Flash. That alone would be a great boost in capability, but possibly more importantly it did the tasks in less than half the time with about 12% fewer tokens on a typical task. For this eval, we give the Box Agent Hydrogen as a model for a series of complex tasks that represent real world work with enterprise documents across finance, consulting, life sciences, and other industries. Hydrogen will be a great model for a lot of efficient but complex tasks across these fields. Gemini team is definitely cooking. Hydrogen will be rolling out in the Box AI Studio shortly so any…

SITUATION EXPLAINED: Google's new budget model Gemini 4 Hydrogen outscores its bigger Argon model, less than 4 weeks after Argon launched. • Hydrogen edged Argon 51 to 50 on the Artificial Analysis Intelligence Index, and hits 54 on a new "xhigh" thinking level • On Terminal-Bench 4.1, it scored 57% vs Gemini 3.8 Flash's 18.2%, and Google says hallucinations fell 5x • Hydrogen costs $1.50 per million input tokens and $7.50 per million output tokens, while Argon costs $2/$10 until Nov 30, then $4/$20 • Hydrogen is free for everyone in the Gemini app and Google Search, with a 1M-token context window • Claude Haiku 5.5, out since Oct 7, costs $0.10/$0.50 per million tokens, 15x less than Hydrogen for prompts under 100K @theojaffee: "If it surpasses Argon on the AA Intelligence Index, then…
