Google introduced Gemini 4 Hydrogen, a fast execution model for everyday coding and agentic workflows that complements the long-horizon reasoning models Gemini 4 Carbon and Argon. At its default high thinking level it scores 51 on the Artificial Analysis Intelligence Index versus Argon's 50, reaching 54 at the new xhigh setting; teams migrating from Gemini 3.8 Flash finish tasks 2.5 times faster, and Terminal-Bench 4.1 rises from 18.2% to 57%. Pricing is flat across its 1 million-token context at $1.50 per million input tokens and $7.50 per million output tokens.
