Google has released Gemini 4 Hydrogen, a faster model for everyday coding and agentic workflows, across the Gemini API, AI Studio, the Gemini app and other Google products. It is priced at $1.50 per million input tokens and $7.50 per million output tokens across a 1 million-token context window.

Google has introduced Gemini 4 Hydrogen alongside its frontier models, Gemini 4 Carbon and Gemini 4 Argon. Hydrogen scores 51 on the Artificial Analysis Intelligence Index at its default high thinking level, ahead of Argon's 50, and reaches 54 at the new xhigh setting. Its pricing is flat across the full context window.

Google also introduced Orchestrator in Google Antigravity, which switches between Carbon and Hydrogen within one session. On Terminal-Bench 4.0, Orchestrator reached near-Carbon task success rates while using 24% less quota and finishing 19% faster on average. For parallel work, Carbon can coordinate while Hydrogen powers worker and verifier agents in isolated workspaces.

Compared with Gemini 3.8 Flash, Google says Hydrogen finishes tasks 2.5 times faster at its high setting and scores 57% on Terminal-Bench 4.1, up from 18.2%. Developers can use it through the Gemini API in AI Studio and the paid tier in Android Studio, and paid Google AI Pro and Ultra subscribers can use it in Google Antigravity.

## Why it matters if you build agents

Agent builders can send fast execution steps to Hydrogen and keep Carbon or Argon for harder reasoning, which may help control token costs in multi-model setups. Flat pricing across the 1 million-token window makes long-context costs simpler to estimate. Teams should still test their own tool permission and safety behavior, since the reported gains come from Google's evaluations.
