Google introduces Gemini 4 Hydrogen for faster everyday agent work

By IDAKIM Digital · Published November 13, 2026

A lower-cost Gemini option targets routine coding and execution, alongside model routing in Antigravity.

Google announced Gemini 4 Hydrogen on November 12, positioning it for everyday coding and agentic execution while reserving Carbon and Argon for more demanding reasoning. Access includes Google AI Studio and the Gemini API, with availability across Google’s business and consumer AI surfaces subject to their plans and rollouts. The announced API price is $1.50 per million input tokens and $7.50 per million output tokens, with a one-million-token context window. Antigravity also gains Orchestrator, which switches models during a task instead of committing every step to the same model. Google reports lower quota consumption and faster completion in its benchmark setup; those results are provider measurements. The combined release makes routing decisions part of the cost-performance evaluation, so a cheaper individual request does not establish a cheaper accepted change.

Why it matters

Compare completed tasks, review corrections and total token spend on a fixed repository sample. Check current access and pricing before changing production routing.
