Google announced Gemini 4 Hydrogen on Nov 12, 2026. Hydrogen costs $1.50 per million input tokens, $0.075 per million cached tokens and $7.50 per million output tokens. That is a 25% discount now and will become a 75% discount after Dec 1, when the pricier Carbon and Argon models double. Google says Hydrogen is meant for everyday coding tasks and will power AI features in Google Search.
Why it matters
Developers get a cheaper, fast‑response model for routine code work and Search users see AI features powered by a lower‑cost engine.
