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.
