Google released Gemini 4 Hydrogen, the cheapest member of the Gemini 4 family, at $1.50/M input and $7.50/M output tokens, only about 25% below its larger siblings. Carbon and Argon share identical pricing and are both scheduled to double on December 1, 2026, with Google distinguishing Argon by lower token spend per turn, leaving the pricing scheme notably confusing.
