Google has rolled out Gemini 4 Hydrogen, replacing Gemini 3.8 Flash across its product ecosystem with immediate general availability. The new model offers up to 2.5x speed improvements over Flash 3.8, reduces fabricated claims by over 5x, and shows strong gains in code generation benchmarks while competing closely with Google's premium Argon tier.
Background
Google has been using an elemental naming scheme for its Gemini family since 2026, with Hydrogen serving as the lightweight Fast-tier model. Previous elemental releases like Argon and Carbon were rolled out gradually with access restrictions before expanding.
