In brief
Google's new Hydrogen model replaces Flash across its products with faster performance, fewer errors, and immediate broad access. Google released Gemini 4 Hydrogen, replacing its Flash model with 2.5 times faster performance and 5 times fewer fabricated claims. Originally reported by Ars Technica.
Google names new model Hydrogen
Google is rolling out Gemini 4 Hydrogen, continuing its elemental naming scheme. It replaces the faster, more economical Flash models most people in Google's ecosystem use.
Hydrogen launches with immediate broad access
Unlike recent Argon and Carbon releases, which started with cybersecurity researchers and paid subscribers, Hydrogen access begins immediately for everyone. It has replaced Gemini 3.8 Flash across Google's products.
Hydrogen is 2.5 times faster than Flash
Google claims Hydrogen represents major improvement over Flash. Even in high mode, it runs 2.5 times faster than Flash 3.8 and reduces fabricated claims by more than 5x. Code generation scores more than triple.
Hydrogen integrated into Google Search
Hydrogen is being integrated with Google Search, which Google says is the biggest update to its AI-powered search tools ever. It should better handle long, multipart questions with more visual elements in responses.
Access varies by subscription tier
Everyone gets Hydrogen in search, but access in the Gemini app and AI Studio is restricted.AI Pro and Ultra subscribers have it now.AI Plus and free users still use 3.5 Flash-Lite.
What it means
Google released Gemini 4 Hydrogen, replacing its Flash model with 2.5 times faster performance and 5 times fewer fabricated claims.
