Google has integrated its newest artificial intelligence model, Gemini 4 Hydrogen, into its AI Studio developer platform. The rollout follows a period of early access testing and the recent appearance of the model’s pricing in the company’s cloud billing catalogue.
Positioned as the successor to the Flash series, the Hydrogen model is designed for speed and lower operational costs compared to the company’s more powerful Gemini 4 Argon and Carbon models. It features introductory pricing of $0.75 for input and $3.75 for output, alongside a $0.0375 cache fee. While Google launched the high-end Gemini 4 Carbon model on Tuesday for paying users, its faster, cost-efficient variants have traditionally been provided to Gemini app users for free.
