Alphabet Inc. Class C (GOOGL.US) releases Gemini 4 Hydrogen: a daily coding model focused on "speed and economy"

Alphabet Inc. Class C (GOOGL.US) on Thursday released its latest artificial intelligence model, Gemini 4 Hydrogen, positioned as "fast and efficient for everyday coding and agentic workflows." "in real-world software development, teams rely on frontier models like Carbon and Argon for deep architectural judgment when designing systems or tracking down subtle bugs; but they still need a fast, rigorous execution model to write code, run tests, and verify changes," Alphabet Inc. Class C said in a post. "Hydrogen is positioned to serve both as a standalone model for everyday work and, paired with Carbon and Argon, as an efficient execution engine in multi-model workflows." Alphabet Inc. Class C added that under the default high thinking effort setting of the Artificial Analysis Intelligence Index, Hydrogen scored 51 points, surpassing the company's frontier model Argon (50 points), and reached 54 points under the highest xhigh thinking effort setting. Alphabet Inc. Class C said the model is priced at US$1.50 per 1 million input tokens and US$7.50 per 1 million output tokens. Alongside the release, Alphabet Inc. Class C said Hydrogen is rolling out globally across its developer, enterprise, and consumer surfaces. Developers can access it through the Gemini API in AI Studio and the paid tier of Android Studio, and paid Google AI Pro or Ultra subscribers can also use it. Enterprise users can access it through the API or the model dropdown, Google Antigravity, and Gemini in Google Sheets. Google AI Pro and Ultra subscribers can also use the model in the Gemini app, Google Search, and Gemini in Google Sheets. Alphabet Inc. Class C added that this makes the Gemini 4 model available to everyone.
