Google has launched Hydrogen, the new main model in the Gemini 4 family, breaking the "smart, fast, cheap" impossible triangle. In the default high-thinking mode, its AA intelligence index reaches 51 points, surpassing the family's Argon, which focuses on deep reasoning; after maxing out the xhigh level, it rises to 54 points. The model has taken over core product lines such as Google Search, Google Sheets, and the Gemini App, supporting productivity features such as complex search decomposition, spreadsheet dynamic effect generation, and real-time 3D programming. The accompanying intelligent scheduler Orchestrator can dynamically coordinate with the flagship large model Carbon, reducing computing power consumption and improving speed while ensuring results. Hydrogen's hallucination rate is significantly reduced, it supports million-level input and output tokens, is affordably priced, ranks high on multiple professional Agent leaderboards, and significantly lowers the threshold for using high-cost-performance, high-performance models.
