Google’s new Gemini model is better at understanding complicated questions

Google says its new Gemini 4 Hydrogen model can give more helpful answers to complex questions, including ones with multiple parts, hard-to-understand typos, or highly specific requests, by breaking them down and addressing each part. It is available starting today in Search, the Gemini app, all tiers of Google AI Studio, the Gemini API, Gemini for business, and Google Antigravity for AI Pro and Ultra subscribers, and is now the default model in AI Mode. Google says it delivers significant leaps in speed and intelligence compared to Gemini Flash 3.8 and matches or outperforms competing models like Claude Sonnet 5.5 and GPT-6.1 Terra.
