AI Summary

Google is rolling out a Search upgrade that improves handling of complex, multi‑part queries, specific requests and typo‑laden questions. The enhancement relies on the newly released Gemini 4 Hydrogen model, which Google describes as its biggest improvement to Search to date. Unlike the frontier Gemini 4 Carbon and Argon models that excel at deep reasoning, Hydrogen is built for rapid execution across “agentic” workflows, where the AI performs multiple steps autonomously. The company announced the upgrade as part of its ongoing AI‑driven Search evolution.
