    Google Search gets a major upgrade with Gemini 4 Hydrogen

    Google announced that Gemini 4 Hydrogen, described as the biggest model upgrade to Search yet, is now available globally in Google Search for all users. The company says it improves understanding of intent for nuanced multi-part questions and typos, strengthens query fan-out and linking to surface more helpful sites, and delivers more visual responses such as images, comparison tables and custom tools, with richer language understanding across supported AI Mode languages.

    Why it matters: Useful for readers tracking how Google is integrating its Gemini models into core Search features and what changes users can expect.

    Faster Retrieval for Better, More Efficient RAG

    Apple researchers present amortized maximum inner product search (MIPS), training small neural networks offline on a fixed key database to learn the support function of the key set, which is convex and whose gradient returns the best-matching key. SupportNet learns per-cluster support functions to route queries more accurately than centroid-based routing, while KeyNet rewrites queries before a standard IVF index; on Natural Questions, SupportNet reached 95% routing recall about 1.9× faster than centroid routing, and KeyNet cut the time to 99% recall by up to ~8×. The work was presented at ICML 2026.
