Google I/O has come and gone, and with it came an almost exclusive focus on AI. Part of the show was an announcement for Google Search that was so huge it was almost hard to believe: the AI-powered "Search Generative Experience (SGE)" that the company had been trialing for months is rolling out to everyone in the US. The feature, renamed "AI Overview," is here now, and it feels like the biggest change to Google Search ever. The top of many results (especially questions) are now dominated by an AI box that scrapes the web and gives you a sometimes-correct summary without needing to click on a single result.
AI Overview is a bit different from the SGE trials that were happening. First is that AI Overview is a lot faster than SGE. For some popular queries, it seems like Google is caching the AI answer, which should help with the high cost of running generative AI. For queries with cached overviews, you'll see the AI box load instantly, right along with the initial search results pop-in. SGE responses would come in word by word, like they are being typed by a person. When you aren't getting a cached result, you'll see a blank AI overview box that loads with the search page, which will say "searching" while it loads for a second or two. Other times, Google will try loading an AI Overview and fail, with the message "An AI overview is not available for this search." (As if anyone asked.)
