Google Rebuilds Search Around AI With Gemini 3.5 Flash

Google is rebuilding its most important product around AI. At its I/O 2026 keynote the company made an AI-first interface the main way people use Search, replacing the familiar list of blue links with AI Mode, powered by a new model called Gemini 3.5 Flash. Executives called it the biggest change to Search since it launched. For a product that prints most of Alphabet's profit, that is a big bet.

For two years the question hanging over Google has been whether AI chatbots would eat its search business. ChatGPT and the rest trained users to ask a question and get an answer, not ten links. Google moved cautiously at first, bolting AI summaries on top of normal results. This goes further. Now the AI answer is the product, and the links live inside it.

Gemini 3.5 Flash is built for speed and huge request volume, tuned specifically for search. In AI Mode you get a generated summary, follow-up prompts, and tools embedded right in the results page, with links, images, and structured data woven into the response instead of sitting in a separate list. Standard web results are still reachable, Google says, just no longer the default view. The pitch is one fast, conversational page per query instead of a list you dig through.

Investors took it well. Alphabet traded around 373 dollars on Wednesday, up from a prior close near 369, holding close to the upper end of its 52-week range. Analysts stayed firmly positive, with an average price target in the low 430s. The read is simple. Google showing it can lead the AI search shift, rather than get run over by it, calms the biggest bear case on the stock.

The harder questions sit downstream. If users get their answer on Google's page, they click out less, and the open web that feeds Google its information gets fewer visits. Publishers, already squeezed, have been warning about exactly this. The ad model is the other unknown, since search ads were built around links and clicks, not AI summaries. Google has to grow a new ad format inside AI Mode without denting the cash machine. That transition is the thing to watch.

So this is Google defending its core by reinventing it. The technology question, whether it can build a good AI search, looks mostly answered. The business question, whether it can make AI search pay like the old one did, and what it does to everyone who lives on web traffic, is still open. Big move. Long shadow.
