Google Search goes fully AI-generated with Gemini 3.5 Flash
Every Google search query now returns an AI-written answer by default — and there is no permanent opt-out.

- From 10 July 2026, all Google searches default to an AI-generated prose answer powered by Gemini 3.5 Flash — not just the opt-in AI Mode tab.
- The traditional ranked blue links still exist but are now secondary, appearing below the AI answer rather than leading the page.
- There is no permanent opt-out, though selecting the "Web" filter tab after a search returns a more traditional link-based view.
- UK publishers are already seeing click-through rates on top search positions fall by as much as 59% when AI answers appear, according to Sistrix data.
Google rewrites the rules of search — permanently
Google completed the most sweeping transformation of its search product in 27 years on 10 July 2026. Every query submitted to Google Search now returns an AI-generated prose answer as its primary result, synthesised in real time by Gemini 3.5 Flash, the company's newest and fastest inference model. The familiar ranked list of ten blue links — the backbone of the web since 1998 — has been pushed below the fold, subordinate to the AI answer that now greets every user, on every device, globally.
This is not the opt-in AI Mode tab that Google introduced last year. As of 10 July, the AI answer is the default for all searches across all of Google's surfaces, with no opt-out toggle available.
What you actually see now
When you type a query into Google today, Gemini 3.5 Flash generates a prose response synthesised from multiple web sources. Those sources appear as inline citations within the text — like footnotes in an essay — rather than as a ranked list beneath your search box. The traditional ranked links remain on the page, but they are secondary. If you want to skip the AI answer entirely and go straight to a list of links, your quickest option is to click the Web filter tab that appears beneath the search bar. That is as close to the old experience as Google currently offers.
The road to 10 July
The rollout completed a transition Google announced publicly at its Google I/O developer conference on 19 May 2026. At that event, Liz Reid, Google's Vice President of Search, described the changes as "the biggest upgrade to our iconic search box in over 25 years."
The I/O announcements included upgrading Search with Gemini 3.5 Flash as the new default model in AI Mode, a completely reimagined search box with multimodal inputs — text, images, files, videos and Chrome tabs — and new generative UI capabilities built on a framework called Google Antigravity, which can assemble interactive dashboards, calculators and simulations on the fly for specific query types.
AI Mode, which launched as an opt-in feature, had already surpassed one billion monthly users before the full rollout, with queries more than doubling every quarter since launch, according to Google. The company also reported that total search queries reached an all-time high last quarter.
In the UK specifically, AI Overviews arrived in July 2025, shortly after their US debut in May 2025. AI Mode followed at the same time, offering what Google described as a more conversational, ChatGPT-style experience. The 10 July change collapses that distinction: there is no longer a separate AI Mode. There is only Search, and Search is AI.
What makes Gemini 3.5 Flash different
Google describes Gemini 3.5 Flash as four times faster than comparable frontier models in output tokens per second. Despite being the "lighter" model in the Gemini 3.5 family, Google says it outperforms the older Gemini 3.1 Pro on a range of demanding benchmarks, including:
- GPQA Diamond: 90.4% — a benchmark testing PhD-level scientific reasoning
- SWE-bench Verified: 78% — a coding evaluation
- MMMU-Pro: 81.2% — multimodal understanding tasks
- Terminal-Bench 2.1: 76.2% — agentic coding capability
The model supports a context window of up to one million tokens. To give a sense of the scale at which Google is now running these systems, CEO Sundar Pichai revealed the company is processing more than 3.2 quadrillion tokens per month — compared with 480 trillion tokens per month at I/O 2025.
Google Antigravity, the generative UI framework running alongside Flash, can produce custom interactive layouts in real time. Google says these capabilities — including simulations and visual dashboards — will be available to all users in Search this summer, free of charge.
What it costs — and what remains unclear
For consumers, AI-generated search results remain free. Google AI Plus is priced at $7.99 per month and Google AI Pro at $19.99 per month in the US; Google AI Ultra was cut from $249.99 to $99.99 per month. UK sterling pricing for these subscription tiers has not been confirmed. The free Gemini tier now includes Gemini 3.5 Flash as its default model, along with a daily allotment of Gemini 3.1 Pro, up to five Deep Research reports per month, and Gemini Live voice mode.
Developers accessing Gemini 3.5 Flash via the API pay $1.50 per million input tokens and $9.00 per million output tokens — roughly 25% cheaper than the older Gemini 3.1 Pro, which was priced at $2.00 and $12.00 respectively.
What it means for UK users and publishers
The trust gap is significant. Only 18% of UK users currently believe AI search results are reliable, rising to 21% among 16 to 24 year olds, according to survey data cited ahead of the rollout. That means a large majority of UK users are now receiving AI-generated answers they consider untrustworthy as their primary search experience — whether they want them or not.
For UK news publishers and websites, the picture is bleak. According to Sistrix analysis reported by Press Gazette in May 2026, when an AI Overview appears on a results page, the click-through rate to the top organic result drops from 27% to just 11% — a 59% decline. A separate Ahrefs study published in February 2026 found AI Overviews correlate with a 58% reduction in click-through rates for top-ranking pages, nearly double the 34.5% decline documented in April 2025. With AI answers now appearing on all queries rather than roughly one in three, those numbers are set to worsen considerably.
Google is offering a free Gemini upgrade for UK students aged 18 and over through July 2026, covering access to its latest AI model for exam preparation, writing assistance and research.
What's next
Attention in the coming days will turn to Gemini 3.5 Pro, the more powerful sibling to Flash. Third-party sources have reported a possible launch around 17 July, with an alleged two-million-token context window and advanced reasoning capabilities — but as of 13 July, Google has made no official announcement confirming the date, the specifications, or pricing. The model slipped from a June target after Google DeepMind opted to discard its initial foundation and rebuild it from scratch. Sundar Pichai acknowledged the delay at I/O, telling developers: "Give us until next month to get it to you." That month has now passed.
Why it matters
For everyday UK users, this is the most significant change to how the internet's front door works in nearly three decades — and it arrived without a meaningful choice to refuse it. Reliability is a genuine concern: only 18% of UK users currently believe AI search results are trustworthy, according to survey data, which means millions of people are now receiving AI-synthesised answers they did not ask for and largely do not trust. For UK publishers and media outlets, the stakes are existential: Sistrix data shows a 59% collapse in click-through rates when an AI answer appears above organic results, and that was before full deployment. The shift to Gemini 3.5 Flash across all queries, not merely the AI Mode tab, means those traffic losses are no longer the exception — they are the rule.
