Google Chrome Is Silently Installing a 4 GB AI Model on Your Device. Here’s How to Stop It

Google Chrome remains the world’s most popular browser, but it is facing increasing competition from a new generation of AI-powered browsers like Perplexity Comet and Dia. In an effort to stay ahead, Google has been integrating artificial intelligence into Chrome. However, a recent discovery has raised serious concerns about privacy and storage. Chrome is now quietly downloading a massive 4 GB AI model onto users’ devices without asking for permission. This Google Chrome AI model, known as Gemini Nano, is automatically installed on compatible hardware, and many users have no idea it is there.

What Is the Google Chrome AI Model and How Does It Install?

If you open your file manager and look for a folder named “OptGuideOnDeviceModel”, you may find a file called “weights.bin”. This file is roughly 4 GB in size and contains Gemini Nano, Google’s on-device AI model. Privacy expert Alexander Hanff discovered this behavior using macOS filesystem event logs, which track every file created or modified at the operating system level.

According to Hanff’s findings, on a freshly created Chrome profile that received zero human input, the entire 4 GB model downloaded in under 15 minutes while a tab was simply left open. Chrome does not ask for permission before installing the Google Chrome AI model. It automatically initiates the download once it determines that your hardware meets the requirements, even if you have never used any AI feature.

Why Is This a Problem for Users and the Environment?

This silent installation consumes significant storage space without user consent. Even worse, if you delete the file, Chrome re-downloads it the next time it runs. Hanff noted that “the user’s deletion is treated as a transient state to be corrected, not as a directive to be respected.”

Interestingly, the most visible AI feature in Chrome—the “AI Mode” pill in the address bar—does not use the local model at all. Instead, it sends your queries to Google Gemini servers. The on-device model powers less visible features like “Help me write” in text boxes and on-device scam detection. This raises the question: why download a 4 GB model for features most users never touch?

Beyond storage concerns, the environmental impact is staggering. Hanff estimates that if 500 million devices download this model, the bandwidth alone translates to roughly 30,000 tonnes of CO2 emissions. That is equivalent to around 6,500 cars running for an entire year—and that is just for the delivery, not actual usage.

How to Disable the Google Chrome AI Model Download

Google should make this download require user confirmation. Until then, you can stop it manually. Follow these steps to disable Google Chrome AI features:

  1. Open Chrome and type chrome://flags in the address bar.
  2. Search for “Enables optimization guide on device”.
  3. Change the setting from “Default” to “Disabled”.
  4. Restart Chrome for the change to take effect.

This method takes more steps than it should, but it effectively prevents Chrome from downloading the Gemini Nano model. For more tips on managing browser storage, check out our guide on clearing Chrome cache.

What Does This Mean for Chrome Users?

This incident highlights a growing trend of browsers adding features without user consent. As AI becomes more integrated into everyday software, users must remain vigilant. The Google Chrome AI model is just one example of how convenience can come at the cost of privacy and control.

If you value your storage space and want to avoid unnecessary data usage, disabling this feature is a smart move. For those concerned about privacy, consider exploring alternative browsers that prioritize transparency. Learn more about privacy-focused browsers that put you in control.

In the meantime, keep an eye on your system for unexpected files. Your device’s storage is yours, not Google’s server room. Take back control today.

Databricks wanted $1 billion. Investors offered $15 billion. Here’s what happened next.

Published

on

Databricks raises $5B

The leak that changed everything

It started with a single news article. Not a product launch, not a customer win — just a report from The Information that Databricks was raising money. That was enough to set off a chain reaction CEO Ali Ghodsi never anticipated.

“We wanted to raise $1 billion, but then The Information printed this article saying that Databricks is doing a big fundraise,” Ghodsi told TechCrunch. “We were heads down with our conference, and we were not actually at all focused on fundraising.”

The timing couldn’t have been worse. Databricks was in the middle of its annual user conference in June, and Ghodsi’s phone wouldn’t stop buzzing. “My phone blew up. It was like the worst timing for us because we were busy with our conference,” he recalled.

But here’s the thing about having too many investors pounding on your door — it’s a pretty good problem to have. What started as a modest $1 billion target quickly snowballed into something far bigger. “The interest level was just insane. Just from this select group of investors that we looked at, there was $15 billion of interest,” Ghodsi said.

From $1 billion to $5 billion: how the round grew

When you’ve got that much demand, telling longtime backers they can’t get in is a quick way to burn bridges. So Databricks made a pragmatic call: issue more stock. In July, the company announced it had closed a new round at a $188 billion valuation, though it kept the exact amount under wraps at the time.

On Thursday, the full picture emerged. Databricks raised $5 billion at a valuation that ticked up to a clean $190 billion. The round was led by Coatue, with participation from Blackstone, MGX, T. Rowe Price accounts, and newcomer Sixth Street Growth — the firm founded by former Goldman Sachs chief investment officer Alan Waxman. All told, about two dozen VCs got a piece of the deal.

Why investors were so eager

The answer is simple: Databricks looks like a sure bet. Ghodsi says the company has hit $7 billion in annualized run-rate revenue, growing at 80% and already cash-flow positive. Its core cloud data warehouse product alone generates $1.5 billion of that run-rate and is still expanding at 100% year-over-year.

Then there’s the AI angle. Lakebase, the company’s database for AI agents launched in June 2025, has already reached a $100 million revenue run-rate. And Genie, its AI chatbot for business analysis, is — in Ghodsi’s words — “insanely popular.”

Why raise more when the business is thriving?

That’s the obvious question. Databricks had already pulled in $20 billion over the past 20 months. But AI doesn’t come cheap.

“AI research is very expensive,” Ghodsi said, noting the company employs a 100-person AI research team. Databricks also has multi-billion dollar cloud commitments with all three major hyperscalers — AWS, Azure, and Google Cloud.

On top of that, Databricks is on an acquisition spree. This week it snapped up Electric, the company behind the lightweight Postgres database PGlite. In June it bought AI cybersecurity firm Panther, and in March it acquired two more startups. “We do a lot of M&A,” Ghodsi said simply.

The new math of mega-rounds

There was a time when a $1 billion raise was considered massive — a headline-grabbing feat that took months of courting investors. In today’s AI gold rush, that number barely moves the needle. Startups are walking out of the gate with billion-dollar seed rounds.

Databricks’ private fundraising has become something of a running joke in Silicon Valley. When the company announced this round last month, observers quipped online that it had raised so many times it was running out of letters of the alphabet to name the rounds.

What’s next for Databricks?

Ghodsi told CNBC he still wants to take the company public eventually. With this many investors on the cap table, all of whom will want an exit at some point, he doesn’t have much choice.

But for now, the focus is on investing in AI — and doing it out of the public eye. Given the expenses involved, staying private a while longer makes sense. And when you can command $15 billion in instant interest on your own terms, why rush?

Anti-surveillance clothing is getting cheaper, but don’t expect an invisibility cloak

anti-surveillance clothing

Privacy fashion moves from art school to the street

Anti-surveillance clothing is starting to look less like an art-school experiment and more like something you could actually wear outside. Shirts designed to confuse facial recognition systems now cost about as much as ordinary streetwear. But buying one won’t make you disappear.

Designers are using face-like prints, unusual cuts and infrared lights to interfere with computer vision, according to The Guardian. These techniques target specific weaknesses, so their success depends on what happens to be watching you.

How can clothing confuse a camera?

Adversarial clothing takes advantage of the shortcuts software uses to identify people and objects. Urban Privacy‘s Faception designs scatter fake faces across the fabric, giving an algorithm more visual noise to process.

Cap_able, meanwhile, uses knitted patterns created with AI. The company says versions of the YOLO object-detection system have mistaken its designs for animals or small figures instead of identifying the wearer as a person. It’s an amusing result, but fooling one model doesn’t guarantee the same trick will work elsewhere.

Infrared tricks for night vision

Urban Privacy’s experimental Urban Ghost coat tries a different approach. Infrared LEDs around its hood are intended to overwhelm compatible night-vision cameras. Regular cameras and other surveillance systems may remain completely unimpressed.

How affordable is privacy fashion?

Urban Privacy lists Faception Reloaded T-shirts from €35, sweatshirts from €59 and hoodies from €65. At those prices, anti-surveillance clothing isn’t reserved for wealthy privacy enthusiasts or gallery mannequins.

Cap_able remains considerably more expensive. Its knitted crop tops start at €560, while a hoodie costs €620. That puts the collection firmly in wearable-art territory, but the cheaper Urban Privacy garments show how quickly the idea is filtering down. You can now test an adversarial pattern without making your bank account unrecognizable too.

Why shouldn’t you trust it completely?

Controlled testing against one object-detection model can’t prove a garment will defeat facial recognition in public. Lighting and camera position can alter the result, while newer software may learn to ignore patterns that once caused trouble. Researcher Jennifer Bell also told The Guardian that these products haven’t undergone independent real-world testing.

That makes adversarial clothing more convincing as protest than protection. Wearing one makes a clear statement about surveillance and may inconvenience certain systems along the way. Just don’t treat a patterned hoodie as an anonymity switch. Until these garments face broader independent testing, assume the camera can still see you.

Google’s Gemini is about to let you fine-tune its voice. Here’s what’s coming

Published

Gemini voice customization

Google is handing you the mixing board for Gemini’s voice

For months, Google has been quietly pushing Gemini to sound less like a robot reading a script and more like, well, a person. The next step? Letting you dial in exactly how that person talks.

Fresh code pulled from the latest Google app beta (version 17.41.12) points to a new Gemini voice customization panel. Instead of picking from a handful of preset personalities, you’d get four separate sliders: Energy, Formality, Warmth, and Speed. Each one runs from Low to High (or Slow to Fast for speed).

That’s a meaningful departure from the current setup, where your choices are essentially limited to the voices Google cooked up for you.

What the new controls actually do

The feature hasn’t been announced yet, so we’re working from what’s visible in the code. Android Authority’s APK Insights team dug into the strings and found a dedicated “Customize” section tucked inside Gemini’s voice settings.

Here’s the breakdown of what you’d be able to adjust:

  • Energy: Low, Medium, High
  • Formality: Low, Medium, High
  • Warmth: Low, Medium, High
  • Speed: Slow, Normal, Fast

These aren’t meant to replace the existing voices. Rather, they’d layer on top of them. So you could pick a voice you like and then tweak its delivery to match your mood or use case — say, a brisk, formal tone for work queries and a slower, warmer one for casual chats.

The settings are expected to carry across both Gemini Live and the standard chat interface, which means you won’t have to reconfigure things depending on where you’re talking.

Why this matters after the Google I/O refresh

This discovery lands right after Google overhauled the voice picker following I/O. The old carousel interface is gone, replaced with a cleaner list. Two new voices — Flare and Glow — joined the lineup, bumping out Nova and Lyra.

The current roster now stands at ten voices: Ursa, Vega, Pegasus, Dipper, Eclipse, Capella, Orbit, Orion, Flare, and Glow.

Interesting detail: Google also stripped away the personality labels that used to describe each voice, things like “Calm” or “Bright.” Now you’re left to judge purely by ear. That move makes more sense in hindsight — if users are about to get granular controls, the preset descriptions become less relevant.

The interface is getting a facelift too

Alongside the voice changes, the update refreshes Gemini’s icons — slimmer, more modern takes on the microphone, camera, gallery, file upload, video, screen sharing, and Gemini Live buttons. These visual tweaks are rolling out via a server-side update alongside Gemini version 1.0.913571982.

Google isn’t the only one tuning voices

This push toward personalization fits a broader trend. At Google I/O, the company said regional dialects are on the roadmap for Gemini. Voice customization slots neatly into that effort to make AI feel less generic.

Apple is heading the same direction. Apple‘s iOS 27 gives Siri AI similar controls — Pace and Expressivity — and those preferences extend across Maps and Safari.

The subtext here is clear: the AI race isn’t just about what assistants can do anymore. It’s about how they sound while doing it. Tone, warmth, and cadence are becoming competitive battlegrounds.

What to expect next

None of this is official yet. Code in a beta doesn’t guarantee a public rollout, and Google could tweak the feature before it ships. But the trajectory is obvious.

If this lands as expected, you’ll soon be able to shape Gemini’s voice to fit your ear — not the other way around. For anyone who’s ever winced at a too-chipper assistant or struggled to follow a machine-gun-fast response, that’s a genuinely useful upgrade.

Keep an eye on the Google app beta updates in the coming weeks. And if you’re curious about where Gemini Live is headed, our Gemini Live features guide covers what’s already available. For more on the broader shift, check out how Siri’s new voice controls compare.
