Google finally explains why Android AICore keeps eating your storage — and it actually makes a lot of sense

If you’ve ever glanced at your Android phone’s storage breakdown and done a double-take at how much space AICore is consuming, you’re not alone. It’s one of those things that’s easy to notice and hard to explain, and for a while, Google wasn’t offering much clarity on it. That’s changed now, and the explanation turns out to be more sensible than the mystery surrounding it suggested.

AICore is the on-device AI backbone that powers a growing list of features on Android 14 and above — smart replies in WhatsApp, scam detection in messages, real-time transcription, grammar correction, audio summarization, and more. It runs Gemini Nano locally on supported hardware, which means your data stays on your device, the features work without an internet connection, and there’s no latency from bouncing a request off a remote server. The trade-off, as anyone who’s installed a multi-gigabyte model knows, is storage.

The storage spike has a simple explanation

Google has now published a support article addressing the one thing that confused people most: why AICore’s storage footprint sometimes balloons unexpectedly. The answer is that when a new version of Gemini Nano becomes available, AICore holds both the old and the new versions simultaneously for up to 3 days before clearing the original version.

It’s a precautionary measure. If the new model version encounters problems after installation, your phone can instantly revert to the previous version rather than re-download gigabytes of model data from scratch. It’s the kind of sensible engineering decision that’s obvious in hindsight, but Google probably should have communicated it sooner, given how much confusion it’s caused.

Why this matters for your Android storage management

For users concerned about Android AICore storage spikes, this explanation provides much-needed clarity. Instead of a mysterious bug or runaway process, you’re looking at a deliberate backup strategy. The storage space is temporarily doubled — typically by a few gigabytes — during the transition period. After 72 hours, the old model is automatically deleted, and your storage returns to normal.

This means that if you see a sudden jump in AICore’s storage usage, don’t panic. It’s likely just a model update in progress. You can check your storage settings to confirm, or simply wait a few days. Google recommends letting the process complete naturally rather than trying to clear cache or force-stop the service, which could interrupt the update.

On-Device AI is worth the storage cost — but Google needs to be upfront

The broader case for on-device AI is genuinely compelling. Sensitive data never leaving your device is a meaningful privacy win in an era when everything seems to be vacuumed into the cloud somewhere. Features that work in airplane mode are more useful than they sound when you’re somewhere with patchy connectivity. And local processing simply feels snappier than waiting on a server response.

But the goodwill only stretches so far when users are left staring at an unexplained storage spike with no context. Documenting it now is the right call — it just shouldn’t have taken this long to get there. For more on managing device storage, check out our guide on freeing up space on Android.

What Gemini Nano brings to your phone

Gemini Nano is Google’s lightweight AI model designed specifically for mobile devices. It powers features like smart reply suggestions in messaging apps, real-time call screening, and on-device translation. Because it runs locally, it can process data without sending it to Google’s servers, which is a major privacy advantage. However, this local processing comes with a storage cost — the model files can be several gigabytes, depending on the device and version.

Google has been expanding support for Gemini Nano across more Android devices, including the Google Pixel 8 Pro and newer models. As more apps integrate these AI features, the storage footprint of AICore will likely grow. But with this new explanation, users can at least understand what’s happening behind the scenes.

How to check and manage AICore storage on your device

If you’re curious about how much space AICore is using on your phone, here’s a quick way to check:

  • Open Settings on your Android device.
  • Go to Storage or Device Care (depending on your manufacturer).
  • Look for AICore or AI Services in the app list.
  • You’ll see the current storage usage, which may be elevated during a model update.

In most cases, you don’t need to take any action. The storage will normalize after the update completes. However, if you’re running low on space and need to free up gigabytes quickly, you can temporarily disable some AI features in Settings > AI Services. Just be aware that this will turn off features like smart replies and scam detection until storage is available again.

The bottom line: AICore storage is a feature, not a bug

Ultimately, Google’s explanation turns a frustrating mystery into a sensible engineering practice. The temporary storage spike is a safety net — ensuring that if a new AI model update goes wrong, your phone doesn’t become a brick waiting for a multi-gigabyte re-download. It’s a trade-off that makes sense, especially for users who rely on on-device AI for privacy and offline functionality.

Still, Google could have handled the communication better. A simple notification or a note in the storage settings would have saved countless users from confusion and frustration. As AI features become more central to the Android experience, transparency around storage usage will only become more important. For now, at least, the mystery is solved.

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.
