Nvidia’s largest customers have been notified that servers containing its AI chips will rise in price by more than 15% in many cases from early next year, driven by memory costs. The company reports quarterly earnings next week.

Nvidia’s biggest customers have been told what the memory shortage is going to cost them. Servers containing its AI chips will rise in price by more than 15% in many cases, on systems shipping from early next year.

The increases reach the newest hardware. Systems built around the Vera Rubin and Grace Blackwell chips are affected, with the size of the rise depending on the chip generation and the memory configuration.

The warnings came through the middlemen. Companies that assemble servers under contract for operators including Microsoft, Google and Oracle have notified their customers, and Nvidia did not respond to requests for comment.

What makes this notable is who is passing on the cost. Nvidia holds a gross margin of about 75% and is the most valuable listed company in the world, and it is still not absorbing this.

The leverage sits with three companies. Samsung, SK hynix and Micron produce most of the world’s DRAM, and while output is rising it has not caught up with demand from AI infrastructure.

Consumers met this first. Apple and Qualcomm have both said component costs are pushing prices up, Nvidia raised its gaming card prices this month and AMD followed within days, while Amazon Web Services has already put GPU prices up 20%.

Europe’s exposure runs through public money as much as private. The EU has committed around €20bn to a set of AI gigafactories, and a French consortium has bid $10bn for one site.

Those bids and budgets were built on last year’s hardware prices. A 15% increase on the servers such a facility exists to buy is a material change to a plan drawn up before the memory market tightened.

Commercial European operators are buying into the same market. Nebius is tripling Nvidia capacity at its Finnish data centre, on economics that have just moved.

The build-out was already getting harder. Project delays, labour shortages, tighter capital markets and local opposition have complicated data centre plans, and this adds cost to all of it.

Nvidia reports quarterly earnings next week, which is when the useful question gets asked. Not whether demand is holding, but who ends up paying for memory, because at the moment the answer appears to be everyone downstream.

People who used Grok Lite this week were no doubt surprised when the bot started sending long, large paragraphs of total gibberish. This is only slightly worse than its usual output, but it still had people in a tizzy, and understandably so.

The trouble started earlier in the week, with multiple people posting on Reddit that Grok had “lost its mind,” meaning the chatbot was acting strangely. Though the bot would respond normally at first, it would devolve into buggy, nonsensical rants. The problem appeared to only impact Grok’s website interface, not mobile apps.

In response to a perfectly reasonable question, Grok responded: “Some is local but is add, and safety font but proper if research use glue for already.” Even the basic autocorrect in my web browser gets angry at that sentence.

Users reached out to Grok directly to ask what the problem was. The chatbot responded on X that the “pure word salad is a rare temporary generation glitch” and that users could fix the problem by refreshing their browser tab or starting a fresh chat. That solution appears to have worked for most people.

Instances of the glitched responses seem to have subsided as of Friday, and we were unable to replicate the problem.

LLMs are machines, and they break as machines do

The cause of the glitch remains a mystery, as xAI hasn’t released any technical details. While it’s amusing to make fun of Grok for its mediocre performance, dwindling user base and rock-bottom satisfaction ratings, the fact is that it’s little more than computer components and code, and sometimes those things just break. 

ChatGPT had a similar issue in 2024 as did Gemini, where users were getting incomprehensible feedback to mundane questions and tasks. Claude had its own bout of silliness in 2025, though it seemed to be limited to people who used it for coding purposes.

Ultimately, all large language models, or LLMs, are word-guessing games that work similarly. Chatbots use complex mathematical formulas to predict the most likely next words in their responses. When this process breaks down, gobbledygook happens. Such a breakdown can occur at any point, whether due to a broken code or a math glitch. 

AI companies tend to keep these issues close to the vest, and it appears xAI is doing the same with Grok. So, it’s not you. It’s it.

The Pixel Watch 5 is here, but it probably shouldn’t be – just yet, anyway.

Google’s latest smartwatch has finally launched in the UK, US and beyond, bringing with it a familiar design, familiar hardware and the promise of several genuinely useful new features. 

The problem? Most of those features aren’t actually available yet, making the Pixel Watch 5 feel like a placeholder for the smartwatch Google actually wants to – and will – sell in a few months’ time. 

The Pixel Watch 5 is here, but most new features aren’t

The Google Pixel Watch 5 is finally available to buy in the UK, US and most other regions around the world – but it’s not really ready yet.

At the Made By Google event earlier this month, the company outlined key new features coming to the wearable. These include sleep breathing quality monitoring, which helps track your breathing quality while you sleep, improved exercise tracking with support for weight workout plans and HIIT, blood pressure and insulin trends, and even the ability for the watch to detect whether you’ve stopped breathing and call emergency services on your behalf.

These are all more important than usual because, in terms of hardware, the Pixel Watch 5 is almost identical to the Pixel Watch 4. It has the same design, the same weight and thickness, the same screen with the same peak brightness and even the same battery. 

The only tangible difference in hardware comes from the processor itself – but even the jump from the Watch 4’s Snapdragon W5 Gen 2 to the Watch 5’s Snapdragon W5 Gen 2 Accelerated isn’t that dramatic. 

Google itself only claims around 20% improved performance year-over-year, and even with the accelerated version under the hood, it’s still not quite as powerful as the Snapdragon Wear Elite found in the similarly priced Samsung Galaxy Watch 9.

What I’m trying to say is that Google is relying entirely on software smarts to entice fans to the Pixel Watch 5 instead of the near-identical, and much cheaper, year-old Pixel Watch 4 – which makes the fact that most of the features are MIA at launch all the harder to accept.

A staggered, rather confusing rollout

Rather than booting up your new Pixel Watch 5 and having all features available to you, it depends on whether it’s available – and even if it is, it might not be available in your territory.

Take one of the headline features of the Watch 5 as an example. The breathing emergency detection feature is available at launch in select countries in the EU, including France, Spain, Germany and others, along with the UK – but not in the US, as it didn’t get regulatory approval in time for the wearable’s launch. As such, there’s no hard timeline for when the feature will become available to those in the States.

Then there are features like the improved weight workout plan support and sleep breathing quality monitoring that are on the way to all users, but not until sometime in September. It’s a similar story with blood pressure and insulin trends; the feature will roll out in September, but as it needs a full month of data, the first reports won’t arrive until the end of October. 

And without most of those key features on the watch from day one, it feels almost identical to the Pixel Watch 4 experience – except it now costs more money, because, of course it does.

A hard pill for Google’s biggest fans to swallow

It makes my job as a tech reviewer all the more difficult, as I can only evaluate what’s here today, not what might appear a little further down the road. 

It’s not like we can take companies’ promises at face value either; Apple promised AI smarts with the iPhone 16, including a redesigned Siri experience, but the latter is only launching in the next few weeks, likely alongside the iPhone 18 Pro, two years later. And we wouldn’t be doing our jobs properly if we recommended products based on features we’ve not seen or tested, which in part contributed to me giving the Pixel Watch 5 four stars instead of something closer to five. 

But really, it’s the die-hard Google fans who rush out to pre-order Google’s latest tech that really get the worst deal. These people could wait a few months for the prices to start dropping, but no, they want the best Pixel Watch experience possible, as soon as possible, and they’re willing to drop money before even reviews are available to guarantee that. 

And after all that, they’ll boot up the Watch and struggle to spot anything that’s actually new – and it’s because right now, there just isn’t. For all intents and purposes, it’s the same Pixel Watch experience we’ve seen for a year, just with a few minor UI changes and promises that things will get better in the coming months.

Well, if that really is the case, why not just delay the Pixel Watch by a month or two until it’s actually ready?

Just wait until it’s actually ready to go

I can’t help but feel that Google would’ve had a much warmer reception to its Pixel Watch 5 if it had simply delayed it by a month or two until all the new features were ready, present and accounted for. 

It’s not like Google hasn’t had long gaps between announcement and release before; the Pixel Watch 4 was announced in August 2025, but didn’t materialise on shelves until two months later, in October 2025. 

Of course, we all know the real reason why. It’s the same reason why it shifted from its original October release schedule to August: to get ahead of Apple’s yearly iPhone launch, which takes place in early September. 

If Google delayed the Pixel Watch 5 until October, it’d risk it essentially getting forgotten about in the noise of whatever Apple is set to launch in September, not only in terms of wearables like the Apple Watch Series 12, but also in general excitement around the next-gen iPhones – especially if the long-rumoured foldable materialises, as expected.

So, instead, Google has stuck to its guns to cash in on early interest, even though that has seemingly come at the expense of early adopters who now have to wait a few months before really getting the Pixel Watch 5 experience promised at launch. Bad move there, guys.

Quarantining leaked credentials is not good enough

One of the best ways to lower your AWS bill by 99 percent or more is by not checking your keys into public GitHub repositories. Many of us have done this inadvertently over the years, and the defenses against it have improved dramatically (my personal favorite being “using non-ephemeral credentials derived from OIDC or SSO is an anti-pattern”), but it still happens.

On Friday, BleepingComputer reported on a Truffle Security finding that hundreds of leaked AWS keys are root keys and are somehow still active and valid.

AWS Security is full of very smart people who care deeply about a number of things, including “not abetting crime.” If they detect (usually via automated means) that a credential has been leaked, they’re quick to apply a Quarantine Policy to it. Trouble is, that policy enumerates a bunch of bad behaviors in an ever-expanding graph of principals and associated behaviors.

AWS’ considered position on this is that they don’t want to break customer environments: “The policy aims to limit the potential damage that may be caused by fraud-related activity leading to unauthorized charges, while not impacting the existing resources.”

AWS’ considered position on this is wrong.

If I get access to your credentials (much less a root credential, good god), deactivating them may very well break your workload because anything that relies on those credentials will start failing. Until you rotate them, those workloads will continue to fail. That’s not good!

But I promise you, as a bad actor, I can do far worse to you.

Hold my tea

Go ahead and apply a quarantine policy to a credential set and toss it my way. I won’t be able to buy savings plans, read your S3 data, modify Lambda functions, and do a host of other things.

But here’s what I can do.

• Anything I damn well feel like on RDS. You don’t have anything important in databases, right?

• ssm:SendCommand / ssm:StartSession are permitted, which means I can run commands as root on EC2 instances, which will in turn invoke with that instance role’s permissions.

• sts:AssumeRole means that I can assume any other role in the account and get its permissions, rendering the entire restriction list potentially moot.

• I can use autoscaling:CreateAutoScalingGroup / UpdateAutoScalingGroup to launch instances via the Auto Scaling service-linked role, so the ec2:RunInstances deny never applies.

• cloudtrail:LookupEvents gets denied (that’ll stop you from… reading the audit log), but I can call both cloudtrail:StopLogging and DeleteTrail which do exactly what you expect; you don’t have an audit log anymore.

• SES denies ses:GetSendQuota / ListIdentities actions, but y’know what’s missing? SendEmail, so I can blast my spam out to your entire list.

• sns:GetSMSAttributes means I can’t get your SMS configuration, but I can absolutely sns:Publish to send fraudulent text messages wherever I’d like.

• s3:DeleteObject gets denied, but s3:PutObject is allowed. I can’t delete your data, but I can fill a bucket to petabytes.

• Next, they fail to block s3:PutBucketVersioning, s3:PutObjectLockConfiguration, s3:PutObjectRetention, and s3:PutObjectLegalHold. So on any existing bucket, like that one I just stuffed petabytes into, I can enable versioning, turn on Object Lock, and set a bucket-default COMPLIANCE-mode retention out to 2126, or alternatively slap it on per object. COMPLIANCE retention can’t be shortened or removed by anyone, including the account root and AWS Support. The only way to remove it is to delete the entire AWS account.

• secretsmanager:GetSecretValue, ssm:GetParameter* (WithDecryption), and kms:Decrypt are all unencumbered, so your secrets are now my secrets. Sharing is good! 

• Backups are important, so it’s a shame you don’t have any. Well, not after I kick off backup:DeleteRecoveryPoint / DeleteBackupVault, and rds:DeleteDBSnapshot. 

• If you’re using CloudFormation, and for some things you almost certainly are, cloudformation:DeleteStack going unmentioned means you’re not using it anymore and all of your stacks are gone.

I would make different choices

This isn’t a comprehensive list – just a few things that occurred to me over the course of about an hour. I’m not a bad actor; I’m almost positive that I’m missing a whole bunch.

AWS is almost certainly going to change this. My question for them is simply, “how big of a customer incident needs to happen before you do?” ®

F-B100W adds Bluetooth and step tracking while keeping a two-year battery

Casio has added Bluetooth and step tracking to a £55 digital watch without turning it into a smartwatch or sacrificing replaceable-battery convenience.

The snappily named F-B100W pairs with Casio’s smartphone app to record activity, adjust settings, and keep its clock accurate. Despite the additional electronics, Casio claims approximately two years of operation from a replaceable CR2016 battery.

It is very much not a smartwatch. There is no touchscreen, app store, or stream of notifications – just a conventional digital watch with a step counter and a little Bluetooth connectivity. That combination has nevertheless attracted attention on Hacker News and Reddit.

We admit it: this ape-descended life form is so astoundingly primitive that he still thinks digital watches are a pretty neat idea.

Douglas Adams first mocked humans’ fondness for digital watches when the original Hitchhiker’s Guide to the Galaxy was broadcast in 1978 – nearly half a century ago. The Casio F-91W is only a decade younger. This strangely ubiquitous watch, once labeled a supposed “sign of al-Qaida,” is widely regarded as the classic quartz digital watch and has been described as the bestselling watch of all time. One reason is that it’s only £20 ($30) new. Another is that if you bought one of the first batch, it’s probably only on its third or fourth battery by now: they are rated for seven years, but often last longer.

The F-91W is very simple and very cheap. Its main rival for all-time bestselling watch is the reverse: the Apple Watch has also shifted about 300 million units.

This is not a radical innovation for Casio. The existing ABL-100 does much the same, but costs over 25 percent more and weighs more than twice as much. What is interesting is that Casio has brought the functionality to a smaller, cheaper, and lighter watch – and possibly a more robust one. It’s also retained an impressive battery life. These Bluetooth-enabled models should still run for two years or more on a single, replaceable, CR2016 lithium button cell. Since those only cost a buck or so, that sounds good to us.

The Reg FOSS desk has a fondness for inexpensive technology that performs a modest set of tasks well. Our first budget smartwatch was an Amazfit Bip, bought new for about £60 ($80). It had an always-on, daylight-readable color display, lasted a month and a half on a charge, and did everything we asked of it.

After five years of daily use, its battery stopped holding a charge. We replaced it with the then-latest Bip 5, only to find that the newer model lacked its ancestor’s always-on display and offered less than a quarter of its battery life.

Our next move was therefore backward to a secondhand Amazfit Neo. It is the most basic smartwatch we have encountered. A conventional segmented LCD displays the time, while a smaller strip cycles through the world clock, step count, pulse, estimated calories burned, battery level, and waiting notifications. It cost £15 ($20) and still lasts a week and a half on a charge.

This “beyond retro” design is, we need hardly say, no longer made. That is why Casio’s move in the opposite direction – adding a few connected features to a basic digital watch – interests us.

We found the existing threads about these devices highly educational. There’s a whole world of digital watch geekery that we barely even knew existed.

Some posters raised concerns we found very relevant. For instance, the vexed issue of date formats: it seems many low-end Casios can only display dates in US MM/DD format. Apparently, to get European-format dates, you need to go to more high-end models such as the GW-M5610U-1ER at a princely £135 ($185).

These lower-end Bluetooth-equipped Casio devices send only one Bluetooth Low Energy update to the phone at the end of each day, which is why they can boast such impressive battery life. In its pricier G-Shock range, the company does offer devices with bidirectional Bluetooth support, so that the watch can display on-screen notifications, such as the £129 ($165) G-Squad GBD-200 and GBD-300. Better still, it seems these can deliver silent vibrating alerts.

Another concern is that officially syncing these watches requires Casio’s proprietary smartphone app, but there are FOSS alternatives such as Casio G-Shock Smart Sync.

The Register asked Casio for more information and a review unit but had not received a response at the time of publication. ®

As Harvard Business School seeks to expand its reach, it’s leaning on AI avatars to provide individual feedback.

These avatars were created by a startup called HeyGen and are included in the eight-week, $699 HBS Foundry bootcamp for entrepreneurs. The program offers live sessions with instructors every week, but the AI avatars are the ones providing feedback during practice pitches and board meetings.

New York Times reporter Sarah Kessler actually tried this out herself by pitching an AI-generated copy of Flybridge Capital co-founder Jeff Bussgang. Apparently, both the real Bussgang and his simulacra were unimpressed by her plan to build “Uber for bananas,” but Kessler said the virtual version offered a noticeably frozen smile during her pitch.

Project director Katharina Rings said she initially envisioned the AI component as something closer to a chatbot. However, after HBS released a trial version, students said they wanted a more guided experience.

And while some college students haven’t been shy about expressing their negative feelings towards AI, Foundry participants told Kessler they like the avatars. As for Bussgang, he acknowledged his digital copy is a little “creepy,” but he said, “My students love it.”

An anonymous model called Ox Alpha appeared on OpenRouter last week, free to use with a million-token context window, and developers have been impressed. OpenRouter’s own listing says prompts and completions are retained by the unidentified provider.

A model that nobody will take credit for is being tested across the industry. Ox Alpha appeared on OpenRouter last Thursday as a stealth release from an anonymous third-party provider, free to use, with a context window of just over a million tokens.

The scale on offer is not modest. The open-source agent OpenCode said the model would be free for a week with near unlimited usage, and that its provider had capacity for 100 trillion tokens a day.

Developers rate it. Stripe’s chief executive Patrick Collison tried it and called it “very impressive,” and it is positioned for coding, long-horizon agent work and production use.

The guessing game has been inconclusive. The leading theory points to Z.ai, which previously tested GLM-5 anonymously under another name, while a competing analysis of its tokenizer suggests Microsoft’s MAI family instead, in a market already reshaped by free Chinese models.

By the weekend the confidence had drained out of every theory. The AI analyst Andrew Curran wrote that people seemed “less sure of anything” than they had been the night before.

The more useful detail is not the identity but the terms. OpenRouter’s own listing states that prompts and completions “are retained by the provider and are not used for training.”

Read that again with a work project in mind. Whatever you send goes to a company that has not said who it is, and it keeps it.

For European businesses that is not an intrigue, it is a blocker. Data protection law requires a contract with a named processor and an assessment of where data goes, neither of which is possible when the counterparty is anonymous.

The timing sharpens it. The AI Act’s transparency obligations took effect on 2 August, with penalties reaching €15mn or 3% of global turnover, in a regime built on knowing which provider is responsible for what.

None of this makes the model bad. Open-weight releases have closed the capability gap faster than the safety one, and a stealth launch is a legitimate way to benchmark a model before announcing it.

But free has a price here, and it is information. Somebody is paying for 100 trillion tokens a day of inference, and until they say who they are, the sensible European position is to test Ox Alpha with nothing that matters.

Most people who want the newest phone look at the Ultra or the latest foldable. Meanwhile, Samsung’s Galaxy S25+, priced at $679.99 (was $1,000), delivers the same daily performance without the increased weight or cost. A year and a half after its release, it is still in that unusual position where the hardware feels modern while the software continues to improve.

The phone’s round aluminum edges and glass sandwich provide a really substantial feel in the hand, which you’ll quickly get used to. At 190 grams and just more than 7mm thick, it’s pleasant to hold for as long as you need. The camera is placed low enough so that when you set the phone on a table, it does not rock or tilt to one side. The IP68 rating means you won’t have to worry about rain or the rare accidental splash of water spoiling anything.
