Wtf. Are we actually seeing a push towards being 100percent dependent on the cloud?

Sovereign AI has never been more important.

Controlling AI is so much more powerful and impactful than controlling search or social algorithms.

Centralized AI a 10x on social control over everything we have seen before, and there is no way that a free and open society survives contact with centralised, high capability AI if the system is manipulated towards guiding outcomes. It’s essentially mind control, as people will offload an even greater share of their cognition to AI than they do with search and social.

Build and maintain sovereign AI while you still can.

No, we are just seeing a push towards Nvidia wanting to make money.

Nothing stops you from giving Nvidia half a million for their latest and greatest AI GPUs, unless you are in China I guess, but China does very well despite the export control.

It is just classic market segmentation, the thing Nvidia and just about every company that can benefit from it has done for decades. Cloud providers are ready to pay a lot of money, consumers wanting local AI have a lower budget, and gamers even lower. But a low budget is greater than zero, and there is still money to be made on these markets. But they also don't want to compete against themselves, so they are going to find ways of crippling enterprise-class workloads on consumer hardware.

It used to be that they crippled high precision arithmetic on consumer hardware, because it was a differentiating factor, but AI doesn't care about high precision, so now, it is something else.

Given the history of prohibition in the past few centuries, it wouldn't surprise me if it is much easier to buy Nvidia products in China than in the US. The price is much higher most likely, but the actual transaction is likely easier.

Unless the US somehow differs from the EU in some major ways, can't you just walk into a store and buy a NVIDIA GPU? Not sure how much easier it can get. And yes, it's as easy in China to, walk into store, point at GPU, fork over the money, you get your GPU. Like everywhere else, except the US I suppose?

NVIDIA probably already figured out that local will be massive part and are preparing to do DRM for AI.

Pay up for license to unlock full capacity, pay up for license to use encrypted models from AI moguls, paid per billion tokens processed or just operations in GPU

Is DRM going to work considering how good LLMs are in reverse engineering? I would say it is a fools errand at this point.

AI is actually the perfect use case for homomorphic encryption.

I wonder if this space is explored fully enough at the moment.

Aside from some implementation details, it's conceptually much easier than doing it for a SQL database.

AlAjem 2 hours ago||||
I don't see the case for DRM protected local models on either side.

The consumer has access to free and open models for local use.

The supplier has better control and wider market to serve running the models in data centers.

Only way I can see encrypted models being widespread is if they are bundled as part of a software package (OS/Browser/etc) and not sold as the product.

There's good open weight models for now, labs could stop releasing them for whatever reason (assuming "good model" is a moving target).

The reason why open source couldn't win search and social was because they need network effects which is not possible for open source maintainers.

AI is a software just like operating systems and executables where open source absolutely dominates the industry. Remember when the compiler engineers optimized the shit out of llama.cpp.

Right now the bottleneck for AI software is compute and data. Moore's law is give us compute, StackOverflow, arXiv (and it's children like bioRxiv), gutenberg and others (3lib, anna, internet.org) will give us data.

It's a waiting game. Open source always wins.

Tons of stuff happenning behind closed doors today though. No more stackoverflow for the next decade, that could create a problem if all new context only exists in chatgpt conversations only openAI has access to (or whoever).

Years ago I would think I was being paranoid to think they would patch hardware retroactively to make it slower so you need to pay more to use your own hardware. In 2026, I think this is what all car companies are doing after you pay the full car price. I don't see a reason why they wouldn't do it with so little competition

It smells like something IBM would do. Coming from small computers where you own it, I was flabbergasted to learn that IBM would ship additional processors and ram with their mainframes but you were not allowed to use them until you paid the additional license fee.

So it is something that has been done for a long time now. Still feels like unethical rent-seeking that should not be tolerated by the customer.

See Also: car companies that charge additional fees for hardware already on the car. Additional services, I sort of understand(remote start via cell network), but stuff like heated seats, that is just wrong.

It saves the car manufacturer on logistics cost. The per-unit cost of a seat heater is (much) smaller than the cost related to keeping two variants of seat in stock and to provide spare parts. Say the heating mat costs 100€ per seat including materials and installation, and can be sold to the customer for 400€ permanent, that means as long as 1 in 4 customers buys the seat heating option, the books are balanced, and all money you save on logistics is pure profit.

Adding subscription on top of that is financially even better, if there is one thing companies LOVE thanks to stonk market incentives it is monthly recurring revenue.

You are absolutely right! (Couldn't resist the ai pun)

I think more than that, it is probably a lie they tell us that you are not paying for the hardware/equipment.

[Hanlon's Razor] This is such a contrived performance drop scenario that I find it hard to believe it was done with the purpose you're inferring.

I'd interpret this as Nvidia not caring that much about Linux desktops/laptops once again (as opposed to Windows desktops/laptops), rather than anything to do with local vs cloud.

Yes? How is this at all surprising given....everything we've seen tech companies push for for years and years? People are fully embedding themselves and their workflows in the services of big, closed companies, and are going to be surprised when they finally feel able to clamp down? There has been warning sign after warning sign, but people are only increasing their dependence.

Nvidia doing what Nvidia has always done; proprietary closed drivers. Weird choice to cryptographically protect the power settings. Key problem is that we've allowed a company that's always been this way to form a monopoly. Other brands exist, perhaps it is now worth the effort to migrate and rebuild elsewhere.

> we've allowed a company

When did "we" have a say in this? I don't get these types of comments from the "open-source as a community."

Nvidia has been doing this for decades, and there are two possible arguments:

1. They are successful despite it.

2. They are successful because of it.

There is no mythical collective "we" representing the open-source community in Nvidia's supply chain of success. It's Nvidia and its consumers.

You will never stop me. As I and everyone like me, before and after me, have shown, time and time again. And by me, I mean nature. And by nature I mean math and logic unchangeable in any possible universe. You cannot give me a thing without me having it. If a thing exists, I can copy it, know it, and bring it's equivalent into existence. Nothing can be created that is not indelibly written into the the intricate cause and effect chain of history. A perfectly encrypted thing is indistinguishable from the noise of the cosmos, but if I want I thing, it shall soon emerge, free from any control from that noise, which is the weight of all that has happened, just as surely as I can count to a number.

If you want to prosper with the current of nature, provide a thing easily for mutual benefit. The more you try to block a thing, the sooner your demise into uselessness.

Enumerating 3 things really ..sparks a comment nowadays? Doing that as a rhetorical device has been a thing for generations and of course LLMs mimic it because it is everywhere in their training data.

I just heard a quick J. Talarico speech at some country concert. In the 10 or so sentences he spoke, he had 3 or 4 instances of doing this "Claudism" enumeration. Are you saying Texas just elected Claude for Senate?

Maybe we should stop with such superficial judgements. It's the modern equivalent of not liking the speaker's tie. (Doesn't mean the speaker's speech is good, but it doesn't mean it's bad either.)

fxwin 1 hour ago|||
There are more Claude-isms in there than just rule of three (Hence -isms and not -ism), and while I'd generally agree that we generally shouldn't be superficial with our judgements, this particular heuristic has served me pretty well so far. I don't know what Talarico speech you are talking about, so i won't comment on that (But I'm not sure if political speeches are the best rebuttal to "I think obviously AI generated text is an indicator of low signal-to-noise ratio").

Edit re "equivalent to not liking the speaker's tie": This is not equivalent at all, this is a written blog post and I'm put off by the way it is written, not by say the URL or their chosen font. It's more akin to a speaker dropping an inappropriate joke at the start of their talk and leaving because of that

Nvidia was already a bad choice for Linux because of closed drivers.
adrian_b 38 minutes ago|
Not really, because for more than 2 decades the closed-source NVIDIA Linux drivers were at parity of features and performance with the Windows drivers, unlike the AMD drivers before they were open-sourced, which was much more recently.

This is a new thing with the firmware that can be used only by Windows. If this NVIDIA policy continues, then NVIDIA will indeed become a bad choice for Linux, but until now, for graphics and AI applications NVIDIA has been the best choice for Linux, by providing the best performance and reliability.

For pure computational applications, especially for those requiring good FP64 throughput, there are many years since NVIDIA has become a worse choice than AMD and more recently also than Intel, but that is due to poor hardware support, not to bad software support.
