It should be possible to reverse engineer this, if it works on windows?

> The laptops also support unified memory configurations up to 128GB, shared between CPU and GPU, which is unusual for a laptop and central to why they’re being marketed at AI developers in the first place.

This isn't rare on laptops, pretty default on AMD with iGPU

I though the same, reverse engineer with AI. Even run the AI on the laptop and have it reverse-engineer itself.

I remain puzzled why anyone would want to do inference on a laptop if they have a home internet connection and a phone.

If you really want to do DIY inference, plug it in at home and set up tailscale so you can access it on the go.

No huge battery drain or toasty hot laptop required. Lower cost laptop. Lighter laptop. Longer battery life laptop. Win win win win.

Not everyone grew up in a situation where home was a stable dependable place. Not everyone has a home to go to. If you have it with you, they can't mess with it or take it away from you when you're not there. If you grew up in a broken home, you would understand.

And those people are buying $10k laptops to run local AI?

Those people won't be buying the Spark laptop, but asking "why anyone would want to do inference on a laptop" is broader than what the article covers.

Local AI is an expensive hobby. You're paying big money for small performance (so mainly for the feeling of "owning it", which is a great motivator). It can't match cloud services, not absolutely nor bang-for-buck, especially if you look a bit for cheaper and freebie options. As someone who loves and promotes local AI, in the situation you described my plea would be to use that money to improve your situation more directly (move out, get support,...). The cost of a laptop that can run somewhat decent models should buy you at least several months of therapy (@1 session/week).

You can't put a price of sending all your IP to a dubious third-party. Sorry. You argument apples vs oranges.

If you want local AI, which I absolutely encourage you to, I agree with the OP. Get a (mini)-PC and set up a VPN. It's going to save you money compared to a laptop, short- (usually cheaper) and long-term (usually better upgradeability). You'll have more money for therapy, which I would also encourage you to consider if you come from a broken home, as the GP mentioned.

The spark laptop in its present form is not very good, in fact, it’s disappointing.

If the security of your home possessions is an issue, it should be addressed first before you spend thousands on a very stealable laptop that you need to carry everywhere.

Because maybe you don't want to send your private data to a company that could use it for whatever it wants?

GP isn't proposing using closed proprietary models over an API, they're proposing having local hardware serving open weight models at your house/apartment being remotely accessible through an overlay network like Tailscale. The idea being that local inference is very hungry for power and thermal budget, so you run the inference somewhere that power and thermal headroom is abundant (your house/apartment, on a tower, or dedicated unified memory boxes like DGX Spark, Strix Halo, Mac Studio, etc) and then remotely utilize that inference from a regular laptop. You still get all of the benefits of local, private AI inference, without having to expend a laptop's limited power and thermal budget on doing the inference on the laptop itself.

Can you explain what data is going where?
entrope 12 minutes ago||
Your prompts and whatever data they collect from your dev environment go to the inference provider, and typically the customer has neither control nor assurance over what the inference provider (re-)uses that data for.

The RTX Spark is also sold in a mac mini form factor. That's pretty well suited for home inference.
barrkel 33 minutes ago||
Exactly. Get yourself a DGX spark and plug it in at home.

I meanwhile, run my ridiculously OP workstation class hardware as a server - 9995wx, 768GiB, rtx pro 6000 w/ 96GiB vram - at home, and my Asus ZenBook is light, cool, and long-lived.

Runs GLM 5.3 flash at 35 tok/sec while consuming only 15 GiB VRAM, and I can run a lot more stuff on there alongside.

private memory.

unique local data and know how not shared with cloud.

What part of what I said implied data was going to the cloud?

I have been saying this for years, and the answer hits a nerve that gets you downvoted into oblivion: people prefer the aesthetics of laptops, simple as that. They will absolutely go to the grave arguing that they need the mobility etc, then just leave it plugged in. They simply prefer how laptops look, and they absolutely hate it when someone dares say it.

I have a laptop for work. 95% of the time i'd prefer a tower or at least a mini PC with proper cooling, but that remaining 5% i have to be around with the laptop is enough. I don't like the idea of having to remember to sync the projects every time (especially while i'm in the middle of testing something new so it's not like i can just pull the latest commit or sync the latest good version of something)

To be absolutely crystal clear:

I am not saying don't use a laptop.

I am not saying you have to use cloud inference.

I am saying using a laptop for inference is dumb. If you want private inference:

- use a dgx spark or similar plugged in at home

- set up tailscale so you can connect from anywhere

- use your phone as a hotspot on the go

- work on your laptop, using tailscale to connect to your home inference server if you're on the go

This gets you everything except for the few hours you might be on an airplane.

If you do any travel whatsoever a laptop is usually not optional.

So weird that everyone gives Microsoft a complete pass. They probably paid Nvidia to give them a head start so people would be forced into Windows and WSL for awhile.

I am starting to wonder whether CEOs everywhere ( but especially in US ) are simply unable to read the room. I shrugged off nvidia when they did it to gaming and mining ( it annoyed me, but ultimately there were options to deal with it ), but here it is touching a much wider populace with repercussion well beyond crypto and gaming.

Nvidia being the shittiest hardware vendor for GNU/Linux, as always.
petercooper 2 hours ago||
Assume I'm naive on this matter, but why wouldn't Nvidia allow its own DGX OS to be a first party OS on these devices? Some sort of MS subsidy? Ecosystem-wise, wouldn't it make sense for Nvidia to keep pushing its own OS on all the devices containing its hardware?

Unrelated to this slowdown, I could imagine this sort of thing being the right application for things like Taalas, although I'm not quite sure whether it can actually offer what I imagine that it can (i.e. ability to make a cheap, physically small card that can run a large model).

A laptop can't run the latest big models, because memory is too expensive. This thing probably can't run models larger than Mistral Small 4. But it'd be a completely different thing to have a hardcoded Mistral Large 4, than a choice of tiny models.

You probably won't be able to run a sota model on a single Talaas card. You probably need a set. It should theoretically be cheaper, faster, more power efficient than Nvidia at running that model. But then you are stuck with a chip that can run only that model. And I understand that context size will also be a problem.
impossiblefork 2 hours ago||
Yeah, that was why I felt that, while Taalas might not be the right thing in general, it could be really appealing in a laptop, that would otherwise not be able to run any big model at all.

I think I misunderstood what the technology could do a little bit, because I imagined these fixed matrix multiplies encoded into hardware as small-ish, as using routing space etc., not just fast.

I think what I really imagined was useful would be more easily achieved by having a big ROM with model weights connected to an ordinary GPU.

2 months old laptop has power management issues on Linux. What a suprise!

Still miles ahead compared to Apple, where linux does not even boot on newer macs!

I do wonder how much it would cost to "clean room" engineer the firmware using AI.

Remember when Apple was slowing down iPhones, the outrage!

But with Nvidia people just expect they nerf all the features.
