Raspberry Pi's New AI Hat Adds 8GB of RAM for Local LLMs(www.jeffgeerling.com)

I think Raspberry lost the magic of the older Pis, they lost that sense of purpose. They basically created a niche with the first Pis, now they're just jumping into segments that others created and are already filled to the brim with perhaps even more qualified competition.

Are they seeing a worthwhile niche for the tinkerers (or businesses?) who want to run local LLMs with middling performance but still need full set of GPIOs in a small package? Maybe. But maybe this is just Raspberry jumping on the bandwagon.

I don't blame them for looking to expand into new segments, the business needs to survive. But these efforts just look a bit aimless to me. I "blame" them for not having another "Raspberry Pi moment".

P.S. I can maybe see Frigate and similar solutions driving the adoption for these, like they boosted Coral TPU sales. Not sure if that's enough of a push to make it successful. The hat just doesn't have any of the unique value proposition that kickstarted the Raspberry wave.

Yep. RPi foundation lost the plot a long time ago. The original RPi was in a league of its own when it launched since nothing like it existed and it was cheap.

But now if I want some low power linux PC replacement with display output, for the price of the latest RPi 5, I can buy on the used market a ~2018 laptop with a 15W quad core CPU, 8GB RAM, 256 NVME and 1080p IPS display, that's orders of magnitude more capable. And if I want a battery powered embedded ARM device for GPIO over WIFI, I can get an ESP32 clone, that's orders of magnitude cheaper.

Now RPi at sticker price is only good for commercial users since it's still cheaper than the dedicated industrial embedded boards, which I think is the new market the RPI company caters to. I haven't seen any embedded product company that hasn't incorporate RPis in its products they ship, or at least in their lab/dev/testing stage, so if you can sell your entire production stock to industrial users who will pay top dollar, why bother making less money selling to consumers, just thank them for all the fish. Jensen Huang would approve.

I still use Pis in my 3d printers. Laptop would be too big, and a ESP could not run the software. "China clone" might work, but the nice part of the pi is the images available. It just works™

I'm also currently building a small device with 5" touchscreen that can control a midi fx padle of mine. It's just so easy to find images, code and documentation on how to use the GPIO pins.

Might be niche, but that is just what the Pi excels at. It's a board for tinkers and it works.

You can run Klipper on any Linux SBC with a USB port, RPi works but so does an old router that supports OpenWRT, a cheap Android TV box that could be flashed to run Linux, or any of the OrangePi/Banana Pi/Alliwinner H3 boards. You don't really need hardware UART because most of the printer boards you'd be using have either native USB or USB to UART converters. For that pedal, would an old Android tablet that supports USB OTG work? Because that's got to be much cheaper, and with much better SDK.
Mashimo 1 hour ago||
Correct. But when I looked into it a few years back fir OrangePi it was not as easy as downloading raspbian. All the images made for the pi would not work, you had to download a kernel from another place or something like that? Sorry I don't remember the details, but it was not as easy as a pi.

How much cheaper then 50 bucks can a tablet get? With the pi I can quickly in a hacky way connect rotary encoders with female-female dupon cables, use a python GPIO library made for raspberry pi.

I can also use it for Zynthian. And if I'm done with it, I can build a new printer :P

Yeah, Pi 5 2gb is ~20% more expensive compared to pi3b on release, factoring in inflation (Both in including VAT and local prices)

It's 10 bucks more. ¯\_(ツ)_/¯ Still half the price that I see intel NUCs for sale. Which of course are way more capable. But still, I don't mind the price that much.

I could go with a cheaper alternative, but then AFAIK you might have to fiddle with images, kernel and documentation. For me that is worth 10 bucks.

>Yeah, Pi 5 2gb is ~20% more expensive compared to pi3b on release, factoring in inflation (Both in including VAT and local prices)

I don't really care how it compares to past models or inflation to justify its price tag. I was just comparing to to what you can buy on the used market today for the same price and it gets absolutely dunked on in the value proposition by notebooks since the modern full spec RPi is designed to more of a ARM PC than an cheap embedded board.

60 Euros for 2GB and 100 for 8GB models is kind of a ripoff if you don't really need it for a specific niche use case.

I think an updated Pi-zero with 2GB RAM and better CPU stripped of other bells and whistles for 30 Euros max, would be amazing value, and more back to the original roots of cheap and simple server/embedded board that made the first pi sell well.

Mashimo 3 hours ago||
A used notebook was also better in price to performance 10 years ago, no?
joe_mamba 2 hours ago||
Yeash, but not as good as an alternative to a PI back then, since 8 year old notebooks 10 years ago (so 18 year old notebooks today) were too bulky and power hungry to be a real alternative. Power bricks were all 90W and CPU TDW was 35-45W. But notebooks from the 2018 era (intel 8th gen) have quite low power chips that make a good PI alternatives nowadays.

The mobile and embedded X86 chips have closed the gap a lot in power consumption since the PI first launched.

Now you can even get laptops with broken screens for free, and just use their motherboard as a home server alternative to a PI. Power consumption will be a bit higher, but not enough to offset the money you just saved anytime soon.

What prices are you using for the 3b and 5 to get this percentage? The lowest percentage I got from available data is a 57% increase ($35 -> $55)

I had just gotten into Arduinos when the first Raspberry Pi came out.

I noticed I can do 90% of the stuff I'd use an Arduino for with a RPi, except I had the full power of an internet connected Linux machine available. The Arduinos are still collecting dust somewhere =)

But now we have the ESP32 filling the same niche along with the Pi Zero W, so I don't really understand the purpose of RPi 4 and 5. They're not cheap compared to the price nor very powerful in any measure.

You don't even need a full laptop, any Chinese miniPC will blow the RPi5 out of the water AND some of them have expandable storage+RAM, while also having 5-20x more CPU/GPU oomph. They do consume a few watts more power, so there _might_ be a niche for the Raspberry Pi, but it's not a big one.

yeah, depends on what the used market looks like where you live. Here I see way more laptops for sale for cheap than those enterprise thin clients.

And the thin clients when they are for sale tend to have their SSDs ripped out by IT for data security, so then it's a hassle to go out and buy and extra SSD, compared to just buying a used laptop that already comes with display , keyboard, etc.

RPi will still have lower power consumption and is far more compact. And mechanically reliable.

joe_mamba 2 hours ago|||
> And mechanically reliable.

What moving parts do competitors have to be less mechanically reliable?

In fact, a NUC or used laptop would be even more reliable since you can replace NVME storage and RAM sticks. If your RPI ram goes bad you're shit out of luck.

>RPi will still have lower power consumption and is far more compact.

Not that big of on an issue in most home user cases as a home server, emulator or PC replacement. For industrial users where space, power usage and heat is limited, definitely.

>I'm in the market to replace my aging Intel NUCs, but RPi is still cheaper.

Cheaper if you ignore much lower performance and versatility vs a X86_X64 NUC as a home server.

The ticking timebomb lemons with reliability or design issues, will just die in the first 2-4 years like clockwork, but if they've already survived 6+ years without any faults, they'll most likely be reliable from then on as well.

That if a laptop is 6 years old it will only last 4 more years. Or that a Pi will last more than 10.
qsera 1 hour ago||
If it is a generic laptop, yes. 10 years is a stretch. Components used in the motherboard are probably not high quality enough to last more than 10 years. A manufacturer does not have an incentive to put high quality stuff (that is probably costlier) in a laptop who's only selling point is cheap for the "features", and not reliability or longevity..

One might get lucky with such a laptop, but I won't count on it.

Again, is that just a feeling, or do you have some data to actually show this. In my experience even old basic Acer laptops easily last more than 10 years, probably without the battery and married to the charger forever now, but they will work fine. But I don't go on the internet and tell everyone laptops last most than 10 years just because I know of a few Acers lasting that. Likewise, do you have any statistics on longevity of Raspberry Pis.

The Raspberry Pi probably still has the advantage of an actually robust firmware/software ecosystem? The problem with SBCs has always been that the software situation is awful. That was the Raspberry Pi's real innovation: Raspbian and a commitment to openness.

Fragmentation in the non-x86 world really hurts adoption. RPi presents a very well documented configuration that can be used as a target for development.

RISC-V is going through this exact same problem right now. All of the current implementations have terrible documentation, and tailoring Linux for each of these is proving to be difficult. All of these vendors include on-board devices that have terrible doc and software support.

I think this is a miss on what the Pi is: an experiment. Sure, it stood on the shoulders of other SFF boards that came before it - but it broke into the general computing landscape targeting makers and builders. If the AI hat doesn't work out, so be it. The use cases for this type of hat may yet to be seen. On one hand it may feel shortsighted to bringing hardware to market with no explicit use case, but that's part of the Pi brand.

As someone else mentioned: if the hat could efficiently be leveraged with the YOLO models on Frigate for a low volume camera setup that could be a nice niche use case for it.

Either way I hope the RPi org keeps dropping things like this and letting the users sort out the use cases with their dollars.

Nah, they released products better suited to what people were already using Pis for.

The Picos are great for the smaller stuff, new Pis are great for bigger stuff, and old Pis and Zeros are still available. They've innovated around their segment.

IMO this is a consequence of Raspberry Pi going for-profit and IPOing. Now they are incentivised to chase the same hype trains as every other public tech company. I can't see them having another "Raspberry Pi moment", those are too risky now.

That said, more options at the (relatively speaking) low end of the AI hardware market probably isn't a bad thing. I'm not particularly an AI enthusiast generally, but if it is going to infest everything anyway, then at least I would like a decent ecosystem for running local models.

> Not everything needs to be for everyone

I wouldn't dare suggest that. The RPi was never for everyone yet it turned out it was for many. It was small but powerful for the size, it was low power, it was extremely flexible, it had great software support, and last but not least, it was dirt cheap. There was nothing like that on the market.

They need to target a "minimum viable audience" with a unique value proposition otherwise they'll just Rube-Goldberg themselves into irrelevance. This hat is a convoluted way to change the parameters of an existing compromise and turn it into a different but equally difficult compromise. Worse performance, better efficiency, adds cost, and it doesn't differentiate itself from the competing Hailo-10H-based products that work with any system not just RPi (e.g. ASUS UGen300 USB AI Accelerator).

If you aren't ditching the laptop you aren't miniaturizing, just splitting into discrete specialized components.

It is neat, and at 32GB it might be useful.

Almost nothing useful runs in 8.

This is the problem with this gen of “external AI boards” floating around. 8, 16, even 24 is not really enough to run much useful, and even then (ie. offloading to disk) they're so impractically slow.

Forget running a serious foundation model, or any kind of realtime thing.

The blunt reality is fast high memory GPU systems you actually need to self host are really really expensive.

These devices are more optics and dreams (“itd be great if…”) than practical hacker toys.

You can run some models pretty decently using CPU inference only, things like Gemma 3 that are built for exactly that use case or some tiny speech to text models via llama.cpp that I have tested out (not so good). Although not the best for "heavy" tasks, if you just need a decent text generator that can produce more or less sensible, generic output you are good to go.

It's more about demonstrating what's possible on a Pi than expecting GPT-4 level performance. It's designed for LLMs that specialize in tiny, incredibly specific tasks. Like, "What's the weather in my ant farm?" ;)

The vision processing boost is notable, but not enough to justify the price over existing HATs. The lack of reliable mixed-mode functionality and sparse software support are significant red flags.

Surely with this hat you don't have any access to any GPIO?
