"He is not a YouTuber"... what?

Jeff's had a pattern of embellishing controversies, misrepresenting what people say, and using his platform to create narratives that benefit his content's engagement. This is yet another example of farming outrage to get clicks. I don't understand why people drool over his content so much.

I thought the conclusion should have been obvious: A cluster of Raspberry Pi units is an expensive nerd indulgence for fun, not an actual pathway to high performance compute. I don’t know if anyone building a Pi cluster actually goes into it thinking it’s going to be a cost effective endeavor, do they? Maybe this is just YouTube-style headline writing spilling over to the blog for the clicks. If your goal is to play…

I did some calculations on this. Procuring a Mac Studio with the latest Mx Ultra processor and maxing out the memory seems to be the most cost effective way to break into 100b+ parameter model space.

You could try getting a DGX Thor devkit with 128GB unified memory. Cheaper than the 96GB mac studio and more FLOPs.

Also cost effective is to buy used rack mount servers from Amazon. They may be out of warranty but you get a lot more horsepower for your buck, and now your VMs don’t have to be small.

Putting a retired datacenter rack mount server in your house is a great way to learn how unbearably loud a real rack mount datacenter server is.

ahah and pricey power wise.

Currently the cloud providers are dumping second gen xeon scalables and those things are pigs when it comes to power use.

Sound wise its like someone running a hair dryer at full speed all the time and it can be louder under load.

I really don’t understand the hype over raspberry Pi.

It’s an overrated, overhyped little computer. Like ok it’s small I guess but why is it the default that everyone wants to build something new on? Because it’s cheap? Whatever happened to buy once, cry once? Why not just build an actual powerful rig? For your NAS? For your firewalls? For security cameras? For your local AI agents?

Yeah... Looks like can get about $1/hr for 10 small VMs, ($0.10 per VM). So for $3000, that's 3000 hours, or 125 days, (if just wastefully leave them on all the time, instead of turning them on when needed). Say you wanted to play around for a couple of hours, that's like.. $3. (That's assuming there's no bonus for joining / free tier, too.)

You can rent a beefy vm with an H100 for $1.50 / hr I regularly rent this for a few hours at a time for learning and prototyping

If you assume that the author did this to have content for his blog and his YouTube channel, it makes much more sense. Going back to the well with a "I regret" entry allows for extra exploiting of a pretty dubious venture.

YouTube is absolute jam packed full of people pitching home "lab" sort of AI buildouts that are just catastrophically ill-advised, but it yields content that seems to be a big draw. For instance Alex Ziskind's content. I worry that people are actually dumping thousands to have poor performing ultra-quantized local AIs that will have zero comparative value.

I don’t really get why anyone would be buying ai compute unless A) to your goal is to rent out the compute B) no vendor can rent you enough compute when you need it C) you have an exotic funding arrangement that makes compute capex cheap and opex expensive. Unless you can keep your compute at 70% average utilization for 5 years - you will never save money purchasing your hardware compared to renting it.

Data privacy and security don't matter? My secondhand RTX 3060 would buy a lot of cloud credits, but I don't want tons of highly personal data sent to the cloud. I can't imagine how it would be for healthcare and finance, at least if they properly shepherded their data.

For most people, no, privacy does not matter in this sense, and "security" would only be a relevant term if there was a pre-existing adversarial situation
