The other advantage of the local GPU is that you are not feeding your data into cloud providers. I'm not sure how much you can really trust Anthropic and OpenAI not be improving their models based on your input.

You can turn off training with codex an gemini. Not sure about Anthropic.

It doesn't cover risk. If one or more gpus dies, who pays for it? If you rent, you are guaranteed to be insulated from this risk. But owning, you might not have the best return policy from the vendor. And if you are actually at fault for breaking it, they have every right to deny a return. Or if your apartment is burglarized or catches fire (possibly from overloading the circuit) you are out the entire investment.

In the article, he wrote "I tried to insure it under my renter’s insurance policy. They didn’t like that. I had to get business insurance to cover it.“, but he didn't say how much it cost, either.

Privacy and offline operation are valuable or non-negotiable in some cases, but the difference is pretty categorical between what can run on a single card and what can run on a DGX GB200 NVL72 cabinet. Doesn't mean it's not worth seeing how far local models can be pushed. Not every problem needs a senior engineer.

I know it's one of those "if you have to ask" situations, but curiosity got the better part of me. Here's the search assist response: "The DGX GB200 NVL72 AI server costs approximately $3 million per unit. This system includes 72 Blackwell GPUs and 36 Grace CPUs, making it one of the most powerful AI servers available." The search assist actually credited a source used with: https://www.tweaktown.com/news/98292/nvidi…

By comparison, the Colossus 1 data center had 32,000 GB200s (as well as 150,000 H100 GPUs, 50,000 H200 GPUs), and they are bringing another 110,000 GB200s online (although this might be Colossus 2?)

There are bigger data centers than Colossus 1 around too.

There is a reason NVidia is the most valuable company on the planet.

I built a very similar server myself [0] with a similar setup. I run different models for different purposes, but the primary one currently is kimi 2.6. I run kimi as the orchestrator model and then qwen, Gemma and others for specific tasks (sometimes loaded dynamically based on the task at hand), all exposed through the pi harness. I also use Hermes for some personal repeated tasks which connects to the same models, hosted on my local Mac Studio.

I am not even going to pretend that this is financially reasonable option. I simply wanted to have a local models. Maybe down the line, as cloud models become less subsidized, I might benefit from having a local setup, but for now, it wasn't the most prudent financial decision.

But one big benefit is that I never have worry about my account being randomly banned nor I have to worry about running out of quota. I still use codex and opus for some specific tasks, but as tools are improving, I need them less and less.

I'm not entirely sure what your point is here; me asking for humans to give an opinion does not preclude me from also asking AI.

I was just making a correction based on what you said. "AI is cool but it's not going to have all the good and bad experiences that humans have had with different motherboards." AI will have more access to experiences than you'll find here.

It actually won't have "had" any experiences though. Yes, it can aggregate stuff from blog posts and reviews and marketing material. That's hardly the same thing.

> The mentality shift of renting vs. owning the gpus is huge. When renting, each experiment costs money and I had to ask myself is it worth it. When owning, it feels like not running experiments is costing me money.

I feel like there is some very deep generalizable wisdom buried here.

In the last year, I have bought an M3 Ultra Mac Studio with 512 GB, a Macbook Pro M5 MAX with 128 GB and an RTX 6000 Pro. I have spent around $25k so far, not including electricity. I figured worst case scenario I can sell them in the next year and only take a haircut as opposed to losing my entire investment. In comparison to just spending for tokens, the tokens would have been much cheaper and much much faster. I'v…

This is, sadly, obvious and inevitable in retrospect. The two major drivers of inference costs are GPUs and electricity. You can't get cheaper GPUs, but you can make existing GPUs not sit idle, and you do that by utilizing them 24/7, processing user B's request when user A is thinking, and handling many requests in parallel, neither of which you can do as an individual. You can get cheaper electricity... by moving, a…

It also doesn't help that they probably sell tokens below cost.

Historically it was not uncommon for beds to be rented out to multiple people.

See military submarines, for a modern version.

It is unfortunately still common practice among irregular agricultural workers in many parts of the world (I’m Italian so I definitely remember news about busts in southern Italy)

Either I don't understand the used apple market.. or I agree this is crazy. Someone spends $25k on new hardware, waits a year, and expects to sell it for $23k? Unless the ram issues save him, and cost of new goes up, I don't see how that was going to work.

Apple products have had relatively high resale for a while. Only losing 8% in a year is probably extra unusual, and 1-year-old wasn't really ever the sweet spot, but a "sell used privately after a few years, roll onto the new one" has been a relatively common play. Doing this particular one is definitely expecting the market squeeze to continue. "Worst case" is back to more "normal" depreciation. Where I'd expect to…

What you describe is something people with enough to make the first purchase and eat the cost when it breaks have been doing for years e.g. with cars. People on the lower end of money scale tend to use products for well over their economic lifetime saving way more and buying a cheap replacement if it breaks. Notable exception as stated being phones for some reason as it likely is a status symbol for more people in a [insert preferred external sexual characteristic] measuring contest.
