I'll settle with a much lower bar: an engineer that can tell the code the model generates is shit.

Most engineers can do that because it's way easier to find flaws in code you didn't write vs in ones that you write. My code is always perfect in my own eyes until someone else sees it.

From experience, most engineers can do neither.

I'm sure this question has been asked before, but why not launch a GPU with more but slower ram? That would fit bigger models while still affordable...

Because then you would have less motivation to buy the more expensive GPUs.

There's not much else (other than Epyc) in the way of affordably priced motherboards that have enough cumulative RAM. You can buy a used Dell dual socket older xeon CPU server with 512GB of RAM for test/development purposes for not very much money. Under $1500 (before adding video cards or your own SSD), easily, with what I just found in a few minutes of searching. I'm also seeing things with 1024GB of RAM for under…

PowerEdge R series is significantly cheaper if you already have an ear protection

yes, an R730 or R740 for instance. There's lots of used R630 and R640 with 512GB of RAM as well, but a 1U server is not the best thing to try putting gaming GPU type pci-express video cards into.

As other commenters have mentioned, the performance of this set up is probably not really great since there's not enough VRAM and lots of bits have to be moved between CPU and GPU RAM. That said, there are sub-256GB quants of DeepSeek-R1 out there (not the distilled versions). See https://unsloth.ai/blog/deepseekr1-dynamic I can't quantify the difference between these and the full FP8 versions of DSR1, but I've been…

Thanks a lot for the v2.5! I'll give that a whirl. Hopefully it's as coherent as v3.5 when quantized so small.

> I can't quantify the difference between these and the full FP8 versions of DSR1, but I've been playing with these ~Q2 quants and they're surprisingly capable in their own right.

I run the Q2_K_XL and it's perfectly good for me. Where it lacks vs FP8 is in creative writing. If you prompt it with for a story a few times, then compare with FP8, you'll see what I mean.

For coding, the 1.58bit clearly makes more errors than the Q2XXS and Q2_K_XL

Pcie lanes

I was about to correct you because this doesn't use PCIe for anything, and then I realized Arc was a GPU (and they support up to 8 per machine). Any idea how many Arc's it takes to match an H100?

I am reading from time to time about multi GPU solution and last time I found some real life information about this (it was two 7900 xtx) the result was that performance is the same at best often it is slower. So even if you manage to slap like 8 cheap cards onto motherboard, even if you would somehow make it work (people have problems with such setups), even if this would work continuously without much problems (crashes, power consumption) performance would be just OK. I am not sure if spending 10k on such setup would be better than buying 10k card with 40gbs of RAM.

Yeah, Nvidia doesn't have any incentive to do that and AMD needs to get their shit together at software side.

they absolutely can build gpus with larger vram, they just don't have the competition to have to do so. it's much more profitable this way.

The Q8 model is totally different?

My experience with quantizations is that anything below 6 is noticeably worse. Coherence suffers. I’ve rarely gotten anything really useful out of a Q4 model, code wise. For transformations they are great though, eg convert JSON to Markdown and vice versa.

I like Q5

The sweet spot for me
