@iuditg @immortaldip GPU lead times are 6mo+ for hardware

@demian_ai ok but the rectangular panels still have to come from a cylindrical ingot, right? So it's just a question of at what step you cut the circle into rectangles?

@jasonschips that's what my 1U servers look like from years ago, 24 or more DIMM slots

Nassim Taleb: pick two people at random

If their combined height is 4.1m, it's basically 2.05 + 2.05.
If their combined wealth is $36M, it's almost never 18 + 18 - it's ~$1,000 and ~$36M.

Height lives in "Mediocristan," where the average tells you everything.
Wealth - and markets - live in "Extremistan," where one event dominates the whole picture.

Ruin there never comes from a string of bad days.
It comes from a single one.

Being right on average means nothing if one tail empties the account.

@mikesimonsen I think maybe you are right; the signage should be like “coffee in 117 seconds” because the impression is you are just going to stand around waiting

@3lectricBrawl On road trips it makes for a good garbage bin; it is not climate-controlled so you have to be mindful of what you put in there

Gemma 4 dropped a 12B.
I put it on RTX 5090 against its 31B sibling.

when you cut a model from 31B to 12B, what do you actually lose?

~ reasoning barely moves
GSM8K (math) 97.5 > 96.4 (−1.1)
ARC-C (sci reasoning) 97.6 > 94.0 (−3.6)

~ knowledge falls off a cliff
MMLU (world knowledge) 87.8 > 78.9 (−8.9)
HellaSwag (commonsense) 92.0 > 81.6 (−10.4)

~~~
parameters store facts, not thinking. the 19B you delete is mostly where the model kept its trivia and world-priors, cut it and recall collapses, while the reasoning machinery stays nearly whole.

a 12B reasons almost like its big brother. It just knows less.

122 tok/s vs 53 (2.3x faster generation), ~10GB instead of ~24, meaning that you get 20GB+ free on a 32GB card for long context or a second model.

so it depends of your workload:

reasoning / math / agentic loops = the 12B is nearly free

broad-knowledge Q&A with no retrieval = that's the one job worth paying for the 31B.

@CuriousTimL @edgecase411 It is likely to follow the car in front. If you're by yourself it will probably do the right thing.

[Alex Chekholko @RHAlexander]

"Gemma 4 12B delivers benchmark performance nearing our larger 26B model", so it's worse than 26B-A4B and strictly worse than 31B; I think it's great to improve efficiency, but I want smarter models, not smaller models that are not quite as smart as the existing ones.

@CKCapitalxx It’s great they already have revenue but how about profit?
