The real issue is that housing is heavily underweighted in the cpi basket. How many people do you know that are only spending 12.9% of their after tax take home on housing, water a…

Wouldn’t say never harder, but it’s been pretty flat. https://fred.stlouisfed.org/series/FYFRGDA188S

My girlfriend loves it. She’s an immigrant from Kazakhstan and apparently the Kazakh community on Threads is very active. Reminds her of home.

if you bought a nvidia h100 at wholesale prices (around $25k) and ran it 24/7 at commercial electric rates (lets say $0.1 per kwh), then it would take you over 40 years to spend th…

Actually since the qe to fix 2008 foreign investors/governments cut down on bond buying. Treasury has foreign bond holdings up about 2T since 2014 and current account deficits sum …

Or maybe a lot of it can't deliver returns in line with the current price. The world realizes that and stops sending us stuff for those investments. Then we're stuck with limited m…

It is tracked! there are a few different numbers. by the BEA: https://fred.stlouisfed.org/graph/?g=gX0f by the treasury: https://ticdata.treasury.gov/resource-center/data-chart-cen…

1800 on the h100s is with 2/4 sparsity, it’s half of that without. Not sure if the tpu number is doing that too, but I don’t think 2/4 is used that heavily so I probably would comp…

I remember reading that it’s too hard to get good memory bandwidth/l2 utilization in the fancy algorithms, you need to read contiguous blocks and be able to use them repeatedly. Bu…

I guess it's hard to know how well this would compete with integrated gpus, especially at a reasonable pricepoint. If you wanted to spend $4000+ on it, it could be very competitive…

I think we don't really disagree, I just think that this shape isn't really a gpu its just a cpu because it isn't very good for graphics at that point.

For ai inference you definitely have other options, but for low end graphics? the lpddr that apple (and nvidia in grace) use would be super expensive to get a comparable bandwidth …

GDDR isnt like the ram that connects to cpu, it's much more difficult and expensive to add more. You can get up to 48GB with some expensive stacked gddr, but if you wanted to add m…

One day is doing some heavy heavy lifting here, we’re currently off by ~3-4 orders of magnitude…

The real reason is that it's basically impossible to produce a cheap new car that is a better deal than a Toyota with 80k miles on it.

For decode steps it depends on the number of inputs you run at a time. If your batch size is 1 then it runs in line with active params, then as you get to like batch size 8 it runs…

Not just gpus, the k20 was at 3.9 Tflops (fp32) and the new iPhone is at 4.3 (fp16). If you don’t need the precision it got passed by the phones

You’d get better perf training on a current gen phone than that gpu, but it probably functions

Are you one of the authors?

I feel like that blogpost was almost just ragebait for ai researchers. It goes between calling not including the +1 an error (which to me implies it would improve training losses, …

My hypothesis for why this works that it mitigates the downsides of rope to eli5: rope is the modern strategy used to give information to the model about how far a query and a key …

I think they mitigated the extra memory/compute from this by using half the number of overall heads and doubling V and O. Without actually checking the math I think it should be eq…

I wonder how much of the value here is from canceling out the positional noise rope produces. I would love to see a table comparing an alibi version of this to an alibi baseline in…

Their numbers are for a single input, I assume the throughput is much higher given the prices they are quoting and the cost of a single cs3.

On die communication isn’t free, a lot of things here are sequential and within matrix multiplies the cores have to transfer output and mem loads have to be distributed. It’s reall…
