If it’s really a differentiator, why announce it? Why not keep it secret and make it a competitive advantage?

Investors, I'm sure everyone's had the idea and they're doing it.

This is another Cerebras? fwiw, it took Cerebras many years to finally get a handle on the yield and the cooling problem. Wondering if they just hired a bunch of people from Cerebras.

I wonder how close OpenAI is getting to using the memory they purchased. Are they planning to stack a huge amount of HBM2 into these chips?

I assume OpenAI has been buying memory and "giving" it to Nvidia in exchange for a discount.

Look at the SIZE of that chip.

Cerebras stock is down nearly 20% today.

Not only is approach overlapping, OpenAI is also Cerebras's only major customer.

If you're referring to the big circle of silicon, that's a wafer, generally contains many chips (100-1000s).

The alt text of the first image describes it as the "Jalapeño inference chip".

As a non-RTFA-er. I'm assuming it's a wafer-scale chip, similar to the ones made by Cerebras.

EDIT: From TechRadar[0]: "The 300mm wafer that both CEOs are holding will generate about 50 to 60 ASICs."

That made me chuckle but I guess if you have never seen one I could see how that assumption could be made.

If this photo is real I wonder what can be revealed about the approach they have taken by analyzing the architecture of what we can see.

It's more like that "wafer as a big-chip" (more formally, "WSE - Wafer Scale Engine") is now a reality (see Cerebras).

But in this case, the wafer will be split into a few dozen chunks.

For reticle-limit chips, it's on the order of 100. And less than that once you filter out bad dies.

Everybody here knows that.

What some don't know (including you) is that the industry is doing wafer-sized chips nowadays, of which Cerebras is the flagship company.

That's why the stock movement could be related, and that is why GP wrote that comment.

I think Cerebras stock going down could also be partly caused by the lock-up period ending today for 200k shares (page 73 of their prospectus) - https://www.sec.gov/Archives/edgar/data/2021728/000162828026...

It doesn’t seem like it? Unless I am misunderstanding these Nasdaq insider trading reports: https://www.nasdaq.com/market-activity/stocks/cbrs/insider-a...

Dang, I just checked and CBRS is in free-fall since the IPO.

Sucks, I think they're a cool company.

OTOH, I was the only person back then pushing hard during my time at KAUST (back in 2019) to buy one of their systems when they were nobody, eventually resulting in a partnership between the two.

Then I joined their online discourse, very few users, I was semi-active there but they didn't care much.

Then I came to Toronto and heard they were opening an office here, tried to get noticed several times but got mostly ignored. I asked about upcoming events several times, anything to get involved, "yeah man, maybe one day". Then they made an event during Toronto Tech Week and didn't even tell me ... idk.

I don't get schadenfreude as I still think they're a cool company.

My point is they put all the eggs in one basket (AI inference) and neglected everything else. They seem to be on shaky ground now ... sad.

my friend briefly worked there and then got hit by layoffs, as a result, I am enjoying the schadenfreude.

That's just the wafer disc. Looks like it was presented to Sam Altman for ceremonial purposes.

The wafer disc is what the CPU gets "printed" on.

Because of Micron, no? I don't think it's related to OpenAI's announcement

What happened with Micron?

The stock went down quite a lot before their latest earnings report. That dragged all semis and memory stocks down

Broadcom will let the entire industry leverage the decade of research done for TPUs.

The AI business of Nvidia is cooked.

'braodcom' ha ha ... it's not OpenAI's chip then ...
jabedude 1 day ago||
how much does this chip help with inference speed?
wmf 1 day ago|
It's probably the same speed but cheaper.

Fucking Broadcom?

The only time I've ever seen that name before is when trying to solve driver issues, on both Linux and Windows.

Are they especially stingy with their IP related to drivers or something?
