Colossus 1 is the GPU farm that powers the world's most powerful AI: Grok 4
Elon is working towards bringing Colossus 2 online in a few weeks with half a million GPUs. And building something like this in a few weeks is insane

230k GPUs, including 30k GB200s, are operational for training Grok @xAI in a single supercluster called Colossus 1 (inference is done by our cloud providers).

At Colossus 2, the first batch of 550k GB200s & GB300s, also for training, start going online in a few weeks.

Gonna need a few more windmills

But seriously... the power needed for these training centers is enormous. Colossus 1 and 2 are in Tennessee. Colossus 1 consumes .7% of Tennessee's power output, and Colossus 2 will consume 3.2%.

xAI has temporarily deployed 17-35 methane gas turbines in South Memphis to generate 35-72 MW. Long term, xAI is funding a $24 million substation to provide a stable 150 MW from MLGW, expected to be operational by late 2025.

Also, xAI has purchased an entire overseas gas-turbine power plant to be shipped to Memphis, bypassing local grid bottlenecks. This move aims to provide a dedicated power source for Colossus 2, though specific details on capacity and timeline are not fully disclosed.

Ad Nauseum:

What could go wrong?

I don't understand it. Therefore I will automatically assume the worst possible outcome. I might even protest.

I saw where GROK4 aced the AIME test.


"The median AIME score is around 6, with the top 1% scoring 13 or more.
The exam features only 15 integer-answer problems, each requiring a unique insight or creative solution.
Getting all of them right is a truly exceptional achievement."

Invest in utilities and substation EPC contractors.

And Grok 4 will still go full ****** at random because it is learning off all the dumbassary people post on Twitter.

Irony.

The tech sector, who was completely aligned with the Obama administration and colluded heavily with the dems to influence both the 2016 and 2020 elections, will be the end of any significant move towards green energy (at least in its current options). They showed up big for Trump this year for a reason.

They could only go the way of windmills, solar panels, and unicorn farts for so long.

Getting old sucks but one part of getting old that doesn't suck is knowing I don't understand what the hell you're talking about and I don't really need to.

Looks like we need a healthy investment in nuclear power to help run this stuff. Alas, my desire for expanded nuke power for complete energy independence is but wishes and dreams.....

All the more reason everybody needs to clear the way for nuclear to take over.

SSMR's would be a lot more efficient for power production.

Not a fan of the headfirst dive into the AI crap, but if it at least pushed us out of the stupid when it comes to nuclear, especially Gen4 SSMR's....then it may be worth it.

Seems to me that the logical power solution for these places would be to build gas power plants in the Permian Basin and then locate their facilities there. There is more than enough gas flared off for lack of a market to handle a bunch of these facilities, and they would be reliable baseload plants, not intermittent supplies requiring back up.

Or they could be what actually gets us off of high center and back into actually promoting and using the only actual "green" energy out there - nukes.

I'm all in on nuclear energy. No argument here.

Water might be a mitigating factor. Data centers use a crap ton of water for cooling - 1mgd or often more. I'm not super familiar with the water situation in the Permian, but it's always been known to be hot and dry up there, which is why nobody voluntarily goes there. Well, one reason why anyway.

Career field in that industry is exploding

And the fact that nuclear is the only viable way to provide enough power for these data centers means we will FINALLY get nuclear power as a meaningful part of our energy generation.

the irony. for tech bro dems to get their way and have major AI be a possibility nuclear power will be a necessity

UTES and NLR folks….

I for one welcome our new AI overlords.

My company has been getting into some of the data center stuff, it is crazy on how quick they are moving with everything. From PO/contract agreement until the servers being connected is 6-8 weeks sometimes.

Those wells also produce salt water, which I would imagine could be used by data centers after RO treatment. Might be another win/win solution. Wouldn't be the cheapest water, but it might make more sense than building more wind turbines.

thank god i am not the only one who has seen this outcome/ movie. no one knows where this road leads but it isn't all rainbows and unicorns with AI.

We are already beyond dependent on our power grid.

What happens when literally everything becomes dependent on AI, which is completely dependent on huge sources of uninterrupted power. Seems like our vulnerability to grid failure becomes 100% existential.

AI my end up killing us in an unpredicted way

Anybody remember Colossus: The Forbin Project book and movie from circa 1970. Wonder if project named after that.

What happens when the AI watches terminator and thinks that sounds like a good idea.

It wins.

Here's to legal immigrants!

That's not a bad thing. It will remember all the terrible things libs did to them.

These AI data centers are going to be powered off the grid. There is no way our AI overlords are going to share their power with the plebes.

Can you imagine ERCOT having to shed load while leaving these data centers running? That would be a political nightmare that the AI providers will want to avoid.

Elon has already confirmed that xAI is using Tesla's visual training data

Insane that they can get everything racked, stacked, an cabled in that amount of time, much less have it operational.

These type of builds usually take a year or more as parts begin to arrive.
