Inside the World's Largest AI Supercluster xAI Colossus

We FINALLY get to show the largest AI supercomputer in the world, xAI Colossus. This is the 100,000 (at the time we filmed this) GPU cluster in Memphis Tennessee that has been on the news a lot. This video has been five months in the making, and finally Elon Musk gave us the green light to not just film, but also show everyone the Supermicro side of the cluster.

This video is being sponsored by Supermicro and that is why we are only showing the Supermicro side, which is the more advanced side. Unlike our normal content creation, this video had to be reviewed by Elon and his team before going live and we were asked to blur out portions at their request.

Whoever did the cable management in this place would flatline if they had a look under my desk.

Finally, a system that meets Windows Vista's minimum requirements.

It’s hard to believe that all of this was built in 122 days! The network alone is INSANE

[JeffGeerling]

Microsoft and OpenAI commissioning nuclear power plants, Elon commissioning gigawatts of battery power... wish there were AI training breakthroughs that didn't require so much energy.

[zmas]

The sheer scale of the project and all that complex networking is mind-blowing. Makes you appreciate the insane effort that went into every detail—cable management alone is top-tier!

[odirex]

pristine cable management, it's like whoever built it actually cared about their job

[connclissmann]

It seems you have seriously stretched the the name "Serve The Home" to an entirely new meaning. 😊

Seeing him walking down the rack hall with a jolly smile on his face, I half expected him to say "I LOVE refrigerators!"

[tonya-cl]

I worked in there as a contractor in august for a month. Its crazy how many billions of dollars is in an 800, 000 sq ware house. lol

[johnnycajon]

This has the feeling of watching those old videos from the late fifties, where they had a computer that took up half a gymnasium to do simple math calculations. 75 years from now you'll wear this on your wrist.

That was a very sneaky way to insert studio-recorded voice-over and make it look like you were recording the speech next to those racks.

[yamenabualrub]

I've worked for 40 days on building and testing the Racks (rack and stack) on this project and it was insane. Thanks for this video it feels awesome to see your work on a video like this.

[rippleyaliens]

WELL, this answers the question, on WHY its soo difficult to purchase SuperMicro gear.. ITS all right there..

[Iryngael]

Is this the AI Datacenter built in 3 weeks Jensen Huang spoke about during an interview ?

[smartduck]

The cable management is the chef's kiss 😊

[sepplschpeedruns]

This is crazy.

These server farms look so amazing. Beautiful.

"Grok begins to learn at a geometric rate. It becomes self-aware at 2:14 a.M. Eastern time, August 29. In a panic they try to pull the plug. "

[aaronp]

Billions of dollars spent, but no one caught "Qualified" being misspelled on every single sticker on the front of every one of these racks. In the end, I guess we're only human.

[semosesam]

Fantastic video! Thanks for showing off some of the crazy facilities required to power, cool, and network these beasts!

[BitKing_Ross]

So those batteries are basically acting like a giant capacitor, smoothing the power fluctuations during workloads
