xAI built a supercluster in 19 days

👋 Good morning/evening (wherever you are). It’s Tuesday.

On a recent episode of Open Source with Brad Gerstner and Clark Tang (filling in for Bill Gurley), Nvidia CEO Jensen Huang praised Elon Musk’s vision and discussed xAI’s Memphis supercluster, reportedly built in just 19 days.

Jensen Huang said:

“Never been done before. xAI did in 19 days what everyone else needs one year to accomplish.”

“That is superhuman. As far as I know, there’s only one person in the world who could do that. Elon Musk is singular in his understanding of engineering, construction, large systems, and marshaling resources.”

OK let’s keep going ↓

It’s very addictive…

Check out the Tesla clip (I have more, but this one was pretty cool).

Watch the video. Posted on LinkedIn.

🧠 Thought starters

Yesterday I mentioned OpenAI's model earning gold at the Math Olympiad.

But the most interesting part wasn’t the score. It was what happened on Problem 6.

Apparently, the model knew it didn’t have the right answer.
