appreciate the work Dwarkesh Patel does with interviews like this.

Jane Street showed the inside of their AI training data center in Texas.

They have 4,032 gpus.

56 racks.

8,000 km of fiber

Liquid cooling runs through every server.

Air cooling cannot handle the heat anymore.

The origin story really got me.

Ron Minsky who co heads technology there said it started with six dell boxes stacked at the end of a desk row.

They called it the hive.

Trading systems sat out in the room with the traders.

They wanted to unplug them fast if something went wrong.

At one point someone vacuuming the office unplugged a live trading system in the middle of the day.

From that simple start to trades under a hundred nanoseconds.

Twenty years later.
