So I run all of our AI infrastructure at IBM Research, or my team does. But we have been, our main task lately has been, or since the last few years, has been training the Granite Foundation family of models. 

That was what gave me, hey, go build out our infrastructure. So we went out and built a large H100 cluster. And we did it ourselves, got the space, souped the nuts. 

It was a huge task. And what was large? This was 6,000 GPUs, but this was Dell's second XE9680 deployment, so it was Israel 1. 

We came out, and then they went up to Tennessee for that other very large cluster. Memphis. Yeah. So we had done it ourselves, and then we were speaking to Dell, we were talking to NVIDIA how they were going to deploy GB200 and how the rack was even going to work. 

And there was a lot of open questions. GPUs were melting back then.
