Latent Space: The AI Engineer Podcast · Inside the Model Factory — Eiso Kant, Poolside AI · 23 Jul 2026 podcast

I want this to be

you know, shuffled in a certain way and your training job can start while the rest of the data is even still materializing.

Also, what it does is because all of this underneath, so for us, we treated the data layer underneath as like an immutable data layer.

And that was really important.

Like experiments as code, immutable data later means that you can always go back and understand literally down to the single token at which cursor it went in on which version of the code.

And it took us, I have to admit, like the first year of Poolside, we understood that engineering had to get great.

But we didn't understand yet that this is ultimately in support of a good, rigorous scientific progress.

We were a very small number of people, so a lot of it was YOLO ideas and YOLO runs.

And we built great infra for the YOLO runs, but once we realized that we treated data as immutable and code as always version, and you could always track and trace every experiment end-to-end perfectly, you could repeat everything perfectly, right?

You had perfect reproducibility.

I can still reproduce runs from two years ago if I wanted to, right?

It actually enables the scientific progress, like the scientific process.

And I think that took us probably about a year, year and a half into the company to figure out.

We also had some great hires, like our co-head of applied research, Nikolai, who joined us from Yandex.

We've been working on language models since like the early 2020s.

I think brought that into the company of like, hey, we want to have even more rigor

And then once we kind of had the combination of like increasingly more capable platform that allowed people to do more but had this immutability, we were able to start actually, okay, every experiment is truly an ablation.

We truly need to understand it.

And I think we became much more scientifically rigorous in the last couple of years and the infra underneath enabled it.

And then there's just fun stuff like.
