What they want to know is how can we prevent it?

What do we need to do now to change the future?

And there, what you really need is causal mechanism.

You need a model that can actually reason about causal mechanisms and counterfactuals.

So the kind of data that we care deeply about is a lot of randomized control trials.

We actually run a lot of A-B testing.

We show the models.

Imagine people have done this versus that.

This is how their behaviors will actually change.

And that becomes a core part of our training asset.

So this is actually the data collection that goes beyond observational data that Simile collects.

Data is an important piece of simile, for sure.

My fundamental thesis here is for AI companies of this generation, you need to have an interesting data strategy that's going to be defensible.

And for us, really the data collection challenge comes from two angles.

One is actually sourcing people.

Sourcing people here is a little bit different than what other language model companies might consider to be their people or their population.

We don't go after these expert programmers or expert scientists.

We go after people like us, everyday people living their everyday life.

But what we care about is are they representative?
