Okay.

Starting from the evaluations.

So evaluation is something like people often overlook in the robotics.

But if you are training like a robot in Vodafone, you have to know how well it works.

And that is the only source of information for you to iterate.

Okay.

So what I mean by evaluation is you'll be able to understand for this specific checkpoint,

How well does it perform?

Does it perform, for example, 95% of the time or 99.9% of the time?

And the key criteria people use in industry is how long does it take?

How long in work time does it take for you to distinguish between a checkpoint that is 90% from a checkpoint that is 92 points?

And if you only do that in the real environment, that's just take so long.

for you to do the distinguishments.

And you really think about also the robotic evaluations right now people are doing in the real environments.

The iteration speeds is multiple orders of magnitude slower than iterations of those language models.

So not only is like the robotic tasks very varied, very diverse.

Exactly.

So not only is it slow, it's dangerous, it's costly, but at the same time, the speed is also like multiple hours of magnitude slower.

So some of our clients actually need this digital environment.

that can be used to evaluate their robotic systems.
