Yeah. And chess is perfect for a mobile. So all of those things were true. Then what happened was we have a person internally we love. His name is Tyler, Tyler Murphy. He's been here forever and he's really, he's started a lot of really our major initiatives. Tyler came to me and he said, I want to do chess. And, you know, I went through the list and I'm like, it satisfies everything that we want.

Let's do this. And so Tyler started working on chess with this other guy, Edwin, two very long-term employees, long-time employees of Duolingo. And neither of them is an engineer. Tyler's a designer and Edwin's a product manager. And what was amazing about chess is all other projects that we started in the past, we needed to put like a team on them with engineers and everything.

In this case, we did not. We just let them, we're like, okay, you know what? At the moment, I have no engineers to give you. You figure it out.

And what they did is they basically started messing with large language models. And for the first several months, they made an entire chess course through large language models, no engineering required. And they came to me with prototypes that they had made, even though these people are not engineers, of like how to learn chess on Duolingo.

And it was just the two of them, and it took them a few months. Now, of course, by now, we're about to launch. We now have a team that has actual engineers to put the stuff in the app, et cetera. But for the first several months, normally, we would have put a much larger team. It would have taken us much longer.

But this really is a case that with large language models, we were able to do this really fast, actually.

That is what happened. Again, I do want to emphasize, we now have engineers and a team and everything. But this is what happened for the first, call it, six months.
