The reason why we're building our own big models is because we want to be able to like build exactly what we want, right?

And none of the other models in the world are sort of exactly what we want.

If they're open source, then you can take them

And you can fine tune them in different ways, but you still have to deal with the model architectures.

And, you know, they make different size trade-offs around that affect the latency and inference cost of the models.

And it's like, okay, the scale that we operate at, that stuff really matters.

Like we made...

the llama scout and maverick models certain sizes for a specific reason because they fit on a host and we wanted certain latency especially for the voice models that were that we're working on that we want to just basically have purveyed and and be across everything that we're doing from the glasses to all of our apps to the meta ai app and and all this stuff so um

So I think that there's a level of kind of control of your own destiny that you only get when you build the stuff yourself.

That said, there are a lot of things that like AI is going to be used in every single thing that every company does.

When we build a big model, we also need to choose which things, which use cases internally we're going to optimize for.

So does that mean that for certain things, we're not going to think that like,

okay, maybe Claude is better for building this specific development tool that this team is using.

All right, cool, then use that, fine, great.

I don't think, we don't wanna fight with one hand tied behind our back.

We're doing a lot of different stuff.

You also asked would we maybe, would it not be important because other people are doing open source?

I don't know, on this, I'm a little more worried because I think you have to ask

For anyone who shows up now and is doing open source now that we have done it, there's a question which is, would they still be doing open source if we weren't doing it?

And I think that there are a handful of folks who see the trend that more and more development is going towards open source.
