A lot of the other companies are selling AI as a service. Meta hasn't really been in the space of selling a raw service in that way. However, they are at a center point of human interaction that few can match. In this space, it is how they can leverage those models to enhance that and make that experience better that can be where they win. (Think of, for example, giving a summery of what you've missed in your groups, letting you join more and still know what's happening without needing to shift through it all, identifying events and activities happening that you'd be interested in. This will make it easier to join more groups as the cost of being in one is less, driving more engagement).
For facebook, it isn't the technology, but how it is applied, is where their game starts to get interesting.
When you give away the tooling and treat it as first class, you'll get the wider community improving it on top of your own efforts, cycle that back into the application of it internally and you now have a positive feedback loop where other, less open models, lack one.
