Ask HN: What Llama model do Meta Ray Bans use?

They've recently introduced new AI features[0]. I tried them out at a Meta booth at a conference, and the marketing rep said they use Llama 2 as the model. But as far as I can see, Llama 2 has no vision capabilities (ofc theres the possibility of internal models)

Can anyone confirm what they actually use?
