Facebook/meta was very early in the “AI” space. They built lots of tools and models being widely used right now. Just look at their popular github repos, faiss, SAM, vision transformers, visual embeddings, core ML libraries, all very essential components of many ML systems.

Saying facebook “just” dove into AI is wrong, facebook has been there from the early days along with Google (and probably some more) in building the very foundations these stupid LLMs “thrive” on
