As of late 2025, Meta has invested over $14 billion to acquire a near-majority stake in Scale AI. Scale’s infrastructure is now being used to train Meta’s next-generation “Mango” (video) and “Avocado” (text) models, with Scale’s founder Alexandr Wang overseeing the project.
What is RLHF and does Scale AI do it?
