“the LLM recommender will become one of the biggest consumer applications of AI”
Meta's head of Recommendations Research argues that recommender systems obey the same power-law scaling curves as LLMs, and that the industry is at a very early point on that curve. He positions LLM-powered recommenders—already serving over a billion daily active users across Instagram and Facebook—as the sleeper giant of consumer AI. Semantic identifiers and generative search, ideas he introduced at last year's AI Engineer, have since moved from research into production at YouTube, Spotify, and DoorDash, signaling broad industry adoption.
