Netflix pitted an LLM against its own feature-engineered recommender — and the LLM won

Netflix has developed a new recommendation system called GenRec, which utilizes a large language model (LLM) and has outperformed its previous feature-engineered system by 1.6 percent in offline ranking quality. This new system requires significantly less training data and is more adaptable to new content formats like games and live programming, though it still requires a separate component to handle hallucinations and ensure only existing catalog items are recommended.
