Can Recommendation Ranking Models Follow the LLM Scaling Law? Introducing GPSD for Scalable Transformers

The paper analyzes why enlarging discriminative recommendation models leads to severe over‑fitting, proposes a two‑stage Generative Pretraining for Scalable Discriminative Recommendation (GPSD) that freezes sparse embeddings, and demonstrates across massive e‑commerce data, public benchmarks, and production A/B tests that the approach restores the classic scaling‑law behavior where larger models consistently improve performance.
