Understanding Generative Recommendation with Semantic IDs from a Model-scaling View
Researchers demonstrate that semantic ID-based generative recommendation systems hit significant scaling bottlenecks, while large language models used directly as recommenders show superior scaling properties and up to 20% performance improvements. This challenges current approaches in generative recommendation and suggests LLM-based systems represent a more promising path forward for recommendation foundation models.
