Facebook SilverTorch: "Index as Model" Retrieval Paradigm

Meta Engineering published SilverTorch (May 26), a new retrieval architecture for recommendation systems that treats the index itself as a learned model rather than a static lookup structure. While aimed at recommendation systems, the underlying pattern — embedding retrieval intelligence into the index rather than the query layer — has direct implications for RAG system design. Worth reading for anyone architecting high-scale retrieval pipelines.
