A new research paper explores the interplay between pretraining and retrieval in language models, investigating how scaling model capacity and pretraining data affects retrieval gains. The study found that retrieval benefits are heavily front-loaded, with a significant portion of improvement achieved early in model parameter scaling. Performance gains from retrieval are objective-dependent, with smaller models showing better perplexity and larger models achieving higher accuracy. Notably, retrieval from previously seen data retains most of its effectiveness, suggesting a strategic partitioning of data for internal knowledge and external access in language model design. AI
