A new research paper explores how the embedding dimension in transformer models impacts the development of internal world models when trained on a simple sorting task. The study found that while models can achieve high accuracy with small embedding dimensions, larger dimensions lead to more consistent, robust, and interpretable internal representations. Specifically, the research identified two mechanisms: the attention weight matrix encodes global token order, and selected transpositions align with the largest adjacent differences in these encoded values. This work provides quantitative evidence for transformers building structured internal world models, suggesting that increased model size enhances representation quality beyond just end performance.
