arXiv:2605.09165v2 Announce Type: replace-cross Abstract: Looped language models repeat a set of transformer layers through depth, reducing memory costs and providing natural early-exit points at loop boundaries. However, looped models do not scale as favorably as standard transformers with unique layers. We compare standard and Mixture-of-Experts (MoE) transformers, with and without looping, and find two main results. First, we find Looped-MoE models scale better than the standard baseline while dense looped models do not. We trace this to routing divergence between loops: in Looped-MoE model
This research emerges as the AI frontier pushes for increasingly efficient and scalable architectures, making optimization of foundational models a key area of current innovation.
The findings suggest a path to significantly reduce memory costs and improve the scaling of advanced language models, which is critical for their broader application and power consumption.
This research provides a new architectural direction for highly efficient language models, particularly by highlighting the unexpected scaling benefits of Looped-MoE over dense looped models.
