arXiv:2606.08327v1 Announce Type: cross Abstract: Standard transformers apply self-attention uniformly at every layer and token, regardless of whether the input requires dynamic cross-token interaction. We propose CHIAR-Former (Chiaroscuro Attention), a 4-layer hybrid transformer that routes each token to one of three operators - DCT spectral mixing, RBF kernel mixing, or full self-attention - based on per-token spectral entropy, a theoretically justified complexity signal. Through systematic ablation on WikiText-103, we discover routing collapse: the router consistently rejects RBF in favour
The increasing computational demands of large transformer models are driving innovations in efficiency, with researchers actively exploring methods to optimize compute spending.
This development proposes a method to significantly reduce the computational cost of transformers, potentially making advanced AI more accessible and scalable.
The standard uniform application of self-attention in transformers could be replaced by more dynamic, efficient, and context-aware routing mechanisms, altering future AI model architectures.
