arXiv:2606.27449v1 Announce Type: new Abstract: Multi-head attention conventionally partitions the hidden dimension equally across all heads at every layer, enforcing an identical representational subspace dimension (dh = dmodel/h) throughout the models depth. In this work, we identify this uniform allocation as a fundamental structural bottleneck: due to their restricted dimensional space, early-layer heads are unable to faithfully capture complex, high-dimensional contextual patterns. To resolve this, we introduce the Prism Transformer, a novel architectural paradigm that replaces the static
The continuous drive for more efficient and robust large language models (LLMs) is pushing researchers to rethink foundational architectural components like multi-head attention.
This research introduces a novel architectural paradigm for Transformers that promises to significantly improve their ability to capture complex contextual patterns, leading to more capable AI.
The conventional uniform allocation of representational subspace in multi-head attention is replaced with a progressive head schedule, allowing early layers to handle higher-dimensional information.
