arXiv:2606.20945v2 Announce Type: replace Abstract: Self-attention is central to Transformer performance and is often the most expensive part of the Transformer at long context lengths because its pairwise token interactions scale quadratically with sequence length. Standard dense attention also applies the same set of attention heads to every token regardless of token difficulty or information content. This uniform activation can waste compute, especially as sequences grow longer and attention cost increases rapidly. We propose Grouped Query Experts (GQE), a mixture-of-experts layer on top of
The continuous drive to improve Transformer efficiency, especially for long context lengths, makes research into advanced attention mechanisms like GQE critical at this moment.
This development addresses a fundamental limitation in large language models by significantly reducing computational cost, which directly impacts the scalability and accessibility of advanced AI systems.
The computational cost associated with Transformer self-attention, particularly at longer sequence lengths, is potentially reduced, enabling more efficient and potent AI models.
