Researchers have introduced Grouped Query Experts (GQE), a novel mixture-of-experts layer designed to enhance the efficiency of Transformer models, particularly at long context lengths. GQE builds upon Grouped-Query Attention (GQA) by selectively activating query-head experts for each token, rather than applying all heads uniformly. This approach maintains the KV cache benefits of GQA while significantly reducing active query-head computation. In experiments, GQE achieved comparable downstream accuracy to a standard GQA baseline with half the activated query heads, using a 30B token budget at a 250M parameter scale. AI
IMPACT This method could lead to more efficient large language models, enabling longer context windows and reduced computational costs.
