UnverifiedHybrid architectures (linear attention + standard attention) are more efficient than pure full attention on long-context tasks, but linear attention may be slightly inferior to standard attention on certain reasoning tasks that require precise global dependencies75% similarUnverifiedThe computational complexity of standard self-attention is quadratic with respect to sequence length, and achieving a context of one million tokens requires introducing techniques such as sparse attention, sliding window attention, and KV Cache compression.74% similarVerifiedThe Multi-Query Attention technique allows multiple attention heads to share a single set of Key and Value projection matrices, compressing KV cache memory requirements to 1/H of the original, at the cost of a slight reduction in model expressiveness.69% similarUnverifiedIn hybrid attention architectures, the lower layers use Full Attention to capture global semantics, while the upper layers use Sliding Window to improve efficiency.69% similarUnverifiedAcademic research has explored linear attention, Softmax-free attention, and kernel method approximations in multiple studies, attempting to replace the quadratic complexity of standard attention with linear complexity69% similar
