UnverifiedThe workflow supports running on devices with limited VRAM through sparse attention and a low-VRAM mode (chunked processing and attention mechanism optimization).76% similarUnverifiedExisting mainstream sparse attention methods filter interactions by retaining entries with larger values or high-quality regions in the attention matrix.76% similarUnverified标准Attention的显存消耗随序列长度平方增长，Flash Attention将其压缩到线性增长76% similarUnverifiedLinear attention is better suited to NPU chips due to the static graph characteristics of its fixed computation, whereas traditional attention uses dynamic graphs that require chips to frequently switch scheduling.75% similarUnverifiedToken pruning or compression methods that rely on attention weights are difficult to combine with FlashAttention, because FlashAttention does not materialize and store the attention matrix during computation, making it hard for external modules to read directly.75% similar
