Comfyui-Sparse-Attention
This is a standalone version of the ComfyUI-H3-SLA-Attention node from
ComfyUI-PlagueKind-Nodes pack, all credit goes to the original authors listed below.
Important note
By default this node won't trigger at all on lower resolutions/lengths (ie: 512x512) because those generations fall outside the default 8192 sequence length. You can of course lower this limit, but results might be worse.
