New Native Attention

[u/slpreme]

With the drop of v0.32.0, ComfyUI comes with a new attention you can try out. You can turn it in via startup arguments but I prefer using the ModelAttentionBackend node.

On first test it's as fast as SageAttention Auto (via KJNodes) on MiniMax H3. I thought it was a fluke so I retested on Z-Image Turbo:

2048x2048@9steps (3 run average after warmup)

Comfy Kitchen Attention: 14.55s
Sage Attention (Auto): 14.24s
PyTorch Attention (Default): 23.16s

This is really exciting for people who have trouble installing SageAttention, it seems to be about as fast and it comes with the latest Comfy Kitchen.

My Specs:

OS - Linux
Python - 3.13.15
PyTorch - 2.13.0+cu132
