Thanks again for your model. when using your workflow I get a log from comfyui.
'[INFO] VSA: extra_tokens ignored (the trained sparse pattern is the target)'
I heard the fastvideo twice the speed using vsa attention, but result not as that fast
You're welcome,
You can switch to the default workflow to see if the issue is the workflow. However, I’m seeing the boost.
Default workflow: https://raw.githubusercontent.com/Comfy-Org/workflow_templates/main/templates/video_fastvideo_fasth3_i2v.json
