Quick read

A user interface showing a custom node that allows instant cancellation of tasks in ComfyUI, streamlining the workflow for WAN video projects.

A surge of user feedback has driven advances in ComfyUI's cancellation features. Many users express frustration over the lengthy waits required to stop running tasks, especially when handling large WAN videos. Community members have developed a custom node that promises instant cancellation, enhancing the overall experience.

New Insights from the Community

While the ModelPatchFastTerminate custom node addresses cancellation delays, users have raised questions about installation issues and workflow impacts. One user mentioned, "Iโ€™m unsure if I placed the script correctly. Should it be directly in the custom_nodes folder?" This highlights ongoing confusion around installation processes.

Installation Challenges and Clarification

Some users reported errors during setup, such as:

"I'm unable to get it to load for me. I get this error message: FileNotFoundError. Any thoughts?"

Clearer installation guidelines might be necessary as the community works toward smoother implementation of the custom node. Interest also lingers around making this feature a default option within ComfyUI, with one comment noting, "This is what we all hoped for. ComfyUI needs this upgrade!"

Performance and User Interaction

People are concerned not just about cancellation speed but also about maintaining workflow efficiency. A user pointed out, "Can canceled runs be removed from the processing line to avoid delays?" This reflects a desire for better processing management, further demonstrating the need for effective solutions.
