A simple workflow for Klein family models in the first row was developed for 9b and 4b distilled versions, but it should work for base models with minimal changes (such as replacing ConditioningZeroOut with negative conditioning).

I am having some problems with publishing my extension in ComfyUI Manager; the "update" button does not appear. If you have issues like "missing node," even though you've already downloaded my extension, try pushing "try update" or "switch version" and choosing "latest." Or you may clone it manually into your "custom nodes" from https://github.com/DemonAlone/DemonAlone-nodes-ComfyUI.
