Comfyui-PainterVRAM
English | 中文
English
A tiny ComfyUI custom node that reserves GPU VRAM before workflow execution to avoid OOM crashes.
Pick Manual to set the exact GB, or Auto to let the node calculate it from current usage; enable Clean GPU before for an instant memory purge.
No seeds, no extra outputs—just plug and go.
