ComfyUI Configuration¶

Variable	Description	Default
`COMFYUI_EXTRA_ARGUMENTS`	Additional arguments for the ComfyUI CLI
`VRAM_THRESHOLD`	VRAM threshold in GB for selecting the model	Image: 38 GB; LTX/WAN: 36 GB
`COMFYUI_START_MAX_TRIES`	Number of tries to wait until ComfyUI is online; depends on vCPU speed	60

Change HF_MODEL_ to HF_MODEL_LVRAM_ or HF_MODEL_HVRAM_ to make loading VRAM dependent through VRAM_THRESHOLD.
