GTNodes for ComfyUI

A bundle of nodes with different purposes. More info below.

Updates:

• 26/08/2026:
  • Updated SamplerCustomAdvancedEfficient: model input is now optional. Added audio decode option. Added option to disable cfg and negative inputs to slightly slim down the ui.
  • Linked ScheduledCfgGuiderClass to CFGGuider, and removed now redundant functions.
• Updated SamplerCustomAdvancedEfficient to work through comfyui Sampler Custom Advanced to support LTXV combined latent and future comfyui updates.
• Added ScheduledCfgGuider, CFGFloatListScheduler (taken from my Wan-TimeToMove) to support higher cfg values at first steps without needing Wan-TimeToMove.
• Removed redundant nodes.

Download

To install ComfyUI-GTNodes, follow these steps:

• Go in the ComfyUI custom_nodes folder, then download the repository or clone it here: git clone https://github.com/GiusTex/ComfyUI-GTNodes.
• Restart ComfyUI.

Nodes:

Sampler Custom Advanced (Efficient):

An edit of efficiency-nodes's ksampler adv. (eff.) to let it accept custom samplers, schedulers (sigmas) and guiders through comfyui Sampler Custom Advanced and other native nodes. Supports:

• internal slicing of the sigmas, useful for multi-stage sampling;
• use of only positive, useful when sampling with cfg 1 and/or the negative isn't required;
• use of optional custom samplers, schedulers and guiders. Connect and use them, or bypass/leave their input slots empty to use the corresponding default widgets. Default guiders: CFG Guider when use_cfg is True, Basic Guider when False.
• Decoding of images/audio, when one or both are available (the node auto-checks whats available in the latent).

Scheduled CFG Guider (with its CFG Float List Scheduler):

(Deprecated, although they still work; I advice to use comfyui's native CFG Override). Scheduled CFG Guider, anyway, let you decide what cfg to apply at each step through a list of floats connected to the cfg input. Based on kijai nodes.

Suggested resources:

• flowmatch scheduler: useful with video models using lightx loras;
• ScheduledCfgGuider: supports higher cfg values at first steps.
