ComfyUi-ConditioningNoiseInjection
A custom node for ComfyUI that injects controlled noise into conditioning embeddings (like prompts) for a portion of the diffusion process.
ComfyUi-ConditioningNoiseInjection
A custom node for ComfyUI that injects controlled noise into conditioning embeddings (like prompts) for a portion of the diffusion process.
✨ Use case
-
Some models such as Z-Image Turbo exhibit low seed variance, meaning they generate very similar images even when the seed changes.
-
This node adds noise directly to the conditioning embeddings at the start of denoising, then restores the clean conditioning once the specified threshold is reached.
-
By perturbing the conditioning instead of the latent, you can:
- Increase compositional diversity
- Better preserve prompt adherence
📥 Installation
Navigate to the ComfyUI/custom_nodes folder, open cmd and run:
git clone https://github.com/BigStationW/ComfyUi-ConditioningNoiseInjection
Restart ComfyUI after installation.
