Inputs (7)

Name	Type	Default	Description
ckpt_name	COMBO		Select the base checkpoint diffusion model file from your models/checkpoints folder.
steps	INT	201–10000	The total number of sampling/denoising steps for base generation.
step_refiner	INT	100–10000	Target step count for refiner passes or the step transition threshold for multi-pass pipelines.
cfg	FLOAT	7.00–100	Classifier-Free Guidance (CFG) scale. Controls how strictly the model adheres to your prompt.
sampler_name	COMBO		The mathematical sampling algorithm used to generate or denoise the image (e.g., euler, dpmpp_2m).
scheduler	COMBO		The noise scheduling rate/curve across the steps (e.g., normal, karras, sgm_uniform, simple).
denoise	FLOAT	1.000–1	Denoise strength. Set to 1.0 for initial txt2img generation, or 0.20-0.60 for img2img / upscaling.
