Load Diffusion Model Hub Pro

Central parameter hub that loads a diffusion/UNET model and routes MODEL, steps, refiner steps, CFG, sampler algorithm, scheduler curve, denoise values, positive/negative prompts, and metadata across workflows.

    Inputs (10)

    NameTypeDefaultDescription
    unet_nameCOMBONoneSelect the diffusion / UNET model file from your models/diffusion_models or models/unet folder.
    stepsINT201–10000The total number of sampling/denoising steps for base generation.
    step_refinerINT100–10000Target step count for refiner passes or the step transition threshold for multi-pass pipelines.
    cfgFLOAT7.00–100Classifier-Free Guidance (CFG) scale. Controls how strictly the model adheres to your prompt.
    sampler_nameCOMBOThe mathematical sampling algorithm used to generate or denoise the image (e.g., euler, dpmpp_2m).
    schedulerCOMBOThe noise scheduling rate/curve across the steps (e.g., normal, karras, sgm_uniform, simple).
    denoiseFLOAT1.000–1Denoise strength. Set to 1.0 for initial txt2img generation, or 0.20-0.60 for img2img / upscaling.
    positive_promptSTRINGEnter positive prompt text. Expanding the node will enlarge this text box.
    negative_promptSTRINGEnter negative prompt text. Expanding the node will enlarge this text box.
    metadataSTRINGSingle-line metadata text or workflow tags to pass downstream.
