    ✴️ The Nodes

    ModelParamsPipeNode

    Create a "pipe" containing the selected model, CLIP, VAE, and all generation parameters (steps, CFG, sampler, scheduler, tags, etc).
    Makes it easy to pass model settings between nodes.

    ParamsPipeUnpack

    Unpack all parameters and objects from a pipe: model, CLIP, VAE, steps, CFG, sampler, scheduler, tags.

    KSamplerPipeNode

    A sampler node that takes a pipe, conditioning, seed, denoise, and either latent or image_override.
    Works with any model passed via the pipe.

    PromptBuilderNode

    Build final positive/negative texts and CLIP conditioning, taking into account styles (from JSON), base texts, tags, and img2txt.
    Supports custom styles for advanced prompt engineering.

    ListSelectorNode

    Select an item from a list by index.
    Useful for UI and dynamic workflows.

    DenoiseSelector

    Simple node for selecting the denoise value.

    ActiveModel

    Dummy node for JavaScript-side integration (client logic).

    MySwitchIndex (Multi Model Switch)

    Вузол для вибору одного з декількох вхідних сигналів. Працює у двох режимах:

    <ul> <li><b>firstActive</b> — повертає перший не-порожній (не None) вхід та його індекс.</li> <li><b>index</b> — повертає вхід із заданим індексом (1-базований), якщо він не порожній.</li> </ul> Динамічно керує кількістю входів через UI. Повертає обране значення та його індекс (або 0, якщо не знайдено). <br> <b>Корисно для мульти-модельних пайплайнів, умовної маршрутизації, вибору активного результату.</b>

    🎨 Styles

    • Styles are stored in the Styles folder inside this package.
    • For dynamic style selection, the API endpoint /multi_model/get_style_names is used.
    • A style is a JSON or YAML file containing an array of objects, each with name, prompt, and negative_prompt fields.

    ⚡ Installation

    Manual Install

    1. Copy the MultiModel folder to ComfyUI/custom_nodes/.
    2. Restart ComfyUI.

    🚀 Example Usage

    1. Add ModelParamsPipeNode to select your model and parameters.
    2. Build prompts using PromptBuilderNode (optionally connect styles).
    3. Use KSamplerPipeNode to generate images.
    4. For multi-model pipelines, add several pipes and switch between them using MySwitchIndex.
