    UCloud ModelVerse API for ComfyUI

    This plugin provides seamless integration with UCloud's ModelVerse API, enabling you to use powerful AI models directly within ComfyUI for image generation and editing tasks.

    Quick Start

    Installation

    1. Install via Custom Node Manager (Recommended)

      • Open ComfyUI
      • Go to Manager → Custom Nodes Manager
      • Search for "ComfyUl-UCloud"
      • Click Install
      • Restart ComfyUI

    2. Configure API Key

      • Get your API key: Console En, Console Zh
      • Add your UCloud ModelVerse API key in the Modelverse Client node
      • Alternatively, create a config.ini file with MODELVERSE_API_KEY=your_api_key

    Basic Usage

    1. Add a Modelverse Client node to your workflow
    2. Choose your desired model from the supported models below
    3. Connect the appropriate input/output nodes
    4. Run your workflow

    Supported Models

    Our plugin supports the following models, each optimized for specific use cases:

    • Flux Dev - Foundation model with strong stylization capabilities
    • Flux Kontext Pro Text2Image - Specialized for text-to-image generation
    • Flux Kontext Pro - Expert single image editing and enhancement
    • Flux Kontext Pro (Multi-inputs) - Batch processing for multiple images
    • Flux Kontext Max Text2Image - Premium text-to-image generation with highest quality
    • Flux Kontext Max - Flagship single image editing with advanced features
    • Flux Kontext Max (Multi-inputs) - Most powerful multi-image processing
    • Step1X-Edit - Precision local editing and inpainting

    Note: (Multi-inputs) models use the same node interface as their single-input counterparts. Check the example workflows below for implementation details.

    Example Workflows

    Build your own workflow with Modelverse nodes. You can check the following images, drag them into ComfyUI GUI and autoload example workflows.

    | Flux Dev | Flux Kontext Pro | Flux Kontext Max (Multi-inputs) | |:-:|:-:|:-:| | <img src="assets/flux_dev.png" width="200" height="200"> | <img src="assets/flux_kontext_pro_single.png" width="200" height="200"> | <img src="assets/flux_kontext_max_multi.png" width="200" height="200"> |
