Node Parameters

| Parameter | Type | Description | |-----------|------|-------------| | API Key | String | Your Replicate API token (starts with r8_) | | Prompt | String | Text description of what you want to generate | | Size Preset | Dropdown | Common aspect ratios (1:1, 4:3, 16:9, etc.) or Custom | | Width | Integer | Custom width in pixels (1024-4096, used with Custom preset) | | Height | Integer | Custom height in pixels (1024-4096, used with Custom preset) | | Max Images | Integer | Maximum images to generate (1-15, only with Sequential mode) | | Sequential Generation | Dropdown | disabled (single image) or auto (let AI decide multiple) | | Seed | Integer | Random seed for reproducible results (-1 for random) | | Control After Generate | Dropdown | Seed behavior after generation (fixed/increment/decrement/randomize) | | Image Input | Image | Optional reference image for image-to-image generation |

Features

  • Multiple aspect ratios with preset sizes
  • Sequential image generation for related image sets
  • Image-to-image support with reference images
  • Seed control for reproducible results
  • Real-time progress tracking with 4-stage progress updates
  • Automatic cancellation support with ComfyUI's cancel button
  • Error handling with content policy detection

Usage Tips

  • Use Sequential mode with prompts like "story sequence" or "character variations" for multiple related images
  • Custom dimensions work best for specific use cases outside standard ratios
  • Seed control lets you iterate on prompts while maintaining composition
  • Large input images may exceed data URL limits (shows warning)
