Control various parameter settings for image generation to help you create ideal image effects.

​
Image Generation Parameter List

ParameterFormatDescription
Aspect Ratio--aspect, --arImages are initially square, but you can use the aspect ratio parameter to change this
Chaos--chaos, --cUse the chaos parameter to add variety to your image results
Character Reference--crefWant to use the same character across multiple images and scenes? You can provide character reference!
Negative Prompt--noUse the negative parameter to tell what you don’t want to see in the image
Quality--quality, --qUse the quality parameter to control image detail and processing time
Seed--seedUse the seed parameter for testing and experimentation
Stop--stopNeed a softer, more unique look? Use the stop parameter to finish images halfway
Raw Mode--rawUse raw mode to get more control over your images
Stylize--stylize, --sUse the stylize parameter to control artistic style in images
Style Reference--srefWant to match the look and feel of another image? You can provide style reference!
Tile--tileUse the tile parameter to create seamless tiled images
Version--version, --vUse version parameter to explore and switch between different model versions
Draft--draftGenerate draft images using half GPU power in V7 and above
Weird--weird, --wUse the weird parameter to make your images strange and unconventional
Fast--fastSwitch your GPU speed to fast mode
Image Weight--iwControl the influence of image prompts
Relax--relaxSwitch your GPU speed to relax mode
Turbo--turboSwitch your GPU speed to turbo mode
Niji--nijiUse our focused anime and East Asian aesthetic model
Experimental--expControl the aesthetic effects of image generation
Motion--motionControl video motion status (only supports video tasks)

Example Usage

A cute kitten --ar 16:9 --stylize 100
Beautiful landscape, sunset --quality 1 --chaos 50
Portrait --cref [reference image URL] --niji

Supported Aspect Ratios

Core aspect ratios and their typical applications:
  • 1:1 - Standard square, suitable for social media avatars, Instagram posts
  • 4:3 - Traditional rectangle, suitable for older monitors, tablets
  • 2:3 - Classic photography ratio, commonly used for frames, posters
  • 16:9 - Modern widescreen ratio, mainstream standard for HD video, smart TVs
  • 9:16 - Portrait ratio, optimized for mobile short videos, social media stories

​
Setting Aspect Ratios

You can quickly determine and set image aspect ratios through these methods:
  • Based on pixel dimensions: For 1920x1080 pixel images, input --ar 1920:1080, system automatically simplifies to --ar 16:9
  • Based on physical dimensions: For sizes like 8.5x11 inches, remove decimal points and input --ar 85:110
  • Custom ratios: Supports any integer ratios, such as --ar 3:2 or --ar 5:4

​
Important Notes

  • Default aspect ratio is 1:1, suitable for most basic scenarios
  • Only supports integer ratios, use 139:100 instead of 1.39:1
  • Different model versions may have varying support for aspect ratios
  • Extreme aspect ratios (like 1:10 or 10:1) are experimental features with potentially unstable results
  • During HD processing, some aspect ratios may be fine-tuned for optimization

​
Parameter Combination Suggestions

  • High Quality Detailed Images: --quality 1 --stylize 250
  • Creative Experimentation: --chaos 75 --stylize 50
  • Character Consistency: --cref [character image] --seed [fixed value]
  • Style Matching: --sref [style image] --stylize 100

​
Current Limitations

The API currently does not support the following parameters:
  • --repeat parameter
  • --personalize parameter
  • {} prompt arrangement syntax
  • --stealth/--public parameters

​
Important Usage Requirements

  • When using enhance: The original job must be created in draft mode with parameters --v7 --draft
  • Draft mode: Ultra-fast image prototyping (10x faster than normal mode) with slightly reduced quality but consuming only half the GPU resources. Use --draft parameter to activate.

​
Supported Speed Modes

Speed modes control the GPU type used for task execution, determining task execution time. The API provides fast mode and turbo mode, with relax mode currently not supported.

​
Fast Mode (--fast)

Fast mode is the default GPU speed mode where API requests are prioritized using GPU resources for processing. Usually completes image generation within 1 minute.
  • Usage: Activated with --fast parameter
  • Default: Used when no speed mode is specified
  • Processing Time: Typically under 1 minute for standard images

​
Turbo Mode (--turbo)

Turbo mode uses a high-performance GPU pool with processing speeds up to 4x faster than fast mode. This mode consumes double the GPU time quota and only supports v5 and above versions.
  • Usage: Activated with --turbo parameter
  • Speed: Up to 4x faster than fast mode
  • Requirements: Only supports v5+ versions
  • Cost: Consumes double GPU time quota
  • Status: Experimental feature - availability and billing may change
