​

Supported Aspect Ratios

• 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

• 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

​

Detailed Parameter Guidelines

​

Stylize Parameter Effects

• --s 0: Very literal, follows prompt closely
• --s 25: Slight artistic interpretation
• --s 50: Balanced between literal and artistic

• --s 100: Default value, good balance
• --s 200: More artistic interpretation
• --s 250: Strong artistic styling

• --s 500: Very artistic, may deviate from prompt
• --s 750: Extremely artistic
• --s 1000: Maximum artistic interpretation, minimal prompt adherence

​

Chaos Parameter Effects

• --c 0: Default, very consistent results
• --c 15: Slight variation
• --c 25: Moderate variation while staying on-theme

• --c 50: Significant variation
• --c 75: High variation, experimental
• --c 100: Maximum chaos, very unpredictable results

​

Quality Parameter Impact

• --q 0.25: 4x faster, lower detail (draft quality)
• --q 0.5: 2x faster, moderate detail
• --q 1: Default quality and speed
• --q 2: 2x slower, maximum detail (only v4+)

​

Weird Parameter Effects

• --w 0: Default, no weirdness
• --w 100: Slightly unusual elements
• --w 250: Noticeable strange elements

• --w 750: Very unusual and surreal
• --w 1500: Extremely weird and abstract

• --w 2500: Highly abstract and bizarre
• --w 3000: Maximum weirdness, often unrecognizable

​

Seed Parameter Usage

• Consistency: Same seed + prompt = similar results
• Variations: Change other parameters while keeping seed
• Experimentation: Test different prompts with same seed
• Reproducibility: Share exact results with others

• Seeds only work with same model version
• Different aspect ratios may produce different results even with same seed
• Seeds from older model versions won’t work with newer versions

​

Parameter Combination Suggestions

• High Quality Detailed Images: --quality 1 --stylize 250 --chaos 10
• Creative Experimentation: --chaos 75 --stylize 50 --weird 500
• Character Consistency: --cref [character image] --seed [fixed value] --chaos 0
• Style Matching: --sref [style image] --stylize 100 --iw 1.5
• Realistic Photography: --stylize 50 --quality 1 --raw
• Abstract Art: --stylize 750 --weird 1000 --chaos 80
• Anime/Manga Style: --niji 6 --stylize 200 --quality 1
• Multiple Variations: --chaos 25 --stylize 150

​

Current Limitations

• --repeat parameter
• --bs, --batchsize parameter (only supported in video functions with values [1,2,4])
• --personalize parameter
• {} prompt variation syntax
• --stealth/--public parameters
• --video parameter (use video-specific endpoints instead)

​

Object Reference (—oref) - V7 Update

​

Usage

A small duck holding a magic wand --oref http://image.png

​

Important Limitations (V7)

• Incompatible with V6.1 features: Object reference is incompatible with features that still use V6.1 (such as inpainting or outpainting)
• Double GPU consumption: Using object reference consumes 2x GPU time compared to regular V7 images
• Editing incompatibility: Object reference images are currently incompatible with regional inpainting, pan, or outpaint. To edit these images, use the Edit interface and remove image references along with any --oref or --ow parameters
• Speed mode incompatibility: Object reference is currently incompatible with speed modes or --q 4

​

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

​

Fast Mode (--fast)

• 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)

• 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

​

Prompt Best Practices

​

Effective Prompt Structure

1. Subject: What you want to see (e.g., “portrait of a woman”)
2. Style/Medium: Art style or medium (e.g., “oil painting”, “digital art”)
3. Details: Specific details (e.g., “blue eyes, flowing hair”)
4. Environment: Setting or background (e.g., “in a garden”, “studio lighting”)
5. Parameters: Add parameters at the end

Portrait of an elderly wizard, oil painting style, long white beard, wise eyes, wearing purple robes, mystical library background --ar 2:3 --stylize 200 --quality 1

​

Parameter Order Recommendations

1. Aspect ratio (--ar)
2. Quality (--quality)
3. Stylize (--stylize)
4. Chaos (--chaos)
5. Weird (--weird)
6. Speed mode (--fast, --turbo)
7. Model version (--v, --niji)
8. Special modes (--raw, --tile, --draft)

​

Common Mistakes to Avoid

• Too many conflicting parameters: Keep combinations logical
• Extreme parameter values: Start with moderate values and adjust
• Inconsistent aspect ratios: Choose ratios that match your intended use
• Overuse of chaos: High chaos can make results unpredictable
• Wrong model versions: Use appropriate version for your style needs
