tomevault-io FLUX Image Generation
State-of-the-art AI image generation using Black Forest Labs' FLUX models.
Overview
This skill provides access to FLUX, one of the most advanced AI image generation models available. FLUX excels at photorealistic imagery, complex compositions, and accurate text rendering in images.
Available Tools
Text-to-Image
- {{flux_pro}}: High-quality image generation with FLUX Pro 1.1
- {{flux_flex}}: Flexible generation with adjustable guidance scale
Image Editing
- {{flux_kontext}}: Context-aware image editing and transformation
- {{flux_fill}}: Inpaint/fill masked regions of images
- {{flux_expand}}: Outpaint/extend images beyond boundaries
Key Features
Superior Quality
FLUX Pro 1.1 represents the cutting edge of image generation, with:
- Exceptional photorealism
- Accurate text rendering in images
- Complex multi-subject compositions
- Consistent style and coherence
Context Understanding
FLUX Kontext understands image context to make intelligent edits:
- Object modification while preserving surroundings
- Style transformation with content preservation
- Seamless blending of edited regions
Usage Examples
Example 1: Generate High-Quality Image
Use {{flux_pro}} for photorealistic generation:
{
"prompt": "Professional product photo of a smartwatch on marble surface, studio lighting",
"width": 1024,
"height": 1024,
"prompt_upsampling": true,
"output_format": "png"
}
Example 2: Edit with Context
Use {{flux_kontext}} for context-aware transformations:
{
"prompt": "Change the season from summer to winter, add snow to the ground and trees",
"guidance": 3.5
}
Blob inputs: image (summer photo to edit)
Example 3: Expand Canvas
Use {{flux_expand}} to outpaint image boundaries:
{
"prompt": "Continue the background scenery naturally",
"top": 256,
"bottom": 0,
"left": 128,
"right": 128
}
Blob inputs: image (portrait to expand)
Example 4: Fill Region
Use {{flux_fill}} with a mask to fill specific areas:
{
"prompt": "Beautiful sunset sky with orange and purple clouds",
"guidance": 3.5,
"prompt_upsampling": true
}
Blob inputs: image (source photo), mask (sky region marked white)
Parameters
Common Parameters
| Parameter | Description | Default |
|---|---|---|
| prompt | Text description of desired output | Required |
| width/height | Output dimensions (256-1440) | 1024 |
| seed | Random seed for reproducibility | Random |
| output_format | png or jpeg | png |
Generation Parameters ({{flux_pro}}, {{flux_flex}})
| Parameter | Description | Default |
|---|---|---|
| guidance | Guidance scale (1.5-5) | 3.5 |
| prompt_upsampling | Auto-enhance prompts with details | false |
| safety_tolerance | Content filter level (0-6) | 2 |
Expand Parameters ({{flux_expand}})
| Parameter | Description | Default |
|---|---|---|
| top | Pixels to expand at top | 0 |
| bottom | Pixels to expand at bottom | 0 |
| left | Pixels to expand at left | 0 |
| right | Pixels to expand at right | 0 |
Best Practices
- Prompt Upsampling: Enable for more detailed results with {{flux_pro}}
- Guidance Scale: Lower (2-3) for creative freedom, higher (4-5) for prompt adherence
- Safety Tolerance: Adjust based on content needs (0=strict, 6=permissive)
- Seed Usage: Save seeds to reproduce or iterate on good results
Important: Language Requirements
⚠️ All prompts MUST be in English!
FLUX APIs only support English prompts. If the user provides a prompt in another language (e.g., Chinese, Japanese, Spanish), you MUST:
- Translate the prompt to English
- Enhance with descriptive keywords while preserving the original intent
Example: "可爱的男孩遛狗" → "A cute young boy walking a friendly dog in a sunny park, warm atmosphere, heartwarming scene, high quality"
Limitations
- Async processing with polling (may take 10-60 seconds)
- Maximum dimensions: 1440x1440 pixels
- Some content filtered by safety systems
- API rate limits apply
- Prompts must be in English only
