tomevault-io Text-to-Image Generation
Transform your creative ideas into stunning images using cutting-edge AI image generation models.
Overview
This skill combines the power of Stability AI's Stable Diffusion and Black Forest Labs' FLUX models to generate high-quality images from text descriptions. Choose the right model based on your needs - photorealism, artistic styles, or text rendering.
Available Tools
Stability AI
- {{txt2img}}: Generate images using Stable Diffusion Ultra - great for artistic and creative outputs
FLUX Models (Black Forest Labs)
- {{flux_pro}}: FLUX Pro 1.1 - highest quality photorealistic generation with excellent text rendering
- {{flux_flex}}: Flexible generation with adjustable guidance scale for creative control
When to Use Each Tool
| Tool | Best For | Quality | Speed |
|---|---|---|---|
| {{flux_pro}} | Photorealistic images, product photos, text in images | Highest | ~30s |
| {{flux_flex}} | Creative freedom, artistic styles, experimentation | High | ~20s |
| {{txt2img}} | General purpose, diverse styles, quick iterations | High | ~10s |
Usage Examples
Example 1: Photorealistic Product Photography
Use {{flux_pro}} for the best photorealistic results:
{
"prompt": "Professional product photo of sleek wireless headphones on a marble surface, studio lighting, 4K, highly detailed",
"width": 1024,
"height": 1024,
"prompt_upsampling": true,
"output_format": "png"
}
Example 2: Artistic Illustration
Use {{txt2img}} for artistic and creative styles:
{
"prompt": "Watercolor painting of a cozy coffee shop in autumn, warm colors, artistic style",
"negative_prompt": "blurry, low quality, distorted",
"output_format": "png"
}
Example 3: Text in Images
Use {{flux_pro}} for accurate text rendering:
{
"prompt": "Motivational poster with the text 'Dream Big' in elegant typography, inspirational design",
"width": 768,
"height": 1024,
"prompt_upsampling": true
}
Example 4: Creative Experimentation
Use {{flux_flex}} with adjustable guidance for creative freedom:
{
"prompt": "Surreal landscape with floating islands, dreamlike atmosphere, fantasy art",
"guidance": 2.5,
"width": 1440,
"height": 768
}
Prompt Engineering Tips
Be Descriptive
More details lead to better results:
- ❌ "a dog"
- ✅ "a golden retriever puppy playing in autumn leaves, soft afternoon sunlight, shallow depth of field"
Specify Style
Include artistic style keywords:
- "cinematic lighting", "studio photography", "oil painting", "watercolor", "digital art"
- "4K", "highly detailed", "professional", "award-winning"
Use Negative Prompts (Stability AI)
With {{txt2img}}, exclude unwanted elements:
- "blurry, low quality, distorted, disfigured"
Aspect Ratios
Choose dimensions that match your content:
- 1024x1024: Square format, balanced compositions
- 1024x768: Landscape, scenic views
- 768x1024: Portrait, vertical subjects
- 1440x1024: Wide cinematic shots

Best Practices
- Start with {{flux_pro}} for most use cases - it provides the best quality
- Use prompt_upsampling to automatically enhance your prompts with more details
- Save your seeds to reproduce or iterate on good results
- Lower guidance (2-3) in {{flux_flex}} for more creative freedom
- Higher guidance (4-5) in {{flux_flex}} for strict prompt adherence
Important: Language Requirements
⚠️ All prompts MUST be in English!
The Stability AI and FLUX APIs only support English prompts. If the user provides a prompt in another language (e.g., Chinese, Japanese, Spanish), you MUST:
- Translate the user's prompt to English before calling the tool
- Enhance the translated prompt with descriptive English keywords
- Keep the original intent and style of the user's request
Translation Example
User request: "画一个可爱的男孩牵着小狗在公园散步"
Translated and enhanced prompt for the tool:
{
"prompt": "A cute young boy walking a friendly dog in a sunny park, warm lighting, heartwarming scene, high quality, detailed illustration, soft colors"
}
Always translate non-English prompts to detailed English descriptions before calling any image generation tool.
