Use Cases

• Rapid Prototyping: Quick image generation for concept validation
• Content Creation: Generate visuals for social media, blogs, and marketing
• Art Creation: Create digital artwork and illustrations
• Product Design: Generate product concepts and design variations

Tips for Best Results

1. Prompt Quality: Be specific and descriptive

   • Good: "A peaceful sunset over a calm ocean with golden light reflecting on the water"
   • Avoid: "A sunset"

2. Negative Prompts: Use to exclude unwanted elements

   • Examples: "blurry, low quality, distorted, watermark, text"

3. Aspect Ratios: Choose based on your use case:

   • 1:1: Perfect for social media posts
   • 16:9: Great for banners and presentations
   • 2:3: Ideal for portrait compositions
   • 9:16: Perfect for mobile-first content

4. Style Presets: Experiment with different styles:

   • photographic: For realistic images
   • digital-art: For artistic illustrations
   • cinematic: For movie-like quality
   • anime: For animated style

5. Seeds: Use consistent seeds for reproducible results

Notes

• Stable Image Core offers faster generation times compared to Stable Diffusion XL
• The model excels at understanding natural language prompts
• Multiple aspect ratios are supported without quality degradation
• Results are typically generated in under 10 seconds
