Use Cases

• Art Creation: Generate digital artwork, illustrations, and concept art
• Content Marketing: Create visual content for social media and marketing campaigns
• Product Design: Generate product concepts and design iterations
• Storytelling: Create visual narratives and storyboards

Tips for Best Results

1. Prompt Quality: Be descriptive and specific in your prompts

   • Good: "A serene Japanese garden with cherry blossoms, stone lanterns, and a small pond reflecting the moonlight"
   • Avoid: "A garden"

2. CFG Scale:

   • Lower values (3-7): More creative, less adherence to prompt
   • Higher values (7-15): Stronger adherence to prompt
   • Very high values (15+): May cause artifacts

3. Steps:

   • 20-30 steps: Good balance of quality and speed
   • 30-50 steps: Higher quality, longer generation time

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

   • 1024x1024: Perfect for social media posts
   • 1344x768: Great for banners and headers
   • 832x1216: Ideal for portrait compositions

5. Style Presets: Experiment with different styles:

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

Notes

• Generation time varies based on complexity and parameters
• Higher step counts and advanced CLIP guidance increase generation time
• Seed values ensure reproducible results when other parameters remain constant
